The word(s) "conjecture" appears 6 time(s) in 5 verse(s) in Quran in Muhammad Pickthal translation.

(1) And because of their saying: We slew the Messiah, Jesus son of Mary, Allah's messenger - they slew him not nor crucified him, but it appeared so unto them; and lo! those who disagree concerning it are in doubt thereof; they have no knowledge thereof save pursuit of a conjecture; they slew him not for certain.

(2) Most of them follow not but conjecture. Assuredly conjecture can by no means take the place of truth. Lo! Allah is Aware of what they do.

(3) Lo! is it not unto Allah that belongeth whosoever is in the heavens and whosoever is in the earth? Those who follow aught instead of Allah follow not (His) partners. They follow only a conjecture, and they do but guess.

(4) And when it was said: Lo! Allah's promise is the truth, and there is no doubt of the Hour's coming, ye said: We know not what the Hour is. We deem it naught but a conjecture, and we are by no means convinced.

(5) Accursed be the conjecturers
