Sayyidina Sad ibn Waqqas (RA) narrated that Allah’s Messenger (SAW) said, If anyone who hears the muadhdhin call the adhan says: “And I bear witness that there is no God but Allah, the One. He has no partner. And that Muhmmad is His slave and His Messenger. I am pleased with Allah as Lord, and with Islam as religion and with Muhmmad as a Messenger”. then Allah will forgive his sins.
