The word(s) "forefathers" appears 8 time(s) in 8 verse(s) in Quran in Mohsin Khan translation.

(1) So when you have accomplished your Manasik , remember Allah as you remember your forefathers or with a far more remembrance. But of mankind there are some who say: "Our Lord! Give us (Your Bounties) in this world!" and for such there will be no portion in the Hereafter.

(2) "Indeed we were promised this - we and our forefathers before (us), verily, these are nothing but tales of ancients."

(3) And when he attained his full strength, and was perfect (in manhood), We bestowed on him Hukm (Prophethood and right judgement of the affairs) and religious knowledge [of the religion of his forefathers i.e. Islamic Monotheism]. And thus do We reward the Muhsinun (i.e. good doers. See the footnote of V.9:120).

(4) In order that you may warn a people whose forefathers were not warned, so they are heedless.

(5) "Allah, your Lord and the Lord of your forefathers?"

(6) La ilaha illa Huwa (none has the right to be worshipped but He). It is He Who gives life and causes death - your Lord and the Lord of your forefathers.

(7) "Then bring back our forefathers, if you speak the truth!"

(8) "And also our forefathers?"
