6ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عَلِيِّ بْنِ عَبْدِ الْعَزِيزِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ مَنْ نَظَرَ إِلَى الْكَعْبَةِ بِمَعْرِفَةٍ فَعَرَفَ مِنْ حَقِّنَا وَحُرْمَتِنَا مِثْلَ الَّذِي عَرَفَ مِنْ حَقِّهَا وَحُرْمَتِهَا غَفَرَ الله لَهُ ذُنُوبَهُ وَكَفَاهُ هَمَّ الدُّنْيَا وَالآخِرَةِ.

6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn abu ‘Umayr from Ali ibn ‘Abd al-‘Aziz who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that Allah forgives one’s sins and suffices him in this world and in the next life, if he looks at al-Ka‘bah with proper understanding and then recognizes our rights and sanctity just as his recognition of the rights and sanctity of al-Ka‘bah.” (The following Chapter is best explained in the form of fatwa).
