The word(s) "grave" appears 27 time(s) in 27 verse(s) in Quran in Mohsin Khan translation.

(1) And because of their (Jews) disbelief and uttering against Maryam (Mary السلام عليهما) a grave false charge (that she has committed illegal sexual intercourse);

(2) It is He Who has created you from a single person (Adam), and has given you a place of residing (on the earth or in your mother's wombs) and a place of storage [in the earth (in your graves) or in your father's loins]. Indeed, We have explained in detail Our revelations (this Qur'an) for people who understand.

(3) And never (O Muhammad صلى الله عليه وسلم) pray (funeral prayer) for any of them (hypocrites) who dies, nor stand at his grave. Certainly they disbelieved in Allah and His Messenger, and died while they were Fasiqun (rebellious, - disobedient to Allah and His Messenger صلى الله عليه وسلم).

(4) And on the Day when He shall gather (resurrect) them together, (it will be) as if they had not stayed (in the life of this world and graves) but an hour of a day. They will recognise each other. Ruined indeed will be those who denied the Meeting with Allah, and were not guided.

(5) And no moving (living) creature is there on earth but its provision is due from Allah. And He knows its dwelling place and its deposit (in the uterus, grave). All is in a Clear Book (Al-Lauh Al-Mahfuz - the Book of Decrees with Allah).

(6) They said: "O Salih! You have been among us as a figure of good hope (and we wished for you to be our chief) till this [new thing which you have brought that we leave our gods and worship your God (Allah) Alone]! Do you (now) forbid us the worship of what our fathers have worshipped? But we are really in grave doubt as to that to which you invite us (monotheism)."

(7) Indeed, We gave the Book to Musa (Moses), but differences arose therein, and had it not been for a Word that had gone forth before from your Lord, the case would have been judged between them, and indeed they are in grave doubt concerning it (this Qur'an).

(8) Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)."

(9) And the true promise (Day of Resurrection) shall draw near (of fulfillment). Then (when mankind is resurrected from their graves), you shall see the eyes of the disbelievers fixedly staring in horror. (They will say): "Woe to us! We were indeed heedless of this - nay, but we were Zalimun (polytheists and wrong-doers)."

(10) And surely, the Hour is coming, there is no doubt about it; and certainly, Allah will resurrect those who are in the graves.
