4 verses have
whom
in Edition Clear Qur'an by Talal Itani / Al-Kahf (The Cave)

18:17You would have seen the sun, when it rose, veering away from their cave towards the right, and when it sets, moving away from them to the left, as they lay in the midst of the cave. That was one of God’s wonders. He whom God guides is truly guided; but he whom He misguides, for him you will find no directing friend.

18:52On the Day when He will say, “Call on My partners whom you have claimed.” They will call on them, but they will not answer them. And We will place between them a barrier.

18:65Then they came upon a servant of Ours, whom We had blessed with mercy from Us, and had taught him knowledge from Our Own.

18:90Until, when he reached the rising of the sun, he found it rising on a people for whom We had provided no shelter from it.
