Imam Sadiq (a.s) told Mufaz'zil ibn Amr: “O' Mufaz'zil! Abstain from committing sins, and admonish our followers to abstain from sins. I swear by God that there is nothing you face more than sins. I swear by God that whenever one of you gets ill, it is due to the sins that he has committed. Also if any one of you are is deprived of his daily bread and wonders why, it is because of the sins that he has committed. And if he gets oppressed by a king and wonders why it is due to the sins he has committed. I swear by God that you will not be questioned about these sins in the Hereafter.”
