2 verses have
assumptions
in Edition Clear Qur'an by Talal Itani / Yunus (Jonas)

10:36Most of them follow nothing but assumptions; and assumptions avail nothing against the truth. God is fully aware of what they do.

10:66Certainly, to God belongs everyone in the heavens and everyone on earth. Those who invoke other than God do not follow partners; they follow only assumptions, and they only guess.
