The word(s) "roof" appears 247 time(s) in 241 verse(s) in Quran in Mohsin Khan translation.

(161) And We said: "Go you both to the people who have denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)." Then We destroyed them with utter destruction.

(162) And for each (of them) We put forward examples (as proofs and lessons), and each (of them) We brought to utter ruin (because of their disbelief and evil deeds).

(163) And those who, when they are reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, fall not deaf and blind thereat.

(164) Verily, in this is an Ayah (proof or sign), yet most of them (polytheists, pagans who do not believe in Resurrection) are not believers.

(165) Verily in this is indeed a sign (or a proof), yet most of them are not believers.

(166) But when Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) came to them, clear to see, they said: "This is a manifest magic."

(167) Is not He (better than your so-called gods) Who originates creation, and shall thereafter repeat it, and Who provides for you from heaven and earth? Is there any ilah (god) with Allah? Say: "Bring forth your proofs, if you are truthful."

(168) Nor can you lead the blind out of their error. You can only make to hear those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and who have submitted (themselves to Allah in Islam as Muslims).

(169) And (remember) the Day when We shall gather out of every nation a troop of those who denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and (then) they (all) shall be driven (to the place of reckoning),

(170) Till, when they come (before their Lord at the place of reckoning), He will say: "Did you deny My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) whereas you comprehended them not by knowledge (of their truth or falsehood), or what (else) was it that you used to do?"
