It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to offer Witr in the early, middle, and last parts of the night, however, in the end, he (peace and blessings be upon him) became consistent in offering it in the last part of the night.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When a person remains seated on his prayer mat after the prayer, the angels send blessings upon him, and the angels’ blessing is this supplication: O Allah! Forgive him, O Allah! Have mercy on him. In the same way, if he sits waiting for the next prayer, the angels also send blessings upon him, and their blessing is this supplication: O Allah! Forgive him, O Allah! Have mercy on him."

Sayyiduna Ali (may Allah be pleased with him) says that Witr does not have definitive proof from the Noble Qur’an like the obligatory prayers, but its obligation is established from the Sunnah of the Prophet (peace and blessings be upon him).

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that on the day of the Battle of Khandaq, the Prophet (peace and blessings of Allah be upon him) said: "May Allah fill their (the polytheists') houses and graves with fire, for they did not let us perform the Asr prayer until the sun had set."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) decided that "the payment of the deceased's debt will be made before the execution and implementation of the will," whereas in the Qur'an, the mention of the will comes before the debt, and that "uterine brothers will be heirs but consanguine brothers will not be heirs." A person's full brother will be his heir, but a brother sharing only the father will not be an heir. Benefit: A brother sharing only the mother is called 'ukhiyafi' and a brother sharing only the father is called 'ilati'.

Nazzal bin Sabrah says that once after the Zuhr prayer, a jug of water was brought to Sayyiduna Ali (may Allah be pleased with him). He was in the courtyard of the mosque. He drank that water while standing and said: Some people consider this disliked, but I saw the Prophet (peace and blessings of Allah be upon him) doing it just as you have seen me doing it. Then he wiped with the remaining water and said: The person who is not without ablution, but already has ablution, this is the ablution of such a person.

Once, the mention of the Khawarij was made in the presence of Sayyiduna Ali (may Allah be pleased with him), so he said: Among them there will be a man who is deformed in creation. If you had not gone to extremes, I would have told you the promise that Allah has made, through the tongue of the Prophet (peace and blessings be upon him), to those who kill them. The narrator says: I asked him, "Did you really hear any statement from the Prophet (peace and blessings be upon him) regarding this?" He replied three times, "Yes! By the Lord of the Ka'bah."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "O people of the Qur'an! Perform Witr, for Allah is Odd and He loves the odd number."
