Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ رُوِيَ: «أَنَّ مَنْ نَظَرَ إِلَى اَلْكَعْبَةِ لَمْ يَزَلْ تُكْتَبُ لَهُ حَسَنَةٌ وَ تُمْحَى عَنْهُ سَيِّئَةٌ حَتَّى يَصْرِفَ بِبَصَرِهِ عَنْهَا ».
It has been narrated: "Whoever looks at the Kaaba continuously will have a good deed written for them and a sin erased from them until they turn their gaze away from it."
