Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ قَالَ عَلَيْهِ اَلسَّلاَمُ: «دُخُولُ اَلْكَعْبَةِ دُخُولٌ فِي رَحْمَةِ اَللَّهِ وَ اَلْخُرُوجُ مِنْهَا خُرُوجٌ مِنَ اَلذُّنُوبِ مَعْصُومٌ فِيمَا بَقِيَ مِنْ عُمُرِهِ مَغْفُورٌ لَهُ مَا سَلَفَ مِنْ ذُنُوبِهِ.
Imam عليه السلام said: "Entering the Kaaba is an entry into the mercy of Allah سبحانه وتعالى, and exiting it is an exit from sins, making one protected for the remainder of their life, with forgiveness granted for all past sins."
