The Quran

وَيَومَ يَقولُ نادوا شُرَكائِيَ الَّذينَ زَعَمتُم فَدَعَوهُم فَلَم يَستَجيبوا لَهُم وَجَعَلنا بَينَهُم مَوبِقًا

Muhammad Asad

Hence, [bear in mind] the Day on which He will say, "Call [now] unto those beings whom you imagined to have a share in My divinity!"¹ - whereupon they will invoke them, but those [beings] will not respond to them: for We shall have placed between them an unbridgeable gulf.²

Lit., "those partners of Mine whom you supposed [to exist]": see note 15 on 6:22.
Or: "a gulf [or "a barrier"] of perdition": an allusion to the wide gulf of unreality that separates those sinners from the blasphemous figments of their imagination or, more probably, the gulf that separates them from the saintly persons whom they were wont to worship despite the fact that the latter had never made any claim to divine status (Zamakhshari and Razi in one of their alternative interpretations, with specific mention of Jesus and Mary).
