He then marched and encamped under the fort of Delhi... The city and its vicinity were freed from idols and idols-worship, and in the sanctuaries of the images of the Gods, mosques were raised by the worshippers of one God.'...
'Kutbu-d din built the Jami' Masjid at Delhi, and adorned it with stones and gold obtained from the temples which had been demolished by elephants, and covered it with inscriptions in Toghra, containing the divine commands.
founded of the Mamluk Dynasty (1150-1210)
Quṭb al-Dīn Aibak also known as Quṭb ud-Dīn Aibak or Qutub ud-Din Aybak, (1150 – 1210) was a general of the Ghurid king Mu'izz ad-Din Muhammad Ghori. He was in-charge of the Ghurid territories in northern India, and after Mu'izz ad-Din's death, he became the ruler of an independent kingdom that evolved into the Delhi Sultanate ruled by the Mamluk dynasty.

In the year AH 599 (AD 1202), Kutbu-d dîn proceeded to the investment Kãlinjar, on which expedition he was accompanied by the Sãhib-Kirãn, Shamsu-d dîn Altamsh… The temples were converted into mosques and abodes of goodness, and the ejaculations of bead-counters and voices of summoners to prayer ascended to high heaven, and the very name of idolatry was annihilated…
Kutbu-d din marched from Kohram 'and when he arrived at Mirat -which is one of the celebrated forts of the country of Hind, for the strength of its foundations and superstructure, and its ditch, which was as broad as the ocean and fathomless-an army joined him, sent by the dependent chiefs of the country'. The fort was captured, and a Kotwal appointed to take up his station in the fort, and all the idol temples were converted into mosques.
The Government of the fort of Kohram and of Samana was made over by the Sultan to Kutbu-d din... [who] by the aid of his sword of Yemen and dagger of India became established in independent power over the countries of Hind and Sind' He purged by his sword the land of Hind from the filth of infidelity and vice, and freed the whole of that country from the thorn of God-plurality, and the impurity of idol-worship, and by his royal vigour and intrepidity, left not one temple standing
Shahabud-din Ghori, king of Ghazni, sent his slave, Kutbu-d din, to make war against the provinces of Hind, and this general made an incursion in which he killed many, and returned home with prisoners and booty. The king of Benares was the greatest king in India, and possessed the largest territory, extending lengthwise from the borders of China to the province of Malawa (Malwa), and in breadth from the sea to within ten days’ journey to Lahore. When he was informed of this inroad, he collected his forces, and in the year 590 (1194 A.D.), he entered the territories of the Muhammadans, [p.108] Shahabu-d din Ghori marched forth to oppose him, and the two armies met on the river Jumna, which is a river about as large as the Tigris at Musal. The Hindu prince had seven hundred elephants, and his men were said to amount to a million. There were many nobles in his army. There were Mussulmans in that country since the days of Mahmud bin Subuktigin, who continued faithful to the law of Islam, and constant in prayer and good works. When the two armies met there was great carnage; the infidels were sustained by their numbers, the Musulmans by their courage, but in the end the infidels fled, and the faithful were victorious. The slaughter of the Hindus was immense; none were spared except women and children, and the carnage of the men went on until the earth was weary. Ninety elephants were captured, and of the rest some were killed, and some escaped. The Hindu king was slain, and no one would have recognized his corpse but for the fact of his teeth, which were weak at their roots, being fastened in with golden wire. After the flight of the Hindus Shabadu-d din entered Benares, and carried off its treasures upon fourteen hundred camels. He then returned to Ghazni. Among the elephants which were captured there was a white one. A person who saw it told me that when the elephants were brought before Shahabu-d din, and were ordered to salute, they all saluted except the white one. No one should be surprised at what I have said about the elephants, for they understand what is said to them. I myself saw one at Musal with his keeper, which did whatever his keeper told him.
[Qutub-ud-din Aibak] was a typical specimen of the ferocious Central Asian warriors of the time, merciless and fanatical. His valour and profuse liberality to his comrades endeared him to the bloodthirsty historian of his age, who praises him as having been a ' beneficent and victorious monarch. …His gifts were bestowed by hundreds of thousands, and his slaughters likewise were by hundreds of thousands. All the leaders in the Muslim conquest of Hindostan similarly rejoice in committing wholesale massacres of Hindu idolaters, armed or unarmed.
About this time they wrote to the heavenly throne, that the Rai who had fled from Dehli had raised an army of idolatrous, turbulent, and rebellious tribes, the vapour of pride and conquest havingentered his thoughtless brain." Kutbu-d din pursued him, " and when the wretch was taken, his head was severed from his body and sent to Dehli, which had been his residence and capital." Kutbu-d din then himself returned to Dehli, and sent " written accounts of his capture of forts and strongholds, and his victories and holy wars" to Ghazna, to which capital he was invited to receive thanks in person from Muizzu-d din Sam Ghori.
