"Rabbana Taqabbal Minna Innaka Anta Sami'ul Alim" is a powerful and frequently recited supplication in Islam. It translates to "Our Lord, accept (this) from us. Indeed, You are the All-Hearing, the All-Knowing." This dua is often recited after acts of worship, such as prayer or fasting, seeking Allah's acceptance and acknowledging His omniscience.
