O Zayn! Such souls as comply with the injunction of God prescribed in the Book are regarded as most excellent in the same estimation of God. There can be no doubt whatsoever is revealed from the heaven of divine commandment is by virtue of His wisdom and is in the best interests of the people themselves. Moreover, although these insignificant amounts are not worthy of mention, they are well pleasing, since the donors offer them for the sake of God. If the offering be but a single grain it is regarded as the crowning glory of all the harvests of the world.
