Dua Masura English Translation
O Allah, forgive me what I have sent before me and what I have left behind me, what I have concealed and what I have done openly, what I have done in excess, and what You are better aware of than I. You are the One Who sends forth and You are the One Who delays. There is none worthy of worship but You.
After tashahood, The Messenger of Allah (ﷺ) supplicate this dua at the end, before saying salaam.
