2ـ وَبِهَذَا الإِسْنَادِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ إِنَّ لله تَبَارَكَ وَتَعَالَى حَوْلَ الْكَعْبَةِ عِشْرِينَ وَمِائَةَ رَحْمَةٍ مِنْهَا سِتُّونَ لِلطَّائِفِينَ وَأَرْبَعُونَ لِلْمُصَلِّينَ وَعِشْرُونَ لِلنَّاظِرِينَ.

2. It is narrated from him (narrator of previous Hadith) from ibn abu ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that Allah, the most Blessed, the most High, has one hundred twenty blessings around al-Ka’bah of which sixty are for those who perform Tawaf, forty for those who perform salat (prayer) and twenty for those who look at al-Ka’bah.’”
