Dua is defined as any invocation or prayer addressed to Allah. It is the essence of ibadah or worship. Dua should be the first and the last resort of the believer, as it is at its core a conversation with Allah. Perspectives on the ideal timing, presentation, and phrasing of dua can vary widely among the faithful, but there is universal agreement that you must approach dua with humility, clarity, submission, and certainty that Allah will respond.
