It is narrated from Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with them both) concerning the saying of Allah, Mighty and Majestic: "And do not throw yourselves with your own hands into destruction", that he said: "A man would commit a sin and say: 'I will not be forgiven.' So Allah, Mighty and Majestic, revealed this verse: 'And do not throw yourselves with your own hands into destruction, and do good; indeed, Allah loves those who do good.'"
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith was narrated from Simak bin Harb only by Hammad bin Salamah."
