Abu Huraira reported that Allah's Messenger (ﷺ) said:
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ ، حَدَّثَنَا إِسْحَاقُ بْنُ عِيسَى ، حَدَّثَنَا مَالِكٌ ، عَنْ ثَوْرِ بْنِ زَيْدٍ، الدِّيلِيِّ قَالَ سَمِعْتُ أَبَا الْغَيْثِ ، يُحَدِّثُ عَنْ أَبِي هُرَيْرَةَ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " كَافِلُ الْيَتِيمِ لَهُ أَوْ لِغَيْرِهِ أَنَا وَهُوَ كَهَاتَيْنِ فِي الْجَنَّةِ " . وَأَشَارَ مَالِكٌ بِالسَّبَّابَةِ وَالْوُسْطَى .
One who looks after the orphan whether he is his relative or not, I and he would be together in Paradise like this, and Malik (explained it) with the gesture by drawing his index finger and middle finger close together.
