Surah Al-Qasas 28:46

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 the mount when We called [Moses] but [were sent] as a mercy from your Lord to warn a people to whom no warner had come before you that they might be reminded.

Translation: Saheeh International

Tafsir

And you were not on the side of the Mount when We called out to Moses to take the Scripture earnestly; but We have sent you as a mercy from your Lord that you may warn a people to whom no warner came before you — these are the people of Mecca — and that perhaps they may remember they may be admonished.
