Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:He who came to this House (Ka'ba) (with the intention of performing Pilgrimage), and neither spoke indecently nor did he act wickedly. would return (free from sin) as on the (very first day) his mother bore him.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَزُهَيْرُ بْنُ حَرْبٍ، قَالَ يَحْيَى أَخْبَرَنَا وَقَالَ، زُهَيْرٌ حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أَتَى هَذَا الْبَيْتَ فَلَمْ يَرْفُثْ وَلَمْ يَفْسُقْ رَجَعَ كَمَا وَلَدَتْهُ أُمُّهُ " .
