Around prayer
After completing wudu
أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ
Transliteration
Ashhadu an la ilaha illa-llahu wahdahu la sharika lahu, wa ashhadu anna Muhammadan abduhu wa rasuluh.
Translation
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.
Context
Whoever says it after wudu, the eight gates of Paradise are opened for him to enter from whichever he wishes (Muslim 234).
