وَٱلَّذِينَ هَاجَرُوا۟ فِى سَبِيلِ ٱللَّهِ ثُمَّ قُتِلُوٓا۟ أَوْ مَاتُوا۟ لَيَرْزُقَنَّهُمُ ٱللَّهُ رِزْقًا حَسَنًۭا ۚ وَإِنَّ ٱللَّهَ لَهُوَ خَيْرُ ٱلرَّٰزِقِينَ
Those who fled their homes for the cause of Allah and then were slain or died, Allah verily will provide for them a good provision. Lo! Allah, He verily is Best of all who make provision.
