"A friend cannot be considered a friend unless he is tested on three occasions: in time of need, behind your back and after your death." -Ali ibn abi Talib (raa)
All humans are dead except those who have knowledge ... and all those who have knowledge are asleep except for those who do good deeds... and those who do good deeds are deceived except those who are sincere... and those who are sincere are always in a state of worry.
