taharah- issues of Wu'du

Reciting dua after doing wu’du after doing wu’du is Masnoon [Muslim, Tirmizi]

أَشْهَدُ أَنْ لَا إِلَهَ إلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ، وَأَشْهَدُ أَنَّ مُحَمَّداً عَبْدُهُ وَرَسُولُهُ

"Ash-hadu "an la "ilaha "illallahu wahdahu la sharika lahu wa "ash-hadu "anna
Muhammadan 'abduhu wa Rasuluhu.

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. Muslim 1/209

اللَّهُمَّ اجْعَلْنِي مِنَ التَّوَّابِينَ وَاجْعَلْنِي مِنَ الْمُتَطَهِّرِينَ

Allahummaj 'alni minat-tawwabina waj'alni minal-mutatahhirin.

 O Allah, make me among those who turn to You in repentance, and make me among those who are purified. Nasa'i

 سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ، أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا أَنْتَ، أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ

Subhanaka Allahumma wa bihamdika, "ash-hadu "an la "ilaha "illa "Anta, 'astaghfiruka wa 'atubu 'ilayk.

 Glory is to You, O Allah, and praise; I bear witness that there is none worthy of worship but You. I seek Your forgiveness and turn to You in repentance. Nasa'i
