﴿ وَمَا كُنتَ بِجَانِبِ ٱلطُّورِ إِذْ نَادَيْنَا وَلَٰكِن رَّحْمَةًۭ مِّن رَّبِّكَ لِتُنذِرَ قَوْمًۭا مَّآ أَتَىٰهُم مِّن نَّذِيرٍۢ مِّن قَبْلِكَ لَعَلَّهُمْ يَتَذَكَّرُونَ ﴾

“And neither wert thou present on the slope of Mount Sinai when We called out [to Moses]: but [thou, too, art sent] as an act of thy Sustainer’s grace, to warn people to whom no warner has come before thee, so that they might bethink themselves [of Us];”

(And thou wast not beside the Mount) of Zubayr (when We did call) Moses; and it is also said this means: when We called your nation; (but) We taught you and sent you as (a mercy) a blessing and a favour (from thy Lord) for He sent Gabriel to you with the Qur'an containing the events of the people of old (that thou mayst warn) by means of the Qur'an (a folk unto whom no warner came before thee) no warning messenger came to the people of Quraysh before, (that haply they may give heed) that haply they may take admonition and, hence, believe.
