If Allah were to punish men for their wrong-doing, He would not leave, on the (earth), a single living creature: but He gives them respite for a stated Term: When their Term expires, they would not be able to delay (the punishment) for a single hour, just as they would not be able to anticipate it (for a single hour). (61)
Tafsir
One way of dealing with transgression is immediately to seize upon the transgressor and punish him severely. But this is not the way of God. If God acted in this way, nobody would be left on the face of the earth. God has given a definite period of respite (ila ajalim musamma) to every person and every community. During this period God gives man the opportunity to listen to the voice of his conscience or to an external warning and to reform himself. This applies likewise to communities. As soon as people reform themselves, all their past crimes are pardoned: it is as if they had started a new life. Just as God has taken it upon Himself not to seize upon anybody during the period of respite, He has similarly taken it upon Himself after the expiry of this period to necessarily seize upon people. After that no individual or community will be given any further opportunity for reform or repentance.
