It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that a man asked the Messenger of Allah (peace and blessings be upon him): "O Messenger of Allah! We travel by sea and carry only a little water with us. If we use it for ablution, we will be left thirsty. May we perform ablution with the water of the sea?" The Messenger of Allah (peace and blessings be upon him) replied: "Its (the sea's) water is pure and its dead (fish) is lawful."

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) ate the (roasted) meat of a goat’s shoulder, then he prayed and did not perform ablution (again).

It is narrated from Sayyiduna Miqdad bin Aswad (may Allah be pleased with him) that Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) instructed him to ask the Messenger of Allah (peace and blessings be upon him) about a man who, when he goes to his wife, experiences the emission of madhi (pre-seminal fluid); what is obligatory upon such a man? Sayyiduna Ali (may Allah be pleased with him) said: Because the daughter of the Messenger of Allah (peace and blessings be upon him) is my wife, I feel shy to ask the Messenger of Allah (peace and blessings be upon him) about this issue. Miqdad (may Allah be pleased with him) said: So I asked the Messenger of Allah (peace and blessings be upon him) about it, and he said: "If any of you experiences such a condition, he should wash his private part with water and perform wudu for prayer."

It is narrated from Urwah bin Zubair (may Allah have mercy on him) that I went to Marwan bin Al-Hakam (the Umayyad), and we discussed what things make ablution (wudu) necessary. Marwan said: Touching the private part (penis) makes ablution necessary. Urwah said: I do not know about this. Marwan said: Busrah bint Safwan (may Allah be pleased with her) informed me that she heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "When any one of you touches his private part, he should perform ablution."

It is narrated from Sayyiduna Suwaid bin Nu'man (may Allah be pleased with him) that he went with the Messenger of Allah (peace and blessings be upon him) in the year of Khaybar, until when they reached a place near Khaybar called Al-Sahba, the Messenger of Allah (peace and blessings be upon him) performed the Asr prayer. Then provisions for the journey were requested, but nothing was found except sattu (parched barley meal). So the Prophet (peace and blessings be upon him) ordered that it be soaked in water, then he and we ate it. When he stood up for the Maghrib prayer, he rinsed his mouth and we also rinsed our mouths, then he led us in prayer and did not perform ablution again.

It is narrated from the wife of the Prophet, Sayyida Aisha (may Allah be pleased with her), that we set out with the Messenger of Allah (peace and blessings be upon him) on a journey until we reached the place of Baida or Dhat al-Jaish, when my necklace broke and fell. The Messenger of Allah (peace and blessings be upon him) and his companions stopped to look for it, and there was no water there, nor did the people have any water. The people went to Abu Bakr al-Siddiq (may Allah be pleased with him) and said: Do you not see what Aisha has done? She has held up the Messenger of Allah (peace and blessings be upon him) and the people, and there is no water here, nor do the people have any water. Then Sayyiduna Abu Bakr (may Allah be pleased with him) came, and the Messenger of Allah (peace and blessings be upon him) was resting his head on my thigh and sleeping. He said: You have held up the Messenger of Allah (peace and blessings be upon him) and the people, and there is no water here, nor do the people have any water. Then (my father) Sayyiduna Abu Bakr (may Allah be pleased with him) reproached me and said what Allah willed, and he was poking his hand into my side, and I could not move because of the Messenger of Allah (peace and blessings be upon him), as he was resting his head on my thigh and sleeping. The Messenger of Allah (peace and blessings be upon him) slept until morning, and no water was found until morning. Then Allah revealed the verse of tayammum: «فَتَيَمَّمُوا صَعِيدًا طَيِّبًا» "So perform tayammum with clean earth." [النساء: 43، المائده: 6] Then Sayyiduna Usayd ibn Hudayr (may Allah be pleased with him) said (happily): O family of Abu Bakr! This is not your first blessing. Then we raised the camel on which I was riding, and my necklace was found underneath it.
