The Book of Purification
Taking Ghusl (bath) And the precepts regarding Sexual Impurity
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِذَا جَلَسَ بَيْنَ شُعَبِهَا اَلْأَرْبَعِ, ثُمَّ جَهَدَهَا, فَقَدْ وَجَبَ اَلْغُسْلُ } مُتَّفَقٌ عَلَيْه ِ [1] .
Narrated Abu Huraira (rad): Allah’s Messenger (ﷺ) said that, “If one of you sits between her legs (of a woman) and penetrates her, Ghusl (bath) is obligatory.” [Agreed upon].
