"They ask you concerning menstruation, Say: that is an Adha (a harmful thing for a husband to have a sexual intercourse with his wife while she is having her menses), therefore keep away from women during menses and go not unto them till they have purified (from menses and have taken a bath), And when they have purified themselves, then go in unto them as Allaah has ordained for you (go in unto them in any manner as long as it is in their vagina), Truly, Allaah loves those who turn unto Him in repentance and loves those who purify themselves (by taking a bath and cleaning and washing thoroughly their private parts, bodies, for their prayers, etc.)." [Al-Baqarah (2):222]

Narrated Zaid bin Khalid Al-Juhani:

A man asked the Prophet about the picking up of a "Luqata" (fallen lost thing). The Prophet replied, "Recognize and remember its tying material and its container, and make public announcement (about it) for one year, then utilize it but give it to its owner if he comes." Then the person asked about the lost camel. On that, the Prophet got angry and his cheeks or his Face became red and he said, "You have no concern with it as it has its water container, and its feet and it will reach water, and eat (the leaves) of trees till its owner finds it." The man then asked about the lost sheep. The Prophet replied, "It is either for you, for your brother (another person) or for the wolf." [The Book of Knowledge Volume 1, Book 3, Hadeeth 91]
