"Such of your women as have passed the age of monthly courses, for them the prescribed period, if ye have any doubts, is three months, and for those who have no courses (it is the same): for those who carry (life within their wombs), their period is until they deliver their burdens: and for those who fear Allah, He will make their path easy." - Quran 65:4 (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)

"...resembling animals is not something appropriate for the Muslim to do, because it is humiliating a soul that Allah has honoured with reason, and resembling animals is not mentioned in the Qur’aan or Sunnah except in the context of blame. If the [child's] costume of this animal is three-dimensional, it is not permissible because it comes under the heading of making images, which is forbidden in the texts. As for costumes resembling inanimate objects, there is nothing wrong with wearing them and using them." - Shaykh Dr. Ahmad ibn Muhammad al-Khudayri
