Wudu is the daily key to prayer — but it is also a quiet act of forgiveness. The Prophet ﷺ taught that with every drop of water that falls from a believer's limbs, sins fall with it. And he ﷺ taught a short dua to recite at the end of wudu, with one of the most extraordinary promises in all of hadith literature.
The dua after completing wudu
أَشْهَدُ أَنْ لَا إِلَٰهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ
Ash-hadu an la ilaha illa Allah, wahdahu la sharika lah, wa ash-hadu anna Muhammadan 'abduhu wa rasuluh.
I bear witness that there is no god but Allah, alone, with no partner, and I bear witness that Muhammad is His servant and messenger.
(Sahih Muslim 234 — narrated by Umar ibn al-Khattab (RA))
The promise attached to it
Whoever performs wudu and does it well, then says: 'I bear witness that there is no god but Allah alone, with no partner, and I bear witness that Muhammad is His servant and messenger' — the eight gates of Paradise will be opened for him; he may enter through whichever he wishes.
An additional Sunnah recommended by at-Tirmidhi
اللَّهُمَّ اجْعَلْنِي مِنَ التَّوَّابِينَ، وَاجْعَلْنِي مِنَ الْمُتَطَهِّرِينَ
Allahumma-j'alni minat-tawwabin, waj'alni minal-mutatahhirin.
O Allah, make me from those who constantly turn back to You in repentance, and make me from those who keep themselves pure.
(Jami at-Tirmidhi 55)
Why these words?
Wudu is the threshold of prayer, and prayer is the believer's daily standing before Allah. Renewing the testimony of faith (the Shahadah) at the moment our body is at its purest is a quiet way of saying: I cleansed my body, now let me also cleanse and reaffirm my heart.
How to use the dua
- Complete wudu carefully — wash each limb three times where the Sunnah recommends.
- Look up to the sky after the last drop, raise your gaze with humility, and recite the Shahadah dua.
- Add the Tirmidhi version if you can — it adds repentance and purity to faith and witnessing.
Hadith reference
The main dua is from Sahih Muslim (234), narrated by Umar ibn al-Khattab (RA). The additional words are reported in Jami at-Tirmidhi (55). Together they form the most complete post-wudu adhkar taught by the Prophet ﷺ.
