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. (Using translation from Muslim 2983)
قَالَ رَسُولُ اللهِ ﷺ كَافِلُ الْيَتِيمِ لَهُ أَوْ لِغَيْرِهِ أَنَا وَهُوَ كَهَاتَيْنِ فِي الْجَنَّةِ إِذَا اتَّقَى اللهَ وَأَشَارَ مَالِكٌ بِالسَّبَّابَةِ وَالْوُسْطَى
