It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Noble Prophet (peace and blessings be upon him) would return from Hajj, Jihad, or Umrah, he would recite this supplication upon ascending any elevated ground: "Allah is the Greatest, Allah is the Greatest, there is no deity except Allah, He is alone, He has no partner, His is the dominion and His is the praise, and He is powerful over all things. We are returning in repentance, in prostration, in worship, and returning while praising our Lord. Allah has fulfilled His promise, helped His servant, and defeated all the armies alone."
