33.23. Among the believers are men (of highest valor) who have been true to their covenant with God: among them are those who have fulfilled their vow (by remaining steadfast until death), and those who are awaiting (its fulfillment). They have never altered in any way.

مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ فَمِنْهُم مَّن قَضَى نَحْبَهُ وَمِنْهُم مَّن يَنتَظِرُ وَمَا بَدَّلُوا تَبْدِيلاً
