- qrTs (if it is not found in the link above)
The root qrTs (ق ر ط س) occurs 2 times in Quran, in 1 derived forms:
But even if we had sent down unto thee [O Prophet] a writing on paper, and they had touched it with their own hands - those who are bent on denying the truth would indeed have said, "This is clearly nothing but a deception!"
For, no true understanding of God have they when they say, "Never has God revealed anything unto man." Say: "Who has bestowed from on high the divine writ which Moses brought unto men as a light and a guidance, [and] which you treat as* [mere] leaves of paper, making a show of them the while you conceal [so] much - although you have been taught [by it] what neither you nor your forefathers had ever known?"* Say: "God [has revealed that divine writ]!" - and then leave them to play at their vain talk.
