The word(s) "bitanah" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) O you who believe! Take not as (your) bitanah (advisors, consultants, protectors, helpers, friends) those outside your religion (pagans, Jews, Christians, and hypocrites) since they will not fail to do their best to corrupt you. They desire to harm you severely. Hatred has already appeared from their mouths, but what their breasts conceal is far worse. Indeed We have made plain to you the Ayat (proofs, evidence, verses) if you understand.

(2) Do you think that you shall be left alone while Allah has not yet tested those among you who have striven hard and fought and have not taken Walijah [(bitanah - helpers, advisors and consultants from disbelievers, pagans.) giving openly to them their secrets] besides Allah, and His Messenger, and the believers. Allah is Well-Acquainted with what you do.
