33. This expression signifies spending one's wealth for the sake of God. Since God has promised to return to man every penny that he spends in His way along with His reward, which will be several-fold, the Qur'an characterizes this spending as a loan to God. This spending is considered a loan provided it is a 'good loan', that is, provided the money spent in the cause of God has been acquired by legitimate means and has been spent in accordance with the laws of God and with sincerity and earnestness.
