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  

[Machine] The Messenger of Allah ﷺ said, "Me and the caretaker of an orphan will be like these two in Paradise." And he pointed with his index and middle fingers, separating them slightly.  

قَالَ رَسُولُ اللهِ ﷺ أَنَا وَكَافِلُ الْيَتِيمِ كَهَاتَيْنِ فِي الْجَنَّةِ وَأَشَارَ بِالسَّبَّابَةِ وَالْوُسْطَى وَفَرَّقَ بَيْنَهُمَا قَلِيلًا  

the Messenger of Allah said: " I and the sponsor of an orphan shall be in Paradise like these two."And he indicaed with his fingers, meaning his index and his middle finger (Using translation from Tirmidhī 1918)   

قَالَ رَسُولُ اللَّهِ ﷺ «أَنَا وَكَافِلُ الْيَتِيمِ فِي الْجَنَّةِ هَكَذَا وَأَشَارَ بِالسَّبَّابَةِ وَالْوُسْطَى»  

[Machine] "The Prophet ﷺ said, 'The one who takes care of an orphan, whether he is his own child or someone else's, and I will be together like these two (fingers) in Paradise." It means, the rosary and the middle finger.  

أَنَّ النَّبِيَّ ﷺ قَالَ «كَافِلُ الْيَتِيمِ لَهُ أَوْ لِغَيْرِهِ إِذَا اتَّقَى مَعِي فِي الْجَنَّةِ كَهَاتَيْنِ» يَعْنِي الْمُسَبِّحَةَ وَالْوُسْطَى  

"كَافِلُ اليَتِيم لَهُ وَلِغَيرِهِ- أنَا وَهُوَ كهَاتَينِ في الْجَنَّة".  

"أنَا وَكَافلُ اليَتيم لَهُ أَوْ لغَيْرِه إِذَا اتَّقَى اللَّهَ فِى الجَنَّة كهَاتَيْنِ، وَأَشَار بإِصْبَعِهِ المُسَبِّحَة والوُسْطَى".  

"أنَا وَكَافِلُ الْيَتِيم فِى الجَنَّة كَهَذَا وَأشَارَ بالسَّبَّابَة وَالوُسْطَى".
