COMMENTARY on 29:63
A. Yusuf Ali:

Translation:
And if indeed you ask them 3496 who it is that sends down rain from the sky, and gives life therewith to the earth after its death, they will certainly reply, "(Allah)!" Say, "Praise be to Allah." But most of them understand not.
Commentary:

3496  In 29:61 above, the point was that there is a certain type of man that realises the power of Allah, but yet goes after false ideas and false worship. Here the point is that there is another type of man to whom the goodness of Allah is made clear by rain and the gifts of nature and who realises the daily, seasonal, and secular changes which evidence Allah's goodness in giving us life (physical and spiritual) and reviving us after we seem to die,-and who yet fails to draw the right conclusion from it and to make his own life true and beautiful, so that when his period of probation in this transitory life is ended, he can enter into his eternal heritage. Having come so far such men fail at the crucial stage. At that stage they ought to have praised and glorified Allah, and accepted His Grace and Light, but they show their want of true understanding by failing to profit by Allah's gifts.
