The word(s) "discourses" appears 9 time(s) in 8 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And when you see those who enter into false discourses about Our communications, withdraw from them until they enter into some other discourse, and if the Shaitan causes you to forget, then do not sit after recollection with the unjust people.

(2) And they do not assign to Allah the attributes due to Him when they say: Allah has not revealed anything to a mortal. Say: Who revealed the Book which Musa brought, a light and a guidance to men, which you make into scattered writings which you show while you conceal much? And you were taught what you did not know, (neither) you nor your fathers. Say: Allah then leave them sporting in their vain discourses.

(3) Like those before you; they were stronger than you in power and more abundant in wealth and children, so they enjoyed their portion; thus have you enjoyed your portion as those before you enjoyed their portion; and you entered into vain discourses like the vain discourses in which entered those before you. These are they whose works are null in this world and the hereafter, and these are they who are the losers.

(4) Or do they think that We do not hear what they conceal and their secret discourses? Aye! and Our apostles with them write down.

(5) So leave them plunging into false discourses and sporting until they meet their day which they are threatened with.

(6) Those who sport entering into vain discourses.

(7) Therefore leave them alone to go on with the false discourses and to sport until they come face to face with that day of theirs with which they are threatened;

(8) And we used to enter into vain discourse with those who entered into vain discourses.
