وَما لَكُم أَلّا تُنفِقوا في سَبيلِ اللَّهِ وَلِلَّهِ ميراثُ السَّماواتِ وَالأَرضِ ۚ لا يَستَوي مِنكُم مَن أَنفَقَ مِن قَبلِ الفَتحِ وَقاتَلَ ۚ أُولـٰئِكَ أَعظَمُ دَرَجَةً مِنَ الَّذينَ أَنفَقوا مِن بَعدُ وَقاتَلوا ۚ وَكُلًّا وَعَدَ اللَّهُ الحُسنىٰ ۚ وَاللَّهُ بِما تَعمَلونَ خَبيرٌ

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.
