O Allāh, send prayers upon Muhammad and the followers of Muhammad, just as You sent prayers upon Ibrāhīm and upon the followers of Ibrāhīm. Verily, You are full of praise and majesty. O Allāh, send blessings upon Muhammad and upon the family of Muḥammad, just as You sent blessings upon Ibrāhīm and upon the family of Ibrāhīm. Verily, You are full of praise and majesty.
