Al-Adab Al-Mufrad 126
Jabir said, "A man came to the Prophet ﷺ to complain to him about the enmity of his neighbour. While he was sitting between the Corner and the Maqam, the Prophet ﷺ approached with a man who was wearing a white garment. They went to the Maqam where they were praying for the dead. He went up to the Prophet ﷺ and said, 'May my mother and my father be your ransom, Messenger of Allah! Who is this man I see with you wearing the white garment?' 'You saw him?' he asked. 'Yes,' the man replied. He said, 'Then you have seen much good. That was Jibril ﷺ the Messenger of my Lord. He kept on recommending that I treat my neighbours well until I thought that he would order me to make them my heirs.'"
حَدَّثَنَا مَخْلَدُ بْنُ مَالِكٍ، قَالَ: حَدَّثَنَا أَبُو زُهَيْرٍ عَبْدُ الرَّحْمَنِ بْنُ مَغْرَاءَ، قَالَ: حَدَّثَنَا الْفَضْلُ يَعْنِي ابْنَ مُبَشِّرٍ قَالَ: سَمِعْتُ جَابِرًا يَقُولُ: جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ يَسْتَعْدِيهِ عَلَى جَارِهِ، فَبَيْنَا هُوَ قَاعِدٌ بَيْنَ الرُّكْنِ وَالْمَقَامِ إِذْ أَقْبَلَ النَّبِيُّ ﷺ وَرَآهُ الرَّجُلُ وَهُوَ مُقَاوِمٌ رَجُلاً عَلَيْهِ ثِيَابٌ بَيَاضٌ عِنْدَ الْمَقَامِ حَيْثُ يُصَلُّونَ عَلَى الْجَنَائِزِ، فَأَقْبَلَ النَّبِيُّ ﷺ فَقَالَ: بِأَبِي أَنْتَ وَأُمِّي يَا رَسُولَ اللهِ، مَنِ الرَّجُلُ الَّذِي رَأَيْتُ مَعَكَ مُقَاوِمَكَ عَلَيْهِ ثِيَابٌ بِيضٌ؟ قَالَ: أَقَدْ رَأَيْتَهُ؟ قَالَ: نَعَمْ، قَالَ: رَأَيْتَ خَيْرًا كَثِيرًا، ذَاكَ جِبْرِيلُ ﷺ رَسُولُ رَبِّي، مَا زَالَ يُوصِينِي بِالْجَارِ حَتَّى ظَنَنْتُ أَنَّهُ جَاعِلٌ لَهُ مِيرَاثًا.
