Al-Furqan - 25:6

قُلْ أَنزَلَهُ الَّذِي يَعْلَمُ السِّرَّ فِي السَّمَاوَاتِ وَالْأَرْضِ إِنَّهُ كَانَ غَفُورًا رَّحِيمًا
[25:6]
Say: He has revealed it Who knows the secret in the heavens and the earth; surely He is ever Forgiving, Merciful.
Say: "The (Qur'an) was sent down by Him who knows the mystery (that is) in the heavens and the earth: verily He is Oft-Forgiving, Most Merciful."
Say (unto them, O Muhammad): He who knoweth the secret of the heavens and the earth hath revealed it. Lo! He ever is Forgiving, Merciful.
