Abu Nuwas was a person who loved to drink and say obscene things, such that he would even make up verses of poetry and sing about inappropriate things. However, he underwent a change and repented to God. People were surprised—Abu Nuwas, who was a known drunkard? Abu Nuwas the lewd man? In a sense, it was almost as though they believed Allah would not forgive him and that Allah would not have mercy on him. So he wrote verses of poetry, and they found these verses under the bed that he died upon. The lines in the poem said:
O my Lord, if the greatness of my sins increase, then I know that Your forgiveness is greater
If only the righteous called on You, then who would the criminal go to?
I call on You my Lord, as you commanded, with reverence
And if You turn my hands away, then who else will have mercy?
