﴿ وَمَا لَكُمْ أَلَّا تُنفِقُوا۟ فِى سَبِيلِ ٱللَّهِ وَلِلَّهِ مِيرَٰثُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۚ لَا يَسْتَوِى مِنكُم مَّنْ أَنفَقَ مِن قَبْلِ ٱلْفَتْحِ وَقَٰتَلَ ۚ أُو۟لَٰٓئِكَ أَعْظَمُ دَرَجَةًۭ مِّنَ ٱلَّذِينَ أَنفَقُوا۟ مِنۢ بَعْدُ وَقَٰتَلُوا۟ ۚ وَكُلًّۭا وَعَدَ ٱللَّهُ ٱلْحُسْنَىٰ ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌۭ ﴾
“And why should you not spend freely in the cause of God, seeing that God’s [alone] is the heritage of the heavens and the earth? Not equal are those of you who spent and fought [in God’s cause] before the Victory [and those who did not do so]: they are of a higher rank than those who would spend and fight [only] after it - although God has promised the ultimate good to all [who strive in His cause]. and god is aware of that you do.”
