أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ
Ash-hadu an lā ilāha illallāhu waḥdahu lā sharīka lah, wa ash-hadu anna Muḥammadan ʿabduhu wa rasūluh
I bear witness that none has the right to be worshipped but Allah alone, and that Muhammad is His servant and Messenger. (After wudu — the eight gates of Paradise open for him.)
