question #1 Sahih Muslim 348a, Book 3, Hadith 105 : What are the conditions that make bathing obligatory after sexual intercourse in Islam?

The Apostle of Allah (ﷺ) said: When a man has sexual intercourse, bathing becomes obligatory (both for the male and the female). In the hadith of Matar the words are: Even if there is no orgasm. Zuhair has narrated it with a minor alteration of words.
