6. Abu Ali al-Ash’ari has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from Husayn ibn Yazid from Abu ‘Abdillah (a.s.) who has said the following: “The Messenger of Allah has said, ‘Plea for forgiveness, and the words: ‘No one deserves to be worshipped except Allah’ are the best forms of worship.’ Allah, the Most Majestic, the Most Mighty, has said, ‘Notice that Allah is the only Lord who deserves to be worshipped. Ask forgiveness for your sins. . . .’” (47:19)
