Hazrat Habib bin Abi Thabit says: The eyebrows of Hazrat Yaqub (peace be upon him) had drooped over his eyes. He used to lift them with a piece of cloth. Once, he was asked: How did this condition happen to you? He replied: Due to old age and the abundance of sorrows. Upon this, Allah the Blessed and Exalted revealed to him: O Yaqub (peace be upon him), have you complained about Me? Hazrat Yaqub (peace be upon him) said: O my Lord! This is a great mistake that has occurred from me. So please forgive me.
