The word(s) "conjectures" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Now, surely, whatever is in the heavens and whatever is in the earth is Allah's; and they do not (really) follow any associates, who call on others besides Allah; they do not follow (anything) but conjectures, and they only lie.

(2) (Some) say: (They are) three, the fourth of them being their dog; and (others) say: Five, the sixth of them being their dog, making conjectures at what is unknown; and (others yet) say: Seven, and the eighth of them is their dog. Say: My Lord best knows their number, none knows them but a few; therefore contend not in the matter of them but with an outward contention, and do not question concerning them any of them.

(3) And they disbelieved in it before, and they utter conjectures with regard to the unseen from a distant place.
