Had there not been five bad qualities, all the people would have been righteous. Contentment with ignorance; love for worldly life; miserliness inspite of much wealth; ostentation in (good) deeds; and pride in their own intelligence.
Ali ibn Abi TalibIf 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 Talib
