(O ye who believe!) i.e. Muhammad and his Companions (Remember Allah's favour unto you) recollect Allah's grace by driving away from you the harm of the enemy, (how a people) the people of the Banu Qurayzah (were minded to stretch out their hands against you) to kill you (but He withheld) He prevented (their hands from you) from killing you; (and keep your duty to Allah) fear Allah in relation to that which He has commanded you. (In Allah let believers put their trust) the believers should rely on Allah.
