If you do not aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [ of Makkah ] as one of two , when they were in the cave and he said to his companion , " Do not grieve ; indeed Allah is with us . " And Allah sent down his tranquillity upon him and supported him with angels you did not see and made the word of those who disbelieved the lowest , while the word of Allah - that is the highest .
