WARNING AGAINST NOT HATING SINS
Malik ibn Dinar (rahmatullahi alayh) says: Allah asked his angels to destroy a certain town. The angels said that there lived in that town a devoted servant of His busy praying to Him. Came the command: Let him too taste the punishment because he never showed his anger against people dis¬obeying Us and committing sins openly, not even with a sign of it on his face.
To Sayyidna Yusha` ibn Nun (علیہ السلام) ، (Joshua) the Israelite prophet, Allah Almighty revealed that one hundred thousand of his people will be destroyed by a punishment. Of them, forty thousand were righteous and sixty thousand, evil. Sayyidna Yusha` (علیہ السلام) said: 0 Lord, the ruin of the evil is obvious but why the good ones? It was said: The good ones had friendly relations with the bad ones. Together, they ate and drank and enjoyed life and never frowned on people sinning and disobeying their Creator.
