Saad bin Abu Waqqas was among his camels when his son Umar came to him. When Saad saw him, he said, "I seek refuge in Allah from the evil of this rider."Umar dismounted and said to him, "Have you settled down with your camels and sheep, leaving the people to dispute over rulership among themselves?"Saad struck him on the chest and said, "Be quiet. I heard the Messenger of Allah ﷺ say, 'Allah loves the servant who is godfearing, self-sufficient, and unnoticed.'"
كان سعد بن أبي وقاص في إبله، فجاءه ابنه عمر، فلما رآه سعد قال: أعوذ بالله من شر هذا الراكب، فنزل، فقال له: أنزلت في إبلك وغنمك وتركت الناس يتنازعون الملك بينهم؟ فضرب سعد في صدره، فقال: اسكت سمعت رسول الله ﷺ يقول: إن الله يحب العبد التقي الغني الخفي.
Muslim narrated it in his chapter on asceticism (2965) through several routes from Abu Bakr Hanafi, who said, Bukayr bin Mismar narrated to us, who said, Amir bin Saad narrated to me, and he mentioned it.Hafiz said in al-Isabah (3208), "When Uthman was killed, he withdrew from the strife and stayed in his house."
