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."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once, at night, when we had already lain down on our beds, the Prophet (peace and blessings be upon him) came, placed his blessed feet between me and Fatimah, and taught us to recite these words after lying down on the bed: "Say Subhan Allah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-four times." Sayyiduna Ali (may Allah be pleased with him) says that after that, I never abandoned these words. Someone asked: Not even on the night of Siffin? He replied: Yes! (not even then).

Huzain (may Allah have mercy on him) says that once Walid bin Uqbah led the people in the Fajr prayer and performed four rak'ahs instead of two. Then he turned to the people and said, "Perhaps I have increased the number of rak'ahs in the prayer?" This matter was presented before Sayyiduna Uthman Ghani (may Allah be pleased with him), so he ordered the punishment for drinking wine to be carried out on Walid. Sayyiduna Ali (may Allah be pleased with him) said to Sayyiduna Imam Hasan (may Allah be pleased with him), "Hasan! Stand up and flog him." He said, "You cannot do this; order someone else to do it." He replied, "In reality, you have become weak and incapable, so Abdullah bin Ja'far! You stand up and carry out the punishment on him." Thus, Sayyiduna Abdullah bin Ja'far (may Allah be pleased with him) kept flogging him and Sayyiduna Ali (may Allah be pleased with him) kept counting. When forty lashes were completed, Sayyiduna Ali (may Allah be pleased with him) said, "Stop. The Prophet (peace and blessings of Allah be upon him) gave forty lashes to the one who drank wine, and Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) also gave forty lashes, but Sayyiduna Umar (may Allah be pleased with him) gave eighty lashes, and both are Sunnah."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that a maidservant of the Prophet (peace and blessings be upon him) committed the sin of adultery. The Prophet (peace and blessings be upon him) ordered me to carry out the prescribed punishment on her. I saw that her bleeding would not stop, so I came and mentioned this to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: "When her bleeding stops, then carry out the prescribed punishment on her. And remember! Carry out the prescribed punishments on your male and female slaves as well."

Sayyiduna Ali (may Allah be pleased with him) said 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). Therefore, O people of the Qur’an! Perform Witr.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I have exempted you from paying zakat on horses and slaves, therefore you must pay zakat on silver in any case. Its nisab is that for every forty, one dirham will be obligatory. Nothing will be obligatory up to one hundred and ninety dirhams, but when their number reaches two hundred, then five dirhams will be obligatory on it."

Asim bin Damrah reports that once a person asked Sayyiduna Ali (may Allah be pleased with him) how the Prophet (peace and blessings be upon him) used to perform voluntary prayers (nawafil). He replied that during the whole night, the Prophet (peace and blessings be upon him) would perform sixteen rak‘ahs of voluntary prayers.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once Chosroes sent a gift to the Prophet (peace and blessings be upon him), and he (peace be upon him) accepted it. Similarly, Caesar sent a gift and he (peace and blessings be upon him) accepted it as well, and when other kings sent gifts, he (peace and blessings be upon him) accepted those too.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) initially forbade visiting graveyards, using specific utensils, and keeping the meat of sacrificial animals for more than three days. Afterwards, he said: "Previously, I forbade you from visiting graveyards, now I permit you, so visit the graveyards, for it reminds one of the Hereafter. I also forbade you from using specific utensils, now you may use them for drinking, but avoid intoxicating things. And I forbade you from keeping the meat of sacrificial animals for more than three days, now you are permitted to keep it for as long as you wish."

The previous hadith is also narrated through this second chain of transmission.
