It is reported from Imâm Sufyân b. ‘Uyainah – Allâh have mercy on him – that he said:

Whoever’s sin was because of [carnal] desires, hope for him (as he may repent and be forgiven); but whoever’s sin was out of pride, fear for him. For indeed, Âdam sinned out of simple desire, and was forgiven; whereas Iblîs sinned out of pride, and was cursed.
