Sa'd bin Abu Waqqas (May Allah be pleased with him) reported: The Prophet (ﷺ) said, "He who says after the Adhan: 'Ash-hadu an la ilaha illallah Wah-dahu la sharika Lahu; wa ash-hadu anna Muhammadan 'abduhu wa Rasuluhu, radhitu Billahi Rabban, wa bi Muhammadin Rasulan, wa bil Islami Dinan ,' his sins will be forgiven." .
