Al-Furqan 25:6

قُلْ أَنزَلَهُ ٱلَّذِى يَعْلَمُ ٱلسِّرَّ فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ إِنَّهُۥ كَانَ غَفُورًا رَّحِيمًا

Qul anzalahu alladhī yaʿlamu l-sira fī l-samāwāti wal-arḍi innahu kāna ghafūran raḥīman

Say, [O Muḥammad], "It has been revealed by He who knows [every] secret within the heavens and the earth. Indeed, He is ever Forgiving and Merciful."
