"Whoever supports an orphan from among his own or any other family; he will be as close to me in Heaven as these fingers are close to each other."
Rasulullah (PBUH) made a motion of his index and middle fingers (while he said this) and there was only a little space between the two. Allah has guided in the Quran at several places of how to treat orphans. If someone treats an orphan in a bad manner he would not be permitted to enter heaven.
This does not mean that you only have the responsibility of treating the orphan from your relatives’ but also the orphans with whom they have no particular blood tie with. Thus it is the responsibility of the whole society to treat each and every Muslim to treat the orphans with care and affection.
