Hadith #3

3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ أَبِي عَبْدِ الله الْخَزَّازِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ إِنَّ لِلْكَعْبَةِ لَلَحْظَةً فِي كُلِّ يَوْمٍ يُغْفَرُ لِمَنْ طَافَ بِهَا أَوْ حَنَّ قَلْبُهُ إِلَيْهَا أَوْ حَبَسَهُ عَنْهَا عُذْرٌ.

3. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from abu ‘Abd Allah al-Khazzaz who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that for al-Ka’bah, there is a moment every day in which forgiveness is granted to those who perform Tawaf around it, or whose hearts incline toward it or are prevented from visiting it for a good reason.”
