The word(s) "superstitions" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) It was not Allah who instituted (superstitions like those of) a slit-ear she-camel, or a she-camel let loose for free pasture, or idol sacrifices for twin-births in animals, or stallion-camels freed from work: It is blasphemers who invent a lie against Allah; but most of them lack wisdom.

(2) They say: "What is in the wombs of such and such cattle is specially reserved (for food) for our men, and forbidden to our women; but if it is still-born, then all have share therein. For their (false) attribution (of superstitions to Allah), He will soon punish them: for He is full of wisdom and knowledge.
