The word(s) "invent" appears 55 time(s) in 51 verse(s) in Quran in Muhammad Pickthal translation.

(41) Or say they: He hath invented it? Nay, but it is the Truth from thy Lord, that thou mayst warn a folk to whom no warner came before thee, that haply they may walk aright.

(42) Hath he invented a lie concerning Allah, or is there in him a madness? Nay, but those who disbelieve in the Hereafter are in torment and far error.

(43) And if Our revelations are recited unto them in plain terms, they say: This is naught else than a man who would turn you away from what your fathers used to worship; and they say: This is naught else than an invented lie. Those who disbelieve say of the truth when it reacheth them: This is naught else than mere magic.

(44) We have not heard of this in later religion. This is naught but an invention.

(45) Or say they: He hath invented a lie concerning Allah? If Allah willed, He could have sealed thy heart (against them). And Allah will wipe out the lie and will vindicate the truth by His words. Lo! He is Aware of what is hidden in the breasts (of men).

(46) Or say they: He hath invented it? Say (O Muhammad): If I have invented it, still ye have no power to support me against Allah. He is Best Aware of what ye say among yourselves concerning it. He sufficeth for a witness between me and you. And He is the Forgiving, the Merciful.

(47) Then why did those whom they had chosen for gods as a way of approach (unto Allah) not help them? Nay, but they did fail them utterly. And (all) that was their lie, and what they used to invent.

(48) Or say they: He hath invented it? Nay, but they will not believe!

(49) Then We caused Our messengers to follow in their footsteps; and We caused Jesus, son of Mary, to follow, and gave him the Gospel, and placed compassion and mercy in the hearts of those who followed him. But monasticism they invented - We ordained it not for them - only seeking Allah's pleasure, and they observed it not with right observance. So We give those of them who believe their reward, but many of them are evil-livers.

(50) And who doeth greater wrong than he who inventeth a lie against Allah when he is summoned unto Al-Islam? And Allah guideth not wrongdoing folk.
