Chapter: At the beginning of Islam, intercourse did not necessitate ghusl unless semen was emitted, then that was abrogated and ghusl becomes obligatory for intercourse
Sa'id al-Khudri narrated it from his father: I went to Quba' with the Messenger of Allah (ﷺ) on Monday till we reached (the habitation) of Banu Salim. The Messenger of Allah (ﷺ) stood at the door of 'Itban and called him loudly. So he came out dragging his lower garnment. Upon this the Messenger of Allah (ﷺ) said: We have made this man to make haste 'Itban said: Messenger of Allah, if a man parts with his wife suddenly without seminal emission, what is he required to do (with regard to bath)? The Messenger of Allah (ﷺ) said: It is with the seminal emission that bath becomes obligatory.
Abu al. 'Ala' bin al-Shikhkhir said: The Messenger of Allah (ﷺ) abrogated some of his commands by others, just as the Qur'an abrogates some part with the other.
Abu Sa'id al-Khudri reported: The Messenger of Allah (ﷺ) happened to pass by (the house) of a man amongst the Ansar, and he sent for him. He came out and water was trickling down from his head. Upon this he (the Holy Prophet) said: Perhaps we put you to haste. He said: Yes Messenger of Allah. He (the Holy Prophet) said: When you made haste or semen is not emitted, bathing is not obligatory for you, but ablution is binding. Ibn Bashshir has narrated it with a minor alteration.
Ubayy Ibn Ka'b reported: I asked the Messenger of Allah (ﷺ) about a man who has sexual intercourse with his wife, but leaves her before orgasm. Upon this he (the Holy Prophet) said: He should wash the secretion of his wife, and then perform ablution and offer prayer.
Ubayy ibn Ka'b narrated it from the Messenger of Allah (ﷺ) that he said: If a person has sexual intercourse with his wife, but does not experience orgasm, he should wash his organ and perform an ablution.
Zaid bin Khalid al-Jubani reported that he askad 'Uthman bin 'Affan: What is your opinion about the man who has sexual intercourse with his wife, but does not experience orgasm? 'Uthman said: He should perform ablution as he does for prayer, and wash his organ. 'Uthmin also said: I have heard it from the Messenger of Allah (ﷺ) .
