The word(s) "mere" appears 24 time(s) in 24 verse(s) in Quran in Muhammad Pickthal translation.

(21) And when Jesus son of Mary said: O Children of Israel! Lo! I am the messenger of Allah unto you, confirming that which was (revealed) before me in the Torah, and bringing good tidings of a messenger who cometh after me, whose name is the Praised One. Yet when he hath come unto them with clear proofs, they say: This is mere magic.

(22) That was because their messengers (from Allah) kept coming unto them with clear proofs (of Allah's Sovereignty), but they said: Shall mere mortals guide us? So they disbelieved and turned away, and Allah was independent (of them). Allah is Absolute, Owner of Praise.

(23) That, when Our revelations are recited unto him, he saith: mere fables of the men of old.

(24) Who, when thou readest unto him Our revelations, saith: (mere) fables of the men of old.
