The Family of Imran
ٱلَّذِينَ ٱسْتَجَابُوا۟ لِلَّهِ وَٱلرَّسُولِ مِنۢ بَعْدِ مَآ أَصَابَهُمُ ٱلْقَرْحُ ۚ لِلَّذِينَ أَحْسَنُوا۟ مِنْهُمْ وَٱتَّقَوْا۟ أَجْرٌ عَظِيمٌ
Those [believers] who responded to Allah and the Messenger after injury had struck them. For those who did good among them and feared Allah is a great reward -

فَرِحِينَ بِمَآ ءَاتَىٰهُمُ ٱللَّهُ مِن فَضْلِهِۦ وَيَسْتَبْشِرُونَ بِٱلَّذِينَ لَمْ يَلْحَقُوا۟ بِهِم مِّنْ خَلْفِهِمْ أَلَّا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
Rejoicing in what Allah has bestowed upon them of His bounty, and they receive good tidings about those [to be martyred] after them who have not yet joined them - that there will be no fear concerning them, nor will they grieve.
۞ يَسْتَبْشِرُونَ بِنِعْمَةٍ مِّنَ ٱللَّهِ وَفَضْلٍ وَأَنَّ ٱللَّهَ لَا يُضِيعُ أَجْرَ ٱلْمُؤْمِنِينَ
They receive good tidings of favor from Allah and bounty and [of the fact] that Allah does not allow the reward of believers to be lost -
ٱلَّذِينَ قَالَ لَهُمُ ٱلنَّاسُ إِنَّ ٱلنَّاسَ قَدْ جَمَعُوا۟ لَكُمْ فَٱخْشَوْهُمْ فَزَادَهُمْ إِيمَـٰنًا وَقَالُوا۟ حَسْبُنَا ٱللَّهُ وَنِعْمَ ٱلْوَكِيلُ
Those to whom hypocrites said, "Indeed, the people have gathered against you, so fear them." But it [merely] increased them in faith, and they said, "Sufficient for us is Allah, and [He is] the best Disposer of affairs."
فَٱنقَلَبُوا۟ بِنِعْمَةٍ مِّنَ ٱللَّهِ وَفَضْلٍ لَّمْ يَمْسَسْهُمْ سُوٓءٌ وَٱتَّبَعُوا۟ رِضْوَٰنَ ٱللَّهِ ۗ وَٱللَّهُ ذُو فَضْلٍ عَظِيمٍ
So they returned with favor from Allah and bounty, no harm having touched them. And they pursued the pleasure of Allah, and Allah is the possessor of great bounty.
