It was said in the last verse (64) that, for the friends of Allah, there is the good news in the worldly life and in the Hereafter. As for the good news of the Hereafter, it will come at the time of death when the spirit of the deceased will be taken to Allah. At that time, he will hear the good news of Paradise being for him. Then, on the day of Qiyamah, when he rises from his grave, he will receive the good news of being welcome to Paradise. This is similar to what al-Tabarani has reported from Sayyidna Ibn ` Umar ؓ narrates that the Holy Prophet ﷺ said: ` People who recite: لا إلہ إلا اللہ (la ilaha illallah: There is no god but Allah) will not experience any fright at the time of death, nor inside the grave, nor at the time they rise from it. This is as if my eyes are seeing the scenario of that time when these people will, shaking the dust off, rise from their graves, saying: الْحَمْدُ لِلَّـهِ الَّذِي أَذْهَبَ عَنَّا الْحَزَنَ (Praised is Allah who has removed from us [ all ] grief - 35:34) '
Acceptance of thinking which breaks fresh ground is always at the cost of the individual having to face numerous unforeseen problems in his society. That is why elderly people exercise caution in accepting any new idea. For a number of reasons elderly people are overwhelmed by a variety of considerations. In spite of admitting the correctness of a new idea, they are unable to proceed further and support it. But the younger generation are generally free from such considerations. So it has always happened throughout history that only those who have not yet attained old age have gone ahead and accepted a new and revolutionary call. This happened likewise in the case of Moses. The youth supporting Moses, on the one hand, risked the retribution of Pharaoh. On the other, they received no encouragement from the elders of their own community. Though these elders accepted the prophethood of Moses, they looked to their own interests, and did not want their sons and daughters to give enthusiastic support to Moses and thus incur the wrath of Pharaoh as a result. However, the existence of such a state of affairs does not call for people to sit quietly, without taking any counter measures. They should keep in view God’s support and favour, rather than human opposition. Relying on God, they should rise in defence of that Truth which they personally found impossible to support.
