Narrated Abu Huraira: Allah's Apostle said, "No woman should ask for the divorce of her sister (Muslim) so as to take her place, but she should marry the man (without compelling him to divorce his other wife), for she will have nothing but what Allah has written for her."

Narrated Usama: Once while I was with the Prophet and Sa`d, Ubai bin Ka`b and Mu`adh were also sitting with him, there came to him a messenger from one of his daughters, telling him that her child was on the verge of death. The Prophet told the messenger to tell her, "It is for Allah what He takes, and it is for Allah what He gives, and everything has its fixed time (limit). So (she should) be patient and look for Allah's reward."

Narrated Abu Sa`id Al-Khudri: That while he was sitting with the Prophet a man from the Ansar came and said, "O Allah's Apostle! We get slave girls from the war captives and we love property; what do you think about coitus interruptus?" Allah's Apostle said, "Do you do that? It is better for you not to do it, for there is no soul which Allah has ordained to come into existence but will be created."

Narrated Hudhaifa: The Prophet once delivered a speech in front of us wherein he left nothing but mentioned (about) everything that would happen till the Hour. Some of us stored that our minds and some forgot it. (After that speech) I used to see events taking place (which had been referred to in that speech) but I had forgotten them (before their occurrence). Then I would recognize such events as a man recognizes another man who has been absent and then sees and recognizes him.

Narrated `Ali: While we were sitting with the Prophet who had a stick with which he was scraping the earth, he lowered his head and said, "There is none of you but has his place assigned either in the Fire or in Paradise." Thereupon a man from the people said, "Shall we not depend upon this, O Allah's Apostle?" The Prophet said, "No, but carry on and do your deeds, for everybody finds it easy to do such deeds (as will lead him to his place)." The Prophet then recited the Verse: 'As for him who gives (in charity) and keeps his duty to Allah..' (92.5)
