Anas bin Malik reported: (The people) stood up for the night prayer and a man stood up and spoke forth: Messenger of Allah, I have to say something to you. He (the Prophet) entered into secret conversation with him, till the people or some of the people dozed off, ad then he led them in prayer. He (Thabit al-Bunani) did not mention ablution.

Narrated Abdullah ibn Abbas: The Messenger of Allah ﷺ used to prostrate and sleep (in prostration) and produce puffing sounds (during sleep). Then he would stand and pray and would not perform ablution. I said to him: you prayed but did not perform ablution though you slept (in prostration). He replied: Ablution is necessary for one who sleeps while he is lying down. Uthman and Hannad added: For when he lies down, his joints are relaxed. Abu Dawud said: The statement "ablution is necessary for one who sleeps while one is lying down" is a munkar (rejected) tradition. It has been narrated only by Yazid Abu Khalid al-Dalani, on the authority of Qatadah. And its earlier part has been narrated by a group (of narrators) from Ibn Abbas; they did not mention anything about it. He (Ibn Abbas) said: The Prophet ﷺ was protected (during his sleep). Aishah reported: The Prophet ﷺ said: My eyes sleep, but my heart does not sleep. Shubah said: Qatadah heard from Abul-Aliyah only four traditions: the tradition about Jonah son of Matthew, the tradition reported by Ibn Umar about prayer, the tradition stating that the judges are three, and the tradition narrated by Ibn Abbas saying: (This tradition) has been narrated to me by reliable persons ; Umar is one of them, and the most reliable of them in my opinion is Umar. Abu Dawud said: I asked Ahmad bin Hanbal about the tradition narrated by Yazid al-Dalani. He rebuked me out of respect for him. Then he said: Yazid al-Dalani does not add anything to what has been narrated by the teachers of Qatadah. He did not care of this tradition (due to its weakness).

Narrated Ali ibn Abu Talib: The Messenger of Allah ﷺ said: The eyes are the leather strap of the anus, so one who sleeps should perform ablution.

Narrated Abdullah ibn Masud: We would not wash our feet after treading on something unclean, nor would we hold our hair and garments (during prayer). Abu Dawud said: The tradition has been reported by Ibrahim bin Abi Muawiyah through a different chain of narrators: Amash - Shaqiq - Masruq - Abdullah (bin Masud). And Hannad reported from Shaqiq, or reported on his authority saying: Abdullah (bin Masud) said.

Narrated Ali ibn Talq: The Messenger of Allah ﷺ said: When any of you breaks wind during the prayer, he should turn away and perform ablution and repeat the prayer.

Ali said: My prostatic fluid flowed excessively. I used to take a bath until my back cracked (because of frequent washing). I mentioned it to the prophet ﷺ, or the fact was mentioned to him (by someone else). The Messenger of Allah ﷺ said; Do not do so. When you find prostatic fluid, wash your penis and perform ablution as you do for your prayer, but when you have seminal emission, you should take a bath.

Narrated Al-Miqdad ibn al-Aswad: Ali ibn Abu Talib commanded him to ask the Messenger of Allah ﷺ what a man should do when he wants to have intercourse with his wife and the prostatic fluid comes out (at this moment). (He said): I am ashamed of consulting him because of the position of his daughter. Al-Miqdad said: I asked the Messenger of Allah ﷺ about it. He said: When any of you finds, he should wash his private part, and perform ablution as he does for prayer.

Urwah said: Ali b abi Talib said to al-miqdad, and made a similar statement as above. Al-Miqdad asked him (the prophet). The prophet ﷺ said: he should wash his penis and testicles. Abu Dawud said: The tradition has been narrators by al-Thawri and a group of narrators from Hisham on the authority of his father from al-Miqdad, from Ali reporting from the prophet ﷺ.

Urwah reported on the Authority of his father a tradition from Ali bin Abi Talib who said: I Asked al-Miqdad (to consult the prophet). He then narrated the tradition bearing the same meaning. Abu Dawud said; this tradition has been reported with another chain of narrators. This version does not mention the word “testicles”.

Narrated Sahl ibn Hunayf: I felt greatly distressed by the frequent flowing of prostatic fluid. For this reason I used to take a bath very often. I asked the Messenger of Allah ﷺ about this. He replied: Ablution will be sufficient for you because of this. I asked: Messenger of Allah, what should I do if it smears my clothes. He replied: It is sufficient if you take a handful of water and sprinkle it on your clothe when you find it has smeared it.
