Al-Adab Al-Mufrad, Book 17, Hadith 350 (English) ⓘ
Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "A man visited a brother of his in a village, so Allah put an angel in wait for him on the road. He asked, 'Where are you going?' He replied, 'To a brother of mine in this village.' He said, 'Is he responsible for some blessing you have?' He said, 'No, I love him for Allah.' He said, 'I am a messenger of Allah to you. Allah loves you as you love him.'"
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، وَمُوسَى بْنُ إِسْمَاعِيلَ، قَالاَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: زَارَ رَجُلٌ أَخًا لَهُ فِي قَرْيَةٍ، فَأَرْصَدَ اللَّهُ لَهُ مَلَكًا عَلَى مَدْرَجَتِهِ، فَقَالَ: أَيْنَ تُرِيدُ؟ قَالَ: أَخًا لِي فِي هَذِهِ الْقَرْيَةِ، فَقَالَ: هَلْ لَهُ عَلَيْكَ مِنْ نِعْمَةٍ تَرُبُّهَا؟ قَالَ: لاَ، إِنِّي أُحِبُّهُ فِي اللهِ، قَالَ: فَإِنِّي رَسُولُ اللهِ إِلَيْكَ، أَنَّ اللَّهَ أَحَبَّكَ كَمَا أَحْبَبْتَهُ.
