Salim bin Abdullah narrates from his father: When the Prophet Muhammad (peace be upon him) was returning from Hajj or Umrah or perhaps from a battle, and he reached a high and rugged place, he (peace be upon him) recited: "There is no deity except Allah, He is the One and Only, He has no partner, sovereignty belongs to Him alone. All praise is due to Him alone and He has power over everything. If Allah wills, we are those who turn back, those who repent, those who worship, those who praise our Lord. Allah has fulfilled His promise, helped His servant, and He alone defeated the armies (of the enemy)."
