It was narrated from Abu Hurairah that the Messenger of Allah said: “Whoever performs Hajj to this House, and does not have sexual relations nor commit any disobedience, will go back like the day his mother bore him.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ مِسْعَرٍ، وَسُفْيَانَ، عَنْ مَنْصُورٍ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ حَجَّ هَذَا الْبَيْتَ فَلَمْ يَرْفُثْ وَلَمْ يَفْسُقْ رَجَعَ كَمَا وَلَدَتْهُ أُمُّهُ " .
