If He should ask you for them and press you, you would withhold, and He would expose your unwillingness.  

إِنْ يَسْأَلْكُمُوهَا فَيُحْفِكُمْ تَبْخَلُوا وَيُخْرِجْ أَضْغَانَكُمْ  

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

هَا أَنْتُمْ هَٰؤُلَاءِ تُدْعَوْنَ لِتُنْفِقُوا فِي سَبِيلِ اللَّهِ فَمِنْكُمْ مَنْ يَبْخَلُ ۖ وَمَنْ يَبْخَلْ فَإِنَّمَا يَبْخَلُ عَنْ نَفْسِهِ ۚ وَاللَّهُ الْغَنِيُّ وَأَنْتُمُ الْفُقَرَاءُ ۚ وَإِنْ تَتَوَلَّوْا يَسْتَبْدِلْ قَوْمًا غَيْرَكُمْ ثُمَّ لَا يَكُونُوا أَمْثَالَكُمْ
