2.  Imam  Muhammad  Baqir  (a.s.)  narrates  that  the  Holy Prophet  (s.a.w.s.)  said,  “One  who  is  wary  of  his  hard- heartedness and if he strokes the head of an orphan gently, he will become soft-hearted by the order of Allah and it is the  right of an orphan.” It is  narrated in another  tradition that  one  should  make  orphans  sit  in  ones  gatherings  and stroke  their  heads  gently  so  that  one  can  become  soft- hearted. One becomes soft-hearted by the order of Allah as soon as he/she performs this deed.”
