لِتُنذِرَ قَوْمًا مَّا أَتَاهُم مِّن نَّذِيرٍ ( so that you warn a people to whom no warner has come before - Al-Qasas 28:46 ⧉). The expression ` a people' is purported here for the Arabs, who are the progeny of Sayyidna Ismail (علیہ السلام) . No prophet was sent to this ` people' after Sayyidna Ismail علیہ السلام until the Holy Prophet ﷺ was sent. The same subject will follow in Surah Yasin⧉. But this verse Al-Qasas 28:46 ⧉ is not in conflict with the other verse إِن مِّنْ أُمَّةٍ إِلَّا خَلَا فِيهَا نَذِيرٌ (There is no community, but there has come a warner among them - Fatir 35:24 ⧉). What the present verse Al-Qasas 28:46 ⧉ means here is that there was no prophet in ` this people' for a long time after Ismail . But after the arrival of the Holy Prophet ﷺ this void was filled up.
