What is tahiyatul wudhu?

Tahiyatul Wudhu, also known as the "salutation of ablution," refers to a Sunnah prayer performed after completing the ritual of Wudhu (ablution) in Islamic practice. This two-unit prayer is a way to thank Allah for the ability to perform Wudhu and seek forgiveness. While it is not obligatory, it is highly recommended as a means of earning additional rewards and enhancing one's spiritual state before engaging in further prayers.
