Surah Al-Qalam, ayah 39

أَمۡ لَكُمۡ أَيۡمَٰنٌ عَلَيۡنَا بَٰلِغَةٌ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِ إِنَّ لَكُمۡ لَمَا تَحۡكُمُونَ ٣٩

Am lakum aymānun 'alaynā bālighatun ilā yawmil-qiyāmati inna lakum lamā tahkumūn

Or do you have oaths [binding] upon Us, extending until the Day of Resurrection, that indeed for you is whatever you judge?
