If you find that somebody is not grateful for all that you have done for him, then do not get disappointed because often you will find that someone else feels under your obligation though you have done nothing for him and thus your good deeds will be compensated, and Allah will reward you for your goodness.
Ali ibn Abi TalibA friend cannot be considered a friend until he is tested in three occasions: in timeof need, behind your back, and after your death.
