It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade anyone from raising his voice while reciting (the Qur'an) between Maghrib and Isha.

Ali bin Rabi’ah says that I once saw Sayyiduna Ali (may Allah be pleased with him) that a riding animal was brought to him for him to mount. When he placed his foot in its stirrup, he said“Bismillah”(In the name of Allah). When he sat on it, he recited this supplication: «اَلْحَمْدُ لِلّٰهِ سُبْحَانَ الَّذِي سَخَّرَ لَنَا هَذَا وَمَا كُنَّا لَهُ مُقْرِنِينَ وَإِنَّا إِلَى رَبِّنَا لَمُنْقَلِبُونَ» “All praise is for Allah. Glory be to Him Who has subjected this (animal) to us, for we could not have subdued it (by ourselves), and surely to our Lord we are returning.”Then he said“Alhamdulillah”(All praise is for Allah) three times and“Allahu Akbar”(Allah is the Greatest) three times, and then said: «سُبْحَانَكَ لَا إِلٰهَ إِلَّا أَنْتَ قَدْ ظَلَمْتُ نَفْسِي فَاغْفِرْ لِي» “O Allah! You are pure, there is no deity except You. I have wronged myself, so forgive me.”Then he smiled. I asked,“O Commander of the Faithful! What made you smile at this moment?”He replied,“I saw the Prophet (peace and blessings be upon him) do as I have done, and he also smiled. I asked him the reason, and he (peace and blessings be upon him) said, ‘When the servant says: O Lord! Forgive me, the Lord is pleased and says: My servant knows that none forgives sins except Me.’”

Abdullah bin Yasar says that once Amr bin Harith came to visit Sayyiduna Imam Hasan (may Allah be pleased with him) during his illness. Sayyiduna Ali (may Allah be pleased with him) said to him: "You have come to visit Hasan in his illness, but what about that which you are hiding in your heart?" Amr said: "You are not my Lord that you may do as you wish with my heart." Sayyiduna Ali (may Allah be pleased with him) said: "Even so, we will not refrain from advising you. I heard the Prophet (peace and blessings be upon him) say: 'When a Muslim visits his sick Muslim brother, Allah appoints seventy thousand angels for him who pray for his forgiveness every moment of the day until evening, and if he goes in the evening, they pray for him every moment of the night until morning.'"

Amr bin Harith asked: "What is your opinion about walking with a funeral? Should one walk in front of the funeral or behind it?" He replied: "Walking behind the funeral is superior to walking in front of it, just as the virtue of offering obligatory prayer in congregation is superior to offering it alone." Amr said: "But I myself have seen Sayyiduna Abu Bakr Siddiq and Sayyiduna Umar Farooq (may Allah be pleased with them both) walking in front of the funeral." He replied: "Both of them did not want to cause hardship to the people because of themselves."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that once a silk garment was sent as a gift to the Prophet (peace and blessings be upon him) from somewhere. The Prophet (peace and blessings be upon him) sent it to me. I wore it and went outside, but when I saw signs of displeasure on the blessed face of the Prophet (peace and blessings be upon him), I distributed it among my women.

Abdullah bin Shaqiq (may Allah have mercy on him) says that Sayyiduna Uthman Ghani (may Allah be pleased with him) used to prevent people from performing Hajj Tamattu', and Sayyiduna Ali (may Allah be pleased with him) used to give the fatwa of its permissibility. On one occasion, Sayyiduna Uthman (may Allah be pleased with him) must have said something to him, so Sayyiduna Ali (may Allah be pleased with him) said: "Do you even know that we performed Hajj Tamattu' with the Prophet (peace and blessings be upon him), yet you prevent it?" Sayyiduna Uthman (may Allah be pleased with him) said: "What you say is correct, but we fear (that people will go to their wives at night and in the morning will be wet from the water of janabah bath and will enter into the state of ihram for Hajj)."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said regarding an infant boy: "Sprinkling water over the urine of a boy is sufficient, and if a girl's urine gets on something, it should be washed." Qatadah says that this ruling is until they start eating and drinking, and when they start eating and drinking, then whatever their urine touches must be washed in both cases.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "No person can be a complete believer until he believes in four things: he bears witness that there is no deity except Allah, and that I am the Messenger of Allah, He has sent me as a true Prophet, he believes in being raised after death, and he believes in destiny."

Once, Sayyiduna Ali (may Allah be pleased with him) came to the service of the Prophet (peace and blessings be upon him) and informed him of the death of Abu Talib. The Prophet (peace and blessings be upon him) said: "Go and hide him in a pit." Sayyiduna Ali (may Allah be pleased with him) submitted that he died in a state of polytheism (how can I lower him into the grave?). The Prophet (peace and blessings be upon him) again said: "Go and hide him in a pit." When I had lowered him into a pit and returned to the Prophet (peace and blessings be upon him), he said to me: "Go and take a bath."

Sayyiduna Ali (may Allah be pleased with him) narrates that the Prophet (peace and blessings of Allah be upon him) once ordered me to sell two slaves; they were brothers to each other. I sold them to two different men, and then came and informed the Prophet (peace and blessings of Allah be upon him) about it. The Prophet (peace and blessings of Allah be upon him) said: "Go back and return them, and sell both of them together to one man." (So that there remains some closeness and affection between them.)

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).
