If Ali says a mosquito can pull a plow, don't ask how. Hitch him up. - Muhammad Ali

'Atiyya ibn 'Urwa as-Sa'di, the Companion, said, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'The slave [of Allah] will not achieve the status of being one of the Godfearing until he leaves what does not concern him out of consideration for what does concern him."

Narrated Abu Qilaba: Allah's Apostle said, "The blood of a Muslim who confesses that none has the right to be worshipped but Allah and that I am His Apostle, cannot be shed except in three cases: In Qisas for murder, a married person who commits illegal sexual intercourse and the one who reverts from Islam (apostate) and leaves the Muslims."

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Once a man was walking along a road and became very thirsty. He found a well, climbed down into it and drank. When he came out, he saw a dog driven by thirst to eat mud. He said, 'This dog has reached the same extreme of thirst that I had reached.' So he climbed back down the well, filled his leather sock with water and, holding it between his teeth, climbed back up and let the dog drink Allah thanked him for that and forgave him." They said, "Messenger of Allah, do we then receive a reward on account of animals?'" He said, "There is a reward for every live animal [lit. everything with a moist liver]."
