(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 if We please We would have made you know them so that you would certainly have recognized them by their marks and most certainly you can recognize them by the intent of (their) speech; and Allah knows your deeds.
