17:85
وَيَسۡـَٔلُونَكَ عَنِ ٱلرُّوحِۖ قُلِ ٱلرُّوحُ مِنۡ أَمۡرِ رَبِّي وَمَآ أُوتِيتُم مِّنَ ٱلۡعِلۡمِ إِلَّا قَلِيلٗا ٨٥
Wa Yas'alūnaka `Ani Ar-Rūĥi ۖ Quli Ar-Rūĥu Min 'Amri Rabbī Wa Mā 'Ūtītum Mina Al-`Ilmi 'Illā Qalīlāan
And they ask you, [O Muhammad], about the soul. Say, "The soul is of the affair of my Lord. And mankind have not been given of knowledge except a little."
