Lady Umm Salamah’s (may Allah be pleased with her) daughter, Lady Zainab (may Allah be pleased with her), narrates this statement from her mother, Lady Umm Salamah (may Allah be pleased with her): Lady Umm Sulaim (may Allah be pleased with her), who is the wife of Sayyiduna Abu Talha Ansari (may Allah be pleased with him), came to the service of the Prophet (peace and blessings be upon him). She said: O Messenger of Allah! Indeed, Allah does not shy away from the truth. If a woman experiences a wet dream, is ghusl (ritual bath) obligatory upon her? The Prophet (peace and blessings be upon him) said: Yes, if she sees water (i.e., if her semen is discharged).

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings of Allah be upon him): "Water (i.e., ghusl) becomes obligatory because of the emission of water (i.e., semen)."

Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) narrates: Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) informed me of this. He says: I asked, "O Messenger of Allah! A man goes to his wife (i.e., has intercourse with her) and he does not ejaculate." The Prophet (peace and blessings be upon him) said: "The woman should wash the moisture that has touched her and perform ablution, then offer prayer."

Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) narrates from Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) regarding the Prophet Muhammad (peace and blessings be upon him). Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) asked: What is your opinion about this matter—if a person has intercourse with his wife but does not ejaculate? The Prophet Muhammad (peace and blessings be upon him) said: He should wash his private part and his testicles, perform ablution, and then offer prayer.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: One day we were walking with the Prophet (peace and blessings of Allah be upon him) when he passed by the house of an Ansari (may Allah be pleased with him). The Prophet (peace and blessings of Allah be upon him) said: Where is so-and-so? The narrator says, then the Prophet (peace and blessings of Allah be upon him) called for him, and that person quickly came out from inside, with water dripping from his head. The Prophet (peace and blessings of Allah be upon him) said: Perhaps we forced you to hurry because of your need. That person said: Yes, by Allah! O Messenger of Allah, I had to hurry. So the Prophet (peace and blessings of Allah be upon him) said: If someone has to do something quickly or is short on time, then ghusl is not obligatory upon him. In that case, performing wudu is obligatory.

Zaid bin Khalid narrates: He asked Sayyiduna Uthman Ghani (may Allah be pleased with him) about a person who has intercourse but does not ejaculate. Sayyiduna Uthman (may Allah be pleased with him) replied that such a person is not required to perform ghusl (ritual bath). Then Sayyiduna Uthman (may Allah be pleased with him) said: I heard this from the Messenger of Allah (peace and blessings be upon him) himself. The narrator states: Later, I asked Sayyiduna Ali bin Abi Talib, Sayyiduna Zubair bin Al-Awwam, Sayyiduna Talha bin Ubaidullah, and Sayyiduna Ubayy bin Ka'b (may Allah be pleased with them), and they also gave a similar answer. The narrator named Abu Salamah states: Urwah bin Zubair informed me that he asked Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) about this matter, and he also narrated a similar statement from the Messenger of Allah (peace and blessings be upon him).

Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates: In the beginning of Islam, there was a concession regarding "water for water" (i.e., the ruling that ghusl is obligatory only upon the emission of semen), then this was prohibited. (Imam Ibn Hibban, may Allah have mercy on him, says:) This narration has been transmitted by Mu'ammar from Zuhri, which has been narrated by Ghundar. He says: Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) narrated this hadith to me. The same narration has been transmitted by 'Amr bin Khalid from Zuhri. In it, he says: A person whom I am pleased with narrated this hadith to me, and he narrated it from Sayyiduna Sahl bin Sa'd. So, it is possible that Zuhri himself heard this narration from Sayyiduna Sahl bin Sa'd, as Ghundar has stated, and Zuhri may have heard this narration from a person whom he was pleased with, and that person narrated it from Sayyiduna Sahl bin Sa'd. So, once he narrated it directly from Sayyiduna Sahl bin Sa'd, and another time he narrated it from the person whom he was pleased with, from Sayyiduna Sahl bin Sa'd. I investigated the chains of this narration to find if there was anyone who narrated this narration from Sayyiduna Sahl bin Sa'd, but I did not find anyone in the world except Abu Hazim. So, it is possible that the person about whom Zuhri said: "A person whom I am pleased with narrated this hadith to me," he narrated this hadith from Sayyiduna Sahl bin Sa'd, and that person is Abu Hazim, who narrated this narration from Sayyiduna Sahl.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Prophet (peace and blessings of Allah be upon him): "When a man sits between the four parts of a woman and then has intercourse with her, ghusl (ritual bath) becomes obligatory upon him."

It is narrated about Sayyida Aisha Siddiqa (may Allah be pleased with her) that she was asked about a person who has intercourse but does not ejaculate. Sayyida Aisha (may Allah be pleased with her) replied: The Prophet (peace and blessings be upon him) and I used to do so, but we both would perform ghusl (ritual bath) in that case.

Lady Aisha Siddiqa (may Allah be pleased with her) narrates: When the private part meets the private part, then ghusl becomes obligatory. When I and the Prophet Muhammad (peace be upon him) did this, we would perform ghusl.
