Surah Al-Hajj, Verse 58

وَٱلَّذِينَ هَاجَرُواْ فِي سَبِيلِ ٱللَّهِ ثُمَّ قُتِلُوٓاْ أَوۡ مَاتُواْ لَيَرۡزُقَنَّهُمُ ٱللَّهُ رِزۡقًا حَسَنٗاۚ وَإِنَّ ٱللَّهَ لَهُوَ خَيۡرُ ٱلرَّٰزِقِينَ٥٨

wa-alladhīna hājarū fī sabīli l-lahi thumma qutilū aw mātū layarzuqannahumu l-lahu riz'qan ḥasanan wa-inna l-laha lahuwa khayru l-rāziqīna

And those who emigrated for the cause of Allāh and then were killed or died - Allāh will surely provide for them a good provision. And indeed, it is Allāh who is the best of providers.
