It is reported by Qays that Amr bin al-Aas (ra) was going somewhere with his friends. They saw a dead mule whose belly had swollen up. Amr (ra)said," By Allah, it is better for one to eat to his full from this (dead mule) than to eat the flesh of a Muslim" (He meant to say that to backbite anyone is worse than eating the meat of a dead animal).

‘Umar has come to me and told me that casualties were heavy at al-Yamamah among the Muslims who knew the Qur'an by heart, and I am afraid that more heavy casualties may take place among the Muslims who know the Qur'an by heart on other battlefields and a large part of the Qur’an may be lost. I ['Umar] think that you [Abu Bakr should issue instructions that the Qur'an be collected. I said to ‘Umar. How can I do anything that the Messenger of Allah (ﷺ) did not do? He said: By Allah, it is a good thing. And he kept urging me to do that until Allah opened my heart to it and I came around to 'Umar's point of view. Zaid said: And ‘Umar was sitting with him, not speaking. Abu Bakr said: You are a wise young man and we trust you. You used to write down the revelation for the Messenger of Allah (ﷺ), so collect it. Zaid said: By Allah, if they had ordered me to move a mountain, that would not have been more difficult for me than what they instructed me to do of collecting the Qur'an. I said: How can you do anything that the Messenger of Allah (ﷺ) did not do?

I asked `Ali (رضي الله عنه) about the nafl prayers of the Prophet (ﷺ) during the day. He said: You are not able for that. We said: Tell us and we will do as much of it as we can, He said: When the Messenger of Allah (ﷺ) prayed Fajr, he would wait until the sun would rise from there, meaning in the east, as high as it is at the time of `Asr there, meaning in the west. Then he would get up and pray two rak`ahs. Then he would wait until the sun rose as high there, meaning in the east, as it is at the time of Zuhr there, meaning in the west; then he would pray four rak`ahs, and four before Zuhr when the sun passed the meridian, and four afterwards, and four before ‘Asr, He would separate each two rak’ahs with salams upon the angels who are close to Allah, the Prophets, the believers and the Muslims who follow them. `Ali (رضي الله عنه) said: That is sixteen rak`ahs which the Prophet (ﷺ) offered as nafl prayers during the day, but there are very few who offer them regularly. Wakee’ narrated; my father said: Habeeb bin Abi Thabit said to Abu Ishaq when he narrated this to him: O Abu Ishaq, this hadeeth of yours is worth this mosque filled with gold.

Abu Hurayra said, "When someone spits in the presence of people, let him catch it with his palms so that his spit does not fall on the ground. When he fasts, he should oil his palm so that the trace of the fast is not seen on him."

“Allah’s Messenger said (Allah bless him and give him peace): 'Wear white, for it is most pure and pleasant, and you must shroud your deceased therein'.”

“Anas ibn Malik used to breathe into the vessel three times, and Anas ibn Malik maintained that the Prophet (Allah bless him and give him peace) likewise used to breathe into the vessel three times.”
