Do not drive away those (poor people like Bilal, Ammar and Suhaib) who call on their Lord morning and evening, seeking only to gain His favor. You are in no way accountable for their deeds nor they are in any way accountable for yours. So if you drive them away you shall be counted among the wrongdoers.
Meaning:-
Wrongdoer: a person who behaves illegally or dishonestly; an offender.
