The word(s) "sly" appears 8 time(s) in 8 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Surely the Safa and the Marwa are among the signs appointed by Allah; so whoever makes a pilgrimage to the House or pays a visit (to it), there is no blame on him if he goes round them both; and whoever does good spontaneously, then surely Allah is Grateful, Knowing.

(2) For a certain number of days; but whoever among you is sick or on a journey, then (he shall fast) a (like) number of other days; and those who are not able to do it may effect a redemption by feeding a poor man; so whoever does good spontaneously it is better for him; and that you fast is better for you if you know.

(3) Let it not deceive you that those who disbelieve go to and fro in the cities fearlessly.

(4) And it did not beseem your Lord to have destroyed the towns tyrannously, while their people acted well.

(5) So when she heard of their sly talk she sent for them and prepared for them a repast, and gave each of them a knife, and said (to Yusuf): Come forth to them. So when they saw him, they deemed him great, and cut their hands (in amazement), and said: Remote is Allah (from imperfection); this is not a mortal; this is but a noble angel.

(6) He said: You shall sow for seven years continuously, then what you reap leave it in its ear except a little of which you eat.

(7) Allah sets forth an example to those who disbelieve the wife of Nuh and the wife of Lut: they were both under two of Our righteous servants, but they acted treacherously towards them so they availed them naught against Allah, and it was said: Enter both the fire with those who enter.

(8) And Firon and those before him and the overthrown cities continuously committed sins.
