Compare 28:46 and 32:3

28:46 · Al-Qasas · Juz 20

وَمَا كُنتَ بِجَانِبِ ٱلطُّورِ إِذْ نَادَيْنَا وَلَـٰكِن رَّحْمَةً مِّن رَّبِّكَ لِتُنذِرَ قَوْمًا مَّآ أَتَىٰهُم مِّن نَّذِيرٍ مِّن قَبْلِكَ لَعَلَّهُمْ يَتَذَكَّرُونَ

And you were not at the side of Mount Ṭûr when We called out ˹to Moses˺. But ˹you have been sent˺ as a mercy from your Lord to warn a people to whom no warner has come before you, so perhaps they may be mindful.

32:3 · As-Sajda · Juz 21

أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۚ بَلْ هُوَ ٱلْحَقُّ مِن رَّبِّكَ لِتُنذِرَ قَوْمًا مَّآ أَتَىٰهُم مِّن نَّذِيرٍ مِّن قَبْلِكَ لَعَلَّهُمْ يَهْتَدُونَ

Or do they say, “He has fabricated it!”? No! It is the truth from your Lord in order for you to warn a people to whom no warner has come before you, so they may be ˹rightly˺ guided.
