Qur'an 4:100

۞ وَمَن يُهَاجِرْ فِى سَبِيلِ ٱللَّهِ يَجِدْ فِى ٱلْأَرْضِ مُرَٰغَمًا كَثِيرًا وَسَعَةً ۚ وَمَن يَخْرُجْ مِنۢ بَيْتِهِۦ مُهَاجِرًا إِلَى ٱللَّهِ وَرَسُولِهِۦ ثُمَّ يُدْرِكْهُ ٱلْمَوْتُ فَقَدْ وَقَعَ أَجْرُهُۥ عَلَى ٱللَّهِ ۗ وَكَانَ ٱللَّهُ غَفُورًا رَّحِيمًا

Whoso migrateth for the cause of Allah will find much refuge and abundance in the earth, and whoso forsaketh his home, a fugitive unto Allah and His messenger, and death overtaketh him, his reward is then incumbent on Allah. Allah is ever Forgiving, Merciful.
