When starting ablution
Bismillah In the name of Allah
Upon completing the ablution
I bear witness that none has the right to be worshipped except Allah, alone without partner and I bear witness that Muhammad is His slave and messenger.
O Allah make me of those who return to You often in repentance and make me of those who remain clean and pure.
How perfect You are Allah, and I praise You. I bear witness that none has the right to be worshipped except You, I seek Your forgiveness and turn in repentance to You.
