Quran 68:39 — The Pen (Al-Qalam)

أَم لَكُم أَيمٰنٌ عَلَينا بٰلِغَةٌ إِلىٰ يَومِ القِيٰمَةِ ۙ إِنَّ لَكُم لَما تَحكُمونَ

Or, have you received solemn assurances from us that grant you whatever you wish on the Day of Resurrection?

[68:38] In it, do you find anything you want?

[68:40] Ask them, "Who guarantees this for you?"
