باب فِيمَنْ يَوَدُّ رُؤْيَةَ النَّبِيِّ صلى الله عليه وسلم بِأَهْلِهِ وَمَالِهِ ‏‏
Sahih Muslim 2832

Abu Huraira reported Allah's Messenger (ﷺ) as saying:

The people most loved by me from amongst my Ummah would be those who would come after me but everyone amongst them would have the keenest desire to catch a glimpse of me even at the cost of his family and wealth.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مِنْ أَشَدِّ أُمَّتِي لِي حُبًّا نَاسٌ يَكُونُونَ بَعْدِي يَوَدُّ أَحَدُهُمْ لَوْ رَآنِي بِأَهْلِهِ وَمَالِهِ ‏"‏ ‏.‏
