Surah Muhammad, ayah 38

47:38

هَٰٓأَنتُمۡ هَٰٓؤُلَآءِ تُدۡعَوۡنَ لِتُنفِقُواْ فِي سَبِيلِ ٱللَّهِ فَمِنكُم مَّن يَبۡخَلُۖ وَمَن يَبۡخَلۡ فَإِنَّمَا يَبۡخَلُ عَن نَّفۡسِهِۦۚ وَٱللَّهُ ٱلۡغَنِيُّ وَأَنتُمُ ٱلۡفُقَرَآءُۚ وَإِن تَتَوَلَّوۡاْ يَسۡتَبۡدِلۡ قَوۡمًا غَيۡرَكُمۡ ثُمَّ لَا يَكُونُوٓاْ أَمۡثَٰلَكُم ٣٨

Hā'antum hā'ulā'i tud'awna litunfiqū fī sabīlillāhi faminkum man yabkhalu waman yabkhal fa innamā yabkhalu 'an nafsihī wallāhul-ghaniyyu wa antumul-fuqarā'u wa in tatawallaw yastabdil qawman ghayrakum thumma lā yakūnū amthālakum

Here you are - those invited to spend in the cause of Allāh - but among you are those who withhold [out of greed]. And whoever withholds only withholds [benefit] from himself; and Allāh is the Free of need, while you are the needy. And if you turn away [i.e., refuse], He will replace you with another people; then they will not be the likes of you.
