Upon completing the ablution #1

أَشْهَدُ أَنْ لَا إِلٰهَ إِلَّا اللّٰهُ وَحْدَهُ لَا شَرِيْكَ لَهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُوْلُهُ

I bear witness that none has the right to be worshipped but Allah alone, Who has no partner; and I bear witness that Muhammad is His slave and His Messenger.

Ash-hadu 'an laa 'ilaaha 'illallaahu wahdahu laa shareeka lahu wa 'ash-hadu 'anna Muhammadan 'abduhu wa Rasooluhu.
