(Alms are) for the poor who are confined in the way of Allah-- they cannot go about in the land; the ignorant man thinks them to be rich on account of (their) abstaining (from begging); you can recognise them by their mark; they do not beg from men importunately; and whatever good thing you spend, surely Allah knows it.

And prepare against them what force you can and horses tied at the frontier, to frighten thereby the enemy of Allah and your enemy and others besides them, whom you do not know (but) Allah knows them; and whatever thing you will spend in Allah's way, it will be paid back to you fully and you shall not be dealt with unjustly.
