The Messenger of Allāh (May Allāh praise him and Peace be upon him) said, “Whenever any of you performs his wuḍū` (ablution) well then says “I testify that there is none worthy of worship other than Allāh, alone with no partners, and I testify that Muḥammad is His Slave and Messenger”, the eight doors of Paradise are opened for him and he will enter via whichever of them he wishes.” [Reported by Al Imām Muslim]
