It is narrated from Marwan bin Hakam that once I was present between Makkah and Madinah with Sayyiduna Uthman Ghani and Sayyiduna Ali (may Allah be pleased with them). Sayyiduna Uthman Ghani (may Allah be pleased with him) used to prohibit Hajj Tamattu', that is, combining Hajj and Umrah in the same journey. Seeing this, Sayyiduna Ali (may Allah be pleased with him) put on the Ihram for both. Sayyiduna Uthman (may Allah be pleased with him) said to him, "Are you not aware that I have issued the order prohibiting this, and yet you are still doing it?" He replied, "But I cannot leave the word of the Prophet (peace and blessings be upon him) for the word of anyone else."

Maisarah (may Allah have mercy on him) says that once I saw that Sayyiduna Ali (may Allah be pleased with him) drank water while standing. I said to him, "Are you drinking water while standing?" He replied, "If I have drunk water while standing, it is because I saw the Prophet (peace and blessings be upon him) do so, and if I have drunk while sitting, I have also seen him do it that way."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once Sayyidah Fatimah (may Allah be pleased with her) complained to the Prophet (peace and blessings be upon him) that marks had appeared on her hands from grinding flour. During this time, some captives had come to the Prophet (peace and blessings be upon him) from somewhere. When Sayyidah Fatimah (may Allah be pleased with her) found out, she came to the Prophet (peace and blessings be upon him) with a request for a servant, but did not find him. So she informed Sayyidah Aisha (may Allah be pleased with her) and returned. When the Prophet (peace and blessings be upon him) returned, Sayyidah Aisha (may Allah be pleased with her) informed him of Sayyidah Fatimah’s (may Allah be pleased with her) visit. So, at night, when we had already lain down on our beds, the Prophet (peace and blessings be upon him) came. We wanted to stand up, but he (peace and blessings be upon him) said:“Stay in your places.”Saying this, the Prophet (peace and blessings be upon him) sat down with us—so much so that I felt the coolness of his feet—and said:“Shall I not tell you something that is better for you than a servant? When you lie down on your bed, say Subhan Allah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-four times.”

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that a black 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 (hadd) 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 hadd on her. Remember! The prescribed punishments should also be carried out on your male and female slaves."

When Sayyiduna Ali (may Allah be pleased with him) would set out on a journey, he would keep traveling until the sun had set and darkness had fallen. Then he would dismount and perform the Maghrib prayer at its last time, and immediately after that, he would perform the Isha prayer at its earliest time. He would say that he had seen the Prophet (peace and blessings of Allah be upon him) do the same.

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

Syedna Ali (may Allah be pleased with him) narrates that when the Prophet (peace and blessings be upon him) sent me to Yemen, I was young at that time. I said to the Prophet (peace and blessings be upon him), "I am young and I have absolutely no knowledge of making judgments." The Prophet (peace and blessings be upon him) struck his hand on my chest and said: "Allah will guide your tongue to the right path and will keep your heart firm." Syedna Ali (may Allah be pleased with him) says that after that, I never had any doubt in making judgments between two people.

Saeed bin Musayyib (may Allah have mercy on him) narrates that once Sayyiduna Ali and Sayyiduna Uthman Ghani (may Allah be pleased with them both) met together at the place of Usfan. Sayyiduna Uthman (may Allah be pleased with him) used to prohibit Hajj Tamattu’. Sayyiduna Ali (may Allah be pleased with him) asked him,“What is your purpose in prohibiting something which the Prophet (peace and blessings be upon him) himself did?”Sayyiduna Uthman (may Allah be pleased with him) replied,“Let this matter be.”(Because I have not given a ruling on it, I have only mentioned it as advice.)

Sayyiduna Ali (may Allah be pleased with him) says that I never heard the Prophet (peace and blessings of Allah be upon him) combine his parents for anyone except Sayyiduna Sa’d (may Allah be pleased with him). On the day of the Battle of Uhud, the Prophet (peace and blessings of Allah 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 the Messenger of Allah (peace and blessings be upon him) said: "Sprinkling water over the urine of a boy is sufficient, and whatever the urine of a girl touches should be washed." Qatadah (may Allah have mercy on him) says that this ruling is until they begin to eat and drink, and when they start eating and drinking, then whatever either of their urine touches must be washed.
