Allah says: "There is no compulsion in religion", meaning: do not force anyone to embrace Islam, because it is clear and its proofs and evidences are… - Ibn Kathir

Also (forbidden are) women already married, except those whom your right hands possess. The Ayah means, you are prohibited from marrying women who are already married, except those whom your right hands possess, except those whom you acquire through war, for you are allowed such women after making sure they are not pregnant. Imam Ahmad recorded that Abu Sa`id Al-Khudri said, "We captured some women from the area of Awtas who were already married, and we disliked having sexual relations with them because they already had husbands. So, we asked the Prophet about this matter, and this Ayah was revealed, Also (forbidden are) women already married, except those whom your right hands possess. Consequently, we had sexual relations with these women." This is the wording collected by At-Tirmidhi An-Nasa'i, Ibn Jarir and Muslim in his Sahih.

The Sunni Ibn Kathir explains that the allowance of taking unbelievers as friends for the purpose of “guarding yourselves against them” was for “those believers who in some areas or times fear for their safety from the disbelievers. In this case, such believers are allowed to show friendship to the disbelievers outwardly, but never inwardly. For instance, Al-Bukhari recorded that Abu Ad-Darda’ said, ‘We smile in the face of some people although our hearts curse them.’ Al-Bukhari said that Al-Hasan said, ‘The Tuqyah [taqiyyah ] is allowed until the Day of Resurrection.’”

Oh God, highest friend in heaven!
