The word(s) "decency" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Pickthal translation.

(1) Such of you as die and leave behind them wives, they (the wives) shall wait, keeping themselves apart, four months and ten days. And when they reach the term (prescribed for them) then there is no sin for you in aught that they may do with themselves in decency. Allah is informed of what ye do.

(2) And there may spring from you a nation who invite to goodness, and enjoin right conduct and forbid indecency. Such are they who are successful.

(3) Ye are the best community that hath been raised up for mankind. Ye enjoin right conduct and forbid indecency; and ye believe in Allah. And if the People of the Scripture had believed it had been better for them. Some of them are believers; but most of them are evil-livers.

(4) They believe in Allah and the Last Day, and enjoin right conduct and forbid indecency, and vie one with another in good works. These are of the righteous.
