Sahih al-Bukhari, Hadith 6005 ⓘ
Narrated Sahl bin Sa`d: The Prophet said, "I and the person who looks after an orphan and provides for him, will be in Paradise like this," putting his index and middle fingers together.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْوَهَّابِ، قَالَ حَدَّثَنِي عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، قَالَ حَدَّثَنِي أَبِي قَالَ، سَمِعْتُ سَهْلَ بْنَ سَعْدٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَنَا وَكَافِلُ الْيَتِيمِ، فِي الْجَنَّةِ هَكَذَا " . وَقَالَ بِإِصْبَعَيْهِ السَّبَّابَةِ وَالْوُسْطَى.
