Sahih al-Bukhari 1819Book 27, Hadith 14
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنْ مَنْصُورٍ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ حَجَّ هَذَا الْبَيْتَ، فَلَمْ يَرْفُثْ وَلَمْ يَفْسُقْ، رَجَعَ كَمَا وَلَدَتْهُ أُمُّهُ ".
Allah's Messenger (ﷺ) said, "Whoever performs Hajj to this House (Ka`ba) and does not approach his wife for sexual relations nor commits sins (while performing Hajj), he will come out as sinless as a newlyborn child. (Just delivered by his mother).
