22. It will be wrong to conclude from this demand of theirs that the Prophets professed the religion of their people before their appointment to the divine office. This only meant that their people thought so because before their appointment they led a quiet life and did not propagate a new religion nor refuted the religion in vogue at that time. That is why their people were under the wrong impression that the Prophets also professed the religion of their forefathers, and, therefore, accused them of apostasy. The fact, however, is that they had never followed the religion of their mushrik forefathers and were not guilty of apostasy.
23. This was to reassure the Prophets that they should not worry at all about the threat that the disbelievers would banish them from their country, as if to say: We will uproot them from their land, and establish you and your followers firmly in their place.
24. In order to grasp the real significance of these historical events, it should be kept in view that these are being related here as answers to those objections which the disbelievers of Makkah raised before the Prophet (peace be upon him). As the conditions there at the time of the revelation of this Surah were exactly like those of the peoples of the former Prophets, they have been cited here to warn the Quraish along with the other mushriks of Arabia of the consequences, as if to say: The former disbelievers challenged their Messengers and were destroyed and the believers were established in the land. Likewise your future also entirely depends on the attitude you adopt towards the message of your Prophet. If you accept this, you will be allowed to remain in the land of Arabia, and if you reject it you shall be utterly uprooted from here. The subsequent events proved that this prophecy was literally fulfilled within fifteen years after this, for there remained not a single mushrik in the whole of Arabia.
