Chapter 3: Surat Aal-'Imran (The House 'Imran), verse 113-117

Translation:
Yet they are not all alike. There are among the People of the Book some upright men who all night long recite the revelations of God and worship Him; who believe in God and the Last Day; who enjoin justice and forbid and vie with each other in good works. These are righteous men: whatever good they do, its reward shall not be denied them. God well knows the righteous. As for the unbelievers, neither their riches nor their children shall in the least protect them from God's scourge. They are the heirs of the Fire, and there they shall remain for ever. The wealth they spend in this world is like freezing wind that smites the tillage of men who have wronged themselves, laying it waste. God is not unjust to them; they are unjust to their own souls. (113-117)
Commentary:
‘Hastening
in good works’ here refers to the action of the People of the Book (believers
in former revealed scriptures) of their immediate recognition and acceptance, in
all humility, of the divine truth as proclaimed from the lips of the Last
Prophet. At that time there was the religion of Moses, on the one hand, invested
with all the strength of historical grandeur and sanctity of traditions. On the
other hand stood the religion of Muhammad (Peace be upon him) which had yet to
receive the force of argument and historical grandeur and traditional sanctity
to support it. This difference between their religion and the religion of the
Prophet of the time posed the greatest obstacle to the acknowledgment of the
contemporary Prophet’s religion. Yet they managed to succeed in overcoming
this obstacle and welcomed the religion of the contemporary Prophet.
The
love of wealth and children becomes an obstacle in accepting a religion which
entails all kinds of sacrifices. However, by demonstrating some
showy/ostentatious kinds of actions he thinks/presumes that he has been adhering
to the religion of God. But just as a gust of chill air/frost ravages the whole
harvest so the tempest of Qiyamah (Last Day) will render their ostentatious acts
valueless. There were some people among the Jews who had believed in the Prophet
of Islam. A few God-fearing people are more precious in the eyes of God than a
crowd (of ungodly people).
