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)

Narrated Abu Huraira: We witnessed along with Allah's Apostle the Khaibar (campaign). Allah's Apostle told his companions about a man who claimed to be a Muslim, "This man is from the people of the Fire." When the battle started, the man fought very bravely and received a great number of wounds and got crippled. On that, a man from among the companions of the Prophet came and said, "O Allah's Apostle! Do you know what the man you described as of the people of the Fire has done? He has fought very bravely for Allah's Cause and he has received many wounds." The Prophet said, "But he is indeed one of the people of the Fire." Some of the Muslims were about to have some doubt about that statement. So while the man was in that state, the pain caused by the wounds troubled him so much that he put his hand into his quiver and took out an arrow and committed suicide with it. Off went some men from among the Muslims to Allah's Apostle and said, "O Allah's Apostle! Allah has made your statement true. So-and-so has committed suicide." Allah's Apostle said, "O Bilal! Get up and announce in public: None will enter Paradise but a believer, and Allah may support this religion (Islam) with a wicked man."

Narrated Sahl bin Sa`d: There was a man who fought most bravely of all the Muslims on behalf of the Muslims in a battle (Ghazwa) in the company of the Prophet. The Prophet looked at him and said. "If anyone would like to see a man from the people of the Fire, let him look at this (brave man)." On that, a man from the People (Muslims) followed him, and he was in that state i.e., fighting fiercely against the pagans till he was wounded, and then he hastened to end his life by placing his sword between his breasts (and pressed it with great force) till it came out between his shoulders. Then the man (who was watching that person) went quickly to the Prophet and said, "I testify that you are Allah's Apostle!" The Prophet asked him, "Why do you say that?" He said, "You said about so-and-so, 'If anyone would like to see a man from the people of the Fire, he should look at him.' He fought most bravely of all of us on behalf of the Muslims and I knew that he would not die as a Muslim (Martyr). So when he got wounded, he hastened to die and committed suicide." There-upon the Prophet said, "A man may do the deeds of the people of the Fire while in fact he is one of the people of Paradise, and he may do the deeds of the people of Paradise while in fact he belongs to the people of Fire, and verily, (the rewards of) the deeds are decided by the last actions (deeds)".

Narrated Ibn `Umar: The Prophet forbade vowing and said, "In fact, vowing does not prevent anything, but it makes a miser to spend his property."

Narrated Abu Huraira: The Prophet said (that Allah said), "Vowing does not bring to the son of Adam anything I have not already written in his fate, but vowing is imposed on him by way of fore ordainment. Through vowing I make a miser spend of his wealth."

Narrated Abu Musa: While we were with Allah's Apostle in a holy battle, we never went up a hill or reached its peak or went down a valley but raised our voices with Takbir. Allah's Apostle came close to us and said, "O people! Don't exert yourselves, for you do not call a deaf or an absent one, but you call the All- Listener, the All-Seer." The Prophet then said, "O `Abdullah bin Qais! Shall I teach you a sentence which is from the treasures of Paradise? ( It is): 'La haula wala quwata illa billah. (There is neither might nor power except with Allah).

Narrated Abu Sa`id Al-Khudri: That the Prophet said, "No Caliph is appointed but has two groups of advisors: One group advises him to do good and urges him to adopt it, and the other group advises him to do bad and urges him to adopt it; and the protected is the one whom Allah protects."
