From the morals and the manners of the Salaf was that they would not be proud of their own actions but they would see deficiency in them.
Mutarrif Ibn Abdullah (rahimahullah) said, “It is more beloved to me to spend the night sleeping and wake up regretful than to spend the night standing in prayer and wake up proud of myself.”
Hasan Al Basri (rahimahullah) used to say, “If the all the actions of the son of Aadam were good he would have destroyed himself through pride, but Allaah tries him by showing him his shortcomings.”
If the Salaf were praised they would say, ” O Allaah make me better than what they say and forgive me for what they do not know.”
Umar (radiyallahu anhu) would say, “O Allaah I seek your protection from the bad that they say and I seek your forgiveness for what they do not know.”
Bishr Al Hafy (rahimahullah) would say, “If you see a person who is vain about his knowledge and proud about himself, then know that he has completed his failure.”
Abdul Aziz Ibn Abi Rawad (rahimahullah) would say, “If we remember the condition of the Salaf between ourselves then all of us will be exposed.”
