DU'A AFTER PERFORMING WUDU (ABLUTION)
أَشْهَدُ أَنْ لَا إِلَـهَ إِلاَّ اللّهُ وَحْدَهُ لَا شَريـكَ لَـهُ وَأَشْهَدُ أَنَّ مُحَمَّـداً عَبْـدُهُ وَرَسُـولُـهُ'
ashhadu alla 'iilah 'iila alllh wahdah la sharika lah wa'ashhad 'ann muhammadaan abduh warasuwluh
I bear witness that there is no god but Allah alone, He has no partner, and I bear witness that Muhammad is His servant and His Messenger.
(Muslim)
اَللَّهُـمَّ اجْعَلْنِـي مِنَ التَّـوَّابِينَ وَاجْعَـلْنِي مِنَ الْمُتَطَهِّـرِينَ
aalllahumm ajealniy min alttـwwabin wajealni min almutatahhirin
O Allah, make me among those who repent and make me among those who purify themselves.
(At-tirmidhi)
سُبْحـَانَكَ اللَّهُـمَّ وَبِحَمْدِكَ، أَشْهَـدُ أَنْ لاَ إِلَهَ إِلاَّ أَنْتَ، أَسْتَغْفِرُكَ وَأَتُوبُ إِلَـيْكَ
subhanak alllahumm wabihamdika, 'ashhad 'an la 'iilah 'iila 'anta, 'astaghfiruk wa'atub 'iilayk
Glory be to God, and with your praise, I bear witness that there is no god but You, I seek Your forgiveness and repent to You.
