مِّنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ ۖ فَمِنْهُم مَّن قَضَىٰ نَحْبَهُ وَمِنْهُم مَّن يَنتَظِرُ ۖ وَمَا بَدَّلُوا تَبْدِيلًا (23)
(33:23) Among the believers there are those who have remained true to the covenant they made with Allah. Among those some of them have fulfilled their vow and others await the appointed time. *39 They have not changed in the least.
*39) That is, "Someone has already offered his life in the way of Allah, and someone is awaiting the time when he will offer it for the sake of his Faith. "
