Al-Ahqaf 46:10

Say, “What do you think, if this [Qur’an] is really from Allah and yet you reject it, and a witness[4] from the Children of Israel has testified in its favor and believed[5], whereas you persist in arrogance[6]? Indeed, Allah does not guide the wrongdoing people.”

[4] Such as Abdullah ibn Salām, a Jewish scholar, who accepted Islam when the Prophet (ﷺ) emigrated from Makkah to Medina.
[5] Based on information in the Torah testifying his message.
[6] The estimated conclusion could be "...would you not then be unjust and wrongdoer people?"

Say, "Have you considered: if it [i.e., the Qur’ān] was from Allāh, and you disbelieved in it while a witness from the Children of Israel has testified to something similar[1480] and believed while you were arrogant...?"[1481] Indeed, Allāh does not guide the wrongdoing people.

[1480] Based upon information from the Torah.
[1481] The conclusion is estimated to be "...would you not then be the most unjust of people?" or "...in what condition would you then be?"

10. Say: "Tell me! If this (Qur’ân) is from Allâh and you deny it, and a witness from among the Children of Israel (‘Abdullâh bin Salâm رضي الله عنه) testifies that [this Qur’ân is from Allâh (like the Taurât (Torah)], and he believed (embraced Islâm)[2] while you are too proud (to believe)." Verily, Allâh guides not the people who are Zâlimûn (polytheists, disbelievers and wrong-doers).

[2] (V.46:10) See the footnote of (V.5:66).

Bethink you: If it is from Allah and ye disbelieve therein, and a witness of the Children of Israel hath already testified to the like thereof and hath believed, and ye are too proud (what plight is yours)? Lo! Allah guideth not wrong-doing folk.