In Aibak’s expedition to Benares, ‘which was the centre of the country of Hind… here they destroyed nearly one thousand temples, and raised mosques on their foundations; and the knowledge of the law (Sharia) became promulgated, and the foundations of religion were established,’ adds Nizami. In January 1197, Qutbuddin Aibak advanced against Nahrwala, the capital of Gujarat and ‘fifty thousand infidels were dispatched to hell by the sword and from the heaps of the slain, the hills and the plains became of one level’ and ‘more than twenty thousand slaves, and cattle beyond all calculation fell into the hands of the victors.’ On Aibak’s brilliant achievement in the expedition to Kalinjar in 1202, records Nizami: ‘The temples were converted into mosques… and the voices of summoners to prayer ascended to the highest heaven and the very name of idolatry was annihilated.’ ‘Fifty thousand came under the collar of slavery and the plain became black as pitch with Hindus,’ continues Nizami.
Hindu learning in general was suppressed since Hindu and Buddhist schools were attached to temples and monasteries. These were regularly destroyed from the very beginning and with them schools of learning. Qutbuddin Aibak razed the Sanskrit College of Vishaldeva at Ajmer and in its place built a mosque called Arhai din ka Jhonpra. In the east Ikhtiyauddin Bakhtiyar Khalji sacked the Buddhist university centres in Bihar like Odantapuri, Nalanda and Vikramshila between 1197-1202.
When Qutbu'd-Din, the commander-in-chief of Muizzu'd-Din Sam alias Shihabu'd-Din Ghuri, conquered Delhi in AH 587 corresponding to AD 1191 corresponding to 1248 Bikarmi, this idol-house (of Rai Pithora) was converted into a mosque. The idol was taken out of the temple. Some of the images sculptured on walls or doors or pillars were effaced completely, some were defaced. But the structure of the idol-house kept standing as before. Materials from twenty-seven temples, which were worth five crores and forty lakhs of Dilwals, were used in the mosque, and an inscription giving the date of conquest and his own name was installed on the eastern gate…"When Malwah and Ujjain were conquered by Sultan Shamsu'd-Din in AH 631 corresponding to AD 1233, then the idol-house of Mahakal was demolished and its idols as well as the statue of Raja Bikramajit were brought to Delhi, they were strewn in front of the door of the mosque…""In books of history, this mosque has been described as Masjid-i-Adinah and Jama' Masjid Delhi, but Masjid Quwwat al-Islam is mentioned nowhere. It is not known as to when this name was adopted. Obviously, it seems that when this idol-house was captured, and the mosque constructed, it was named Quwwat al-Islam…"
Ibn-ul-Asir says that Qutbuddin Aibak made “war against the provinces of Hind… He killed many, and returned home with prisoners and booty.” In Banaras, according to the same authority, Muhammad Ghauri’s slaughter of the Hindus was immense. “None was spared except women and children." No wonder that slaves began to fill the households of every Turk from the very beginning of Muslim rule in India. Fakhr-i-Mudabbir informs us that as a result of the Muslim achievements under Muhammad Ghauri and Qutbuddin Aibak, “even a poor householder (or soldier) who did not possess a single slave before became the owner of numerous slaves of all description …”
For instance, when Muhammad Ghauri and Qutbuddin Aibak mounted a combined attack on the Khokhars of the Salt Range (Koh-i-Jud), “great plunder was taken and many captives, so that five Hindu [Khokhars] captives could be bought for a dinar”. Captives were so plentiful that they were also sent “to sell in Khurasan, not long after.”
The congregational mosque at Delhi named, purposefully, as the Masjid Quwwatul Islam (Might of Islam), was commenced by Aibak in 592/1195 within two years of its conquest. It was built with materials and gold obtained by destroying 27 Hindu and Jain temples in Delhi and its neighbourhood. A Persian inscription in the mosque testifies to this. The mosque at Ajmer erected by Qutbuddin Aibak soon after its occupation and known as the Arhai din ka Jhonpra, was also built from materials obtained from demolished temples. The Qutb Minar, planned and commenced by Aibak sometime in or before 1199 and completed by Iltutmish, was also constructed with similar materials, “the sculptured figures on the stones being either defaced or concealed by turning them upside down.” “In this improvisation,” rightly observes Habibullah, “was symbolised the whole Mamluk history”.
Ibn Asir only says that Qutbuddin Aibak made ‘war against the provinces of Hind… He killed many, and returned with prisoners and booty.” In Banaras, according to the same author, “the slaughter of the Hindus was immense, none was spared except women and children,”16 who would have been enslaved as per practice.
