وَعَدَ اللَّهُ الْمُؤْمِنِينَ وَالْمُؤْمِنَاتِ جَنَّاتٍ
Allah has promised believing men and women gardens. (Al-Tawbah 9:72)
An objection points out that other promises mention righteous action together with faith. The reply distinguishes the essential importance of righteous acts from the claim that every major sin cancels faith itself.
A sinful believer may lack required righteous conduct and deserve punishment without automatically ceasing to be a believer. Other evidence is brought to explain why the reward associated with faith is not wholly erased.
