Abdu Khair (may Allah have mercy on him) says that once Syedna Ali (may Allah be pleased with him) taught us the way of ablution of the Prophet (peace and blessings be upon him) and said that the Prophet (peace and blessings be upon him) used to perform ablution in this manner. In this ablution, he washed each limb three times.

Sayyiduna Ali (may Allah be pleased with him) narrates that once the Prophet (peace and blessings be upon him) ordered Sayyiduna Ibn Mas’ud (may Allah be pleased with him), so he climbed a tree. The Prophet (peace and blessings be upon him) had instructed him to bring something. When the noble Companions (may Allah be pleased with them) saw Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) climbing the tree, their gaze fell upon his shins. Seeing his thin shins, they began to laugh. The Prophet (peace and blessings be upon him) said:“Why are you laughing? Indeed, Abdullah’s one leg will be heavier on the scale of deeds on the Day of Resurrection than the mountain of Uhud.”

On the day of the Battle of Jamal, Sayyiduna Ali (may Allah be pleased with him) said that regarding leadership, the Prophet (peace and blessings of Allah be upon him) did not give us any specific instruction that we should act upon; rather, it was a matter that we selected for ourselves. First, Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) became the caliph—may Allah's mercy descend upon him—he remained steadfast and established (the caliphate). Then Sayyiduna Umar Farooq (may Allah be pleased with him) became the caliph—may Allah's mercy descend upon him as well—he remained steadfast and established (the caliphate) until the religion laid its neck on the ground (i.e., it became firm and strong).

On one occasion, Sayyiduna Ali (may Allah be pleased with him) said: Shall I not tell you who is the best person in this Ummah after the Prophet (peace and blessings be upon him)? He is Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him), and after Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him), the best person in this Ummah is Sayyiduna Umar (may Allah be pleased with him). After that, Allah creates love wherever He wills.

Sayyiduna Ali and Sayyiduna Ibn Mas'ud (may Allah be pleased with them both) narrate that the Prophet (peace and blessings of Allah be upon him) gave a verdict regarding the right of neighborhood.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade me from wearing a gold ring, silk clothing, or a garment dyed with safflower, and from reciting the Noble Qur'an while in the state of bowing or prostration.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once three men came to the presence of the Messenger of Allah. One of them said: I had one hundred uqiyah, out of which I spent ten uqiyah in the way of Allah. The second said: I had one hundred dinars, out of which I spent ten dinars in the way of Allah. The third said: I had ten dinars, out of which I spent one dinar in the way of Allah. The Prophet (peace and blessings be upon him) said: "You are all equal in reward, because each of you has spent one tenth of his wealth."

On one occasion, Sayyiduna Ali (may Allah be pleased with him) stood up and said: In this Ummah, after the Prophet (peace and blessings be upon him), the best person is Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him) and Sayyiduna Umar al-Faruq (may Allah be pleased with him). After them, we have invented things in which Allah will decide as He wills.

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 once the Prophet (peace and blessings of Allah be upon him) washed each part of the body three times while performing ablution.
