The Prophet (saws) would take a bath because of sexual defilement on Friday, after opening a vein and after washing a dead body.

Samura b. Jundub reported God’s messenger as saying, “If anyone performs ablution on Friday, well and good; but if anyone bathes, bathing is more excellent.” Ahmad, Abu Dawud, Tirmidhi, Nasa’i and Darimi transmitted it.

after seminal defilement, on Friday, after being cupped, and after washing the dead. Abu Dawud transmitted it.

Ali, Fadl and Usamah ibn Zayd washed the Messenger of Allah (saws) and they put him in his grave. Marhab or Ibn AbuMarhab told me that they also made AbdurRahman ibn Awf join them.

When Ali became free, he said: The People of the man serve him.

She also reported God’s messenger as saying, “When the parts which are circumcised pass one another washing is necessary,” adding that God’s messenger and she did that, and then washed. Tirmidhi and Ibn Majah transmitted it.

Abu Huraira reported God’s messenger as saying, “Anyone who has washed a dead body must bathe himself.” Ibn Majah transmitted it; and Ahmad, Tirmidhi and Abu Dawud added, “And he who carries it must perform ablution.”

The Messenger of Allah (PBUH) said, "It suffices to perform Wudu' properly for the Friday prayer; but it is better to take a bath."

[Abu Dawud and At-Tirmidhi].

Yahya related to me from Malik from Damra ibn Said al-Mazini from Aban ibn Uthman that Uthman ibn Affan ate bread and meat, rinsed his mouth out, washed his hands and wiped his face with them, and then prayed without doing wudu.

Yahya related to me from Malik from Nafi that Abdullah ibn Umar, if he wished to sleep or eat while junub, would wash his face, and his arms to the elbows, and wipe his head. Then he would eat or sleep.

2.20 The Repetition of the Prayer by a Person in a State of Major Ritual Impurity, his Doing Ghusl, when He has Prayed without Remembering it, and his Washing his Garments.

Yahya related to me from Malik from Safwan ibn Sulaym from Ata ibn Yasar from Abu Said al-Khudri that the Messenger of Allah, may Allah bless him and grant him peace, said, "Ghusl on the day of jumua is incumbent on every male who has reached puberty."

"I suffered from a severe and troubling case of Al-Madhi. I was performing Ghusl often because of it. So I mentioned that to Allah's Messenger and asked him about it. He said: "You only need to perform Wudu for that." I said: "O Messenger of Allah! How about when it gets on my clothes?" He said: "It is sufficient for you to take a handful of water and sprinkle it n your garment wherever you see that it has touched it."

I did ‘Umrah with ‘Ali bin Abi Talib (رضي الله عنه) at the time of `Umar - or at the time of `Uthman. He stayed with his sister Umm Hani` bint Abi Talib, and when he had finished his ‘Umrah he went back, and water was prepared for him and he washed himself. When he had finished washing himself, some of the people of Iraq entered upon him and said: O, Abu Hasan, we have come to you to ask you about something we would like you to tell us about, He said: I think Al-Mugheerah bin Shu`bah is telling you that he was the last of the people to speak to the Messenger of Allah (ﷺ). They said: Yes, we have come to ask you about that. He said: The last of the people to speak to the Messenger of Allah (ﷺ) was Qutham bin al-Abbas.

‘Ikrima said that some people from al-‘Iraq came and asked Ibn ‘Abbas whether he considered bathing on Friday obligatory. He replied that, while not obligatory, it had a more cleansing effect and was better for the one who observed it; but if anyone did not bathe there was no obligation for him to do so. He then said that he would tell them how the practice of bathing on Friday began. The people were in difficult circumstances, their clothing being of wool and their work being the carrying of loads on their backs. Their mosques was rather small and had a low roof which was only made of trellis work. God’s messenger came out one hot day when the people were sweating in their woollen garments to such an extent that they annoyed one another by the odours which were spread around. When God’s messenger noticed those odours he said, “When this day comes, you people must wash, and each of you should apply the best grease and perfume you can find.” Ibn ‘Abbas added that when God afterwards brought prosperity, they wore clothes not made of wool, they did not need to do manual labour, their mosque was extended, and some of the annoyance caused to one another by the sweat came to an end. Abu Dawud transmitted it.

He wiped his head with water which was not what was left over after washing his hands (i.e. he wiped his head with clean water); then he washed his feet until he cleansed them.

The Prophet (PBUH) instructed us at the time of washing the dead body of his daughter Zainab (May Allah be pleased with her) to begin with her right side, and from the parts that are washed in Wudu'.

[Al-Bukhari and Muslim].

Sulaiman b. Yasir said that he asked ‘A’isha about the prostatic fluid which gets on to a garment, and she replied, “I used to wash it from the garment at God's messenger, and he would go out to prayer with the mark of the washing on his garment." (Bukhari and Muslim.)

I saw ‘ Uthman b. ‘ Affan (perform ablution). He washed his forearms three times and washed his head thrice. He then said : I saw the Messenger of Allah (saws) doing like that.

Abu Dawud said: Another version says: "He performed ablution three times only."

Abu Huraira said that he heard his friend Abul Qasim (. i.e. the Prophet) say, “The prayer of a woman who has perfumed herself to go to the mosque is not accepted till she bathes as she would for sexual defilement.” Abu Dawud transmitted it, and Ahmad and Nasa’i transmitted something similar.

Uthman (rad) called for water to perform ablution. He washed palms of his hands three times, then rinsed his mouth and sniffed water in his nose and then blew it out. He then washed his face three times. Thereafter he washed his right hand up to his elbow three times, then the left one likewise, then he passed wet hands on his head. Then he washed his right foot up to the ankle three times, then the left one likewise. He then said, “I saw Allah’s Messenger (saw) performing ablution like this ablution of mine”. [Agreed upon]

he wiped his head so much so that drops (of water) were about to trickle down. He then washed his feet three times and said: This is how the Messenger of Allah (saws) performed ablutions.

I saw ‘Ali perform ablution. He (Abu Hayyah) then described that ‘Ali went through every part of the ablution three times, i.e. he performed each detail of his ablution three times. He then wiped his head, then washed his feet up to the ankles. He then said: I wanted to show you how the Messenger of Allah (saws) performed ablution.

One day the Messenger of Allah (May peace be upon him) had sexual intercourse with (all) his wives with a single bath.

Abu Dawud said: This tradition has been transmitted through another chain of narrators.

'Aishah said; When the Messenger of Allah (May peace be upon him) intended to take a bath because of sexual defilement, he would begin with his hands and wash them. Then he would wash the joints of his limbs and pour water upon him when he cleansed both his (hands), he would rub them on the wall (to make them perfectly clean with the dust). Then he would perform ablution and pour water over his head.

I asked the Messenger of Allah (saws) as to what makes it necessary to take a bath and about the (prostatic) fluid that flows after taking a bath. He replied: that is called madhi (prostatic fluid). It flows from every male. You should wash your private parts and testicles because of it and perform ablution as you do for prayer.
