Sahih Muslim , Book 32, Hadith 6356 (USC-MSA) ⓘ
Ibn Umar reported Allah's Messenger as saying: Gabriel impressed upon me (the kind treatment) towards the neighbour (so much) that I thought as if he would soon confer upon him the (right) of inheritance.
حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ عُمَرَ الْقَوَارِيرِيُّ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ عُمَرَ بْنِ مُحَمَّدٍ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ ابْنَ عُمَرَ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَا زَالَ جِبْرِيلُ يُوصِينِي بِالْجَارِ حَتَّى ظَنَنْتُ أَنَّهُ سَيُوَرِّثُهُ " .
