The word(s) "lightening" appears 6 time(s) in 6 verse(s) in Quran in Saheeh International translation.

(1) Then if they deny you, [O Muhammad] - so were messengers denied before you, who brought clear proofs and written ordinances and the enlightening Scripture.

(2) It is He who shows you lightening, [causing] fear and aspiration, and generates the heavy clouds.

(3) And of the people is he who disputes about Allah without knowledge or guidance or an enlightening book [from Him],

(4) Do you not see that Allah drives clouds? Then He brings them together, then He makes them into a mass, and you see the rain emerge from within it. And He sends down from the sky, mountains [of clouds] within which is hail, and He strikes with it whom He wills and averts it from whom He wills. The flash of its lightening almost takes away the eyesight.

(5) Do you not see that Allah has made subject to you whatever is in the heavens and whatever is in the earth and amply bestowed upon you His favors, [both] apparent and unapparent? But of the people is he who disputes about Allah without knowledge or guidance or an enlightening Book [from Him].

(6) And if they deny you - then already have those before them denied. Their messengers came to them with clear proofs and written ordinances and with the enlightening Scripture.
