Sayyiduna Ali (may Allah be pleased with him) said: I used to have a lot of madhi (pre-seminal fluid). Since the daughter of the Prophet (peace and blessings be upon him) was in my marriage, I felt shy to ask the Prophet (peace and blessings be upon him) about this issue myself. So I said to Sayyiduna Miqdad (may Allah be pleased with him) to ask the Prophet (peace and blessings be upon him) about this issue. So he asked about this issue, and the Prophet (peace and blessings be upon him) said: "Such a person should wash his private part and perform wudu."

Syedna Ali (may Allah be pleased with him) said to Syedna Miqdad (may Allah be pleased with him) to ask the Prophet (peace and blessings be upon him) about the ruling of madhi (pre-seminal fluid), so the Prophet (peace and blessings be upon him) said: "Such a person should perform ablution (wudu)."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him), after relieving himself, would come out without performing ablution and begin reciting the Noble Qur'an. He (peace and blessings be upon him) would also eat meat with us, and nothing except major ritual impurity (janabah) would prevent him from reciting the Qur'an.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) used to pray two units of prayer after every obligatory prayer except Fajr and Asr.

Sayyiduna Ali (may Allah be pleased with him) said: My opinion was that for wiping over the leather socks (khuffayn), the part of the socks that touches the ground was more appropriate to wipe than the part that is on top of the foot, until I saw the Prophet (peace and blessings of Allah be upon him) wiping over the upper part, so I abandoned my opinion.

Abdu Khair, may Allah have mercy on him, says that I once saw Sayyiduna Ali, may Allah be pleased with him, performing ablution. He washed the upper part of his foot and said: If I had not seen the Prophet, peace and blessings be upon him, washing the upper part of his foot, my opinion would have been that the lower part of the foot is more deserving of being washed (because it touches the ground more).

The previous hadith is also narrated through this second chain, in which it is mentioned that I saw Sayyiduna Ali (may Allah be pleased with him) performing ablution, and he wiped over the upper part of his feet.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once, while performing ablution, the Prophet (peace and blessings be upon him) washed each of his limbs three times.

Sayyiduna Ali (may Allah be pleased with him) says that I never heard the Prophet (peace and blessings be upon him) combine his parents for anyone—except for Sayyiduna Sa’d (may Allah be pleased with him). On the day of the Battle of Uhud, the Prophet (peace and blessings be upon him) was saying to Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him):“Sa’d! Shoot the arrow, may my parents be sacrificed for you.”

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) sent out an army and appointed an Ansari as their commander, and ordered the people to listen to him and obey him. When they set out, that Ansari became angry with them over something along the way. He said, "Gather firewood." Then he had a fire lit in the wood and said, "Did the Prophet (peace and blessings be upon him) not order you to listen to me and obey me?" The people said, "Of course." He said, "Then enter this fire." The people began to look at one another and said, "It is from this very fire that we have fled and sought refuge with the Prophet (peace and blessings be upon him)." After a short while, his anger subsided and the fire was extinguished. When they returned, they told the Prophet (peace and blessings be upon him) the whole incident. The Prophet (peace and blessings be upon him) said, "If you had entered it once, you would never have come out of it. Remember! Obedience is only in matters of goodness."
