﴿ وَأَنفِقُوا۟ فِى سَبِيلِ ٱللَّهِ وَلَا تُلْقُوا۟ بِأَيْدِيكُمْ إِلَى ٱلتَّهْلُكَةِ ۛ وَأَحْسِنُوٓا۟ ۛ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُحْسِنِينَ ﴾

“And spend [freely] in God's cause, and let not your own hands throw you into destruction; and persevere in doing good: behold, God loves the doers of good.”

And spend in the way of God in obedience to Him in holy struggle and the like; and cast not your own hands yourselves the bā’ of bi-aydīkum ‘with your hands’ is extra into destruction by withholding funds needed for the struggle or abandoning it altogether because this will give your enemy the advantage over you; but be virtuous by spending etc.; God loves the virtuous that is He rewards them.
