"And if you fear that you cannot act equitably towards orphans, then marry such women as seem good to you, two and three and four; but if you fear that you will not do justice (between them), then (marry) only one or what your right hands possess; this is more proper, that you may not deviate from the right course." - Quran 4:3 (read more)

"Narrated Kurib: the freed slave of Ibn 'Abbas, that Maimuna bint Al-Harith told him that she manumitted a slave-girl without taking the permission of the Prophet. On the day when it was her turn to be with the Prophet, she said, "Do you know, O Allah's Apostle, that I have manumitted my slave-girl?" He said, "Have you really?" She replied in the affirmative. He said, "You would have got more reward if you had given her (i.e. the slave-girl) to one of your maternal uncles." - Sahih Bukhari 3:47:765 (read more)

"It is said that the kaafirs, Jews, Christians and communists in the east and the west all keep dogs, Allaah forbid. Each one takes his dog with him and cleans it every day with soap and other cleansing agents. But even if he were to clean it with the water of all the seas in the world and all the soap in the world, it would never become pure! Because its impurity is inherent, and inherent impurity cannot be cleansed except by destroying it and erasing it altogether." - Shaykh Ibn ‘Uthaymeen
