From Abu Dzar RA, he said, “O Messenger of Allah, what do you think if I am weak (unable) to perform some deeds?” The Prophet SAW said:
تَكُفُّ شَرَّكَ عَنِ النَّاسِ فَإِنَّهَا صَدَقَةٌ مِنْكَ عَلَى نَفْسِكَ
“Refrain from harming people, for this is a charity from you to yourself.”
Sahih Muslim (84)
