The word(s) "slandering" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

If they had said: "We hear and we obey: hear thou, and look at us" it had been better for them, and more upright. But Allah hath cursed them for their disbelief, so they believe not, save a few.

(2) Woe unto every slandering traducer,
