1. Imam Ja’far Sadiq (a.s.) narrates that the Almighty Allah told Prophet Musa (a.s.), “O Musa! This world is a house of punishment. When Adam committed a Tark-e-Awla (leaving a recommended deed), he was sent to this world in return. Whenever a person commits mistake, he is punished in this world. This world is cursed along with all the things present in it except for what is done for Me, the Lord. O Musa, My virtuous servants keep away from this world as much knowledge as they have. And others who are ignorant of Me, chase this world. The eyes of none of My creatures who consider this world great could get peace, while those who considered this world unworthy could get heaps of benefits.”
