57:10
وَمَا لَكُمْ أَلَّا تُنفِقُوا۟ فِى سَبِيلِ ٱللَّهِ وَلِلَّهِ مِيرَٰثُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ لَا يَسْتَوِى مِنكُم مَّنْ أَنفَقَ مِن قَبْلِ ٱلْفَتْحِ وَقَـٰتَلَ ۚ أُو۟لَـٰٓئِكَ أَعْظَمُ دَرَجَةً مِّنَ ٱلَّذِينَ أَنفَقُوا۟ مِنۢ بَعْدُ وَقَـٰتَلُوا۟ ۚ وَكُلًّا وَعَدَ ٱللَّهُ ٱلْحُسْنَىٰ ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ
And why do you not spend in the cause of Allah while to Allah belongs the heritage of the heavens and the earth? Not equal among you are those who spent before the conquest [of Makkah] and fought [and those who did so after it]. Those are greater in degree than they who spent afterwards and fought. But to all Allah has promised the best [reward]. And Allah, with what you do, is Acquainted.
