It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) forbade the recitation of the Noble Qur'an while in the state of bowing (ruku') or prostration (sujud).

Sayyiduna Ali (may Allah be pleased with him) narrates that I once submitted in the presence of the Messenger of Allah (peace and blessings be upon him), "O Messenger of Allah! Why do you prefer other families of Quraysh over us?" The Prophet (peace and blessings be upon him) said, "Do you also have something (to offer)?" I replied, "Yes! The daughter of Sayyiduna Hamza (may Allah be pleased with him)!" So the Prophet (peace and blessings be upon him) said, "She is not lawful for me because she is my foster niece." (In fact, the Prophet (peace and blessings be upon him) and Sayyiduna Amir Hamza were foster brothers as well as uncle and nephew to each other.)

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that one day the Prophet (peace and blessings be upon him) was sitting, and in his blessed hand was a stick with which he was scratching the ground. After a short while, he raised his head and said: "The abode of every one of you, whether in Paradise or Hell, is already known and determined by Allah." The noble companions (may Allah be pleased with them) asked: "O Messenger of Allah! Then why should we act?" He said: "Continue to act, for each person will find it easy to do the deeds for which he was created." Then the Prophet (peace and blessings be upon him) recited this verse of the Qur'an: "So as for he who gives, fears Allah, and affirms the best (truth), We will ease him toward ease. But as for he who withholds, considers himself free of need, and denies the best (truth), We will ease him toward difficulty."

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. When they set out, that Ansari became angry with them over something and said to them, "Gather firewood." After that, he had a fire lit in the wood and said, "I make you swear that you must enter this fire." The people were just considering jumping into it when a young man said, "It was from this very fire that you fled and sought refuge with the Prophet (peace and blessings be upon him). Do not be hasty; first go and ask the Prophet (peace and blessings be upon him). If he commands you to jump into it, then certainly do so." So the people stopped and, upon returning, 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."

Waqid bin Amr says that I was present at a funeral of someone from Banu Salamah. When I saw the funeral, I stood up. Nafi’ bin Jubair said to me,“Sit down, I will tell you something strong regarding this matter. Mas’ud bin Hakam told me that he heard Sayyiduna Ali (may Allah be pleased with him) in the courtyard of the Kufa mosque saying that the Messenger of Allah (peace and blessings be upon him) used to order us to stand upon seeing a funeral, but later he himself started sitting and ordered us to sit as well.”

Abu Sasan Raqashi says that some people from Kufa came to the service of Sayyiduna Uthman Ghani (may Allah be pleased with him) and they informed Sayyiduna Uthman (may Allah be pleased with him) about some news regarding Walid's drinking of alcohol. Sayyiduna Ali (may Allah be pleased with him) also spoke to them about this matter, so Sayyiduna Uthman (may Allah be pleased with him) said to him, "Your cousin is in your charge, you carry out the punishment on him." He said to Sayyiduna Hasan (may Allah be pleased with him), "Hasan! Stand up and lash him." He said, "You cannot do this work, assign it to someone else." He said, "Actually, you have become weak and helpless, 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 lashing 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 now. The Prophet (peace and blessings be upon him) gave forty lashes to the one who drank alcohol, Sayyiduna Abu Bakr (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."

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that once Sayyiduna Ali (may Allah be pleased with him) came to my house. He asked for water for ablution. We brought him a bowl in which there was about a mudd or close to it of water, and placed it before him. At that time, he had finished relieving himself. He said to me: O Ibn Abbas! Shall I not show you how the Prophet (peace and blessings be upon him) performed ablution? I said: Why not? May my parents be sacrificed for you. So, a vessel was placed for his ablution. First, he washed both hands, rinsed his mouth, put water into his nose and cleaned it, then took water in both hands and wiped it over his face, and with his thumb, he put water on the front part of his ears, and did this three times. Then, with his right hand, he took a handful of water and poured it on his forehead so that it would flow over his face. Then he washed his right arm up to and including the elbow three times, and washed his left arm in the same way, wiped his head and ears, then took water in both hands and poured it over his feet, while he was wearing shoes. Then he moved the shoe and did the same with the other foot. I asked: Is ablution valid while wearing shoes? He replied: Yes, it is valid. This question and answer happened three times.

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 do not go to extremes, I will tell 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?" So 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) used to teach us the Noble Qur'an, provided that we were not in need of a ritual bath (ghusl) by choice.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once I submitted in the presence of the Messenger (peace be upon him), "When you send me somewhere, should I go as a molded coin (i.e., strictly following instructions) or should I make decisions after observing the circumstances there, because the person present at the scene sees what the absent one does not see?" He replied: "Rather, keep this in mind that the person present at the scene sees what the absent one does not see (and make decisions after observing the circumstances)."
