Al-Kāfi - The Book of Haj

َّدُ بْنُ يَحْيَى عَنْ ٠َدَ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ الْقَدَّاحِ عَنْ جَعْفَرٍ عَنْ أَبِيهِ (عَلَيْهِ٠) قَالَ سَأَلْتُهُ عَنْ دُخُولِ الْكَعْبَةِ قَالَ الدُّخُولُ فِيهَا دُخُولٌ فِي رَحْ٠َةِ الله وَالْخُرُوجُ ٠2.

Muhammad ibn Yahya has narrated from Muhammad ibn Ahmad from Ya’qub ibn Yazid from ibn Faddal from ibn al-Qaddah who has said the following: “Ja’far (a.s.), has said, ‘I asked my father (a.s.), about entering al-Ka‘bah. He said, ‘Entering al-Ka‘bah is entering in the mercy of Allah.

Coming out of al-Ka‘bah is coming out of sins, and protection in the rest of one’s life and his past sins forgiven.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (18/225))
