O our people, respond to the Caller [i.e., Messenger] of Allāh1 and believe in him; He [i.e., Allāh] will forgive for you your sins and protect you from a painful punishment.
O our people, respond to the truth that Muhammad calls you towards and believe that he is a messenger from his Lord, and Allah will forgive your sins and save you from a painful punishment that awaits you if you do not respond to the truth that he calls you towards and do not believe that he is a messenger from his Lord.
