He who played Nardashir (a game similar to backgammon) is like one who dyed his hand with the flesh and blood of swine.
Sahih Muslim Book 41, Hadith 11
← Previous Hadith We were going with Allah's Messenger (ﷺ). As we reached the place (known as) `Arj there met (us) a poet who had been reciting poetry. Thereupon Allah's Messenger (ﷺ) said: Catch the satan or detain the satan, for filling the belly of a man with pus is better than stuffing his brain with poetry.

Sahih Muslim Book 41, Hadith 10 Next Hadith → I used to see dreams (and was so much perturbed) that I began to quiver and have temperature, but did not cover myself with a mantle. I met Abu Qatada and made a mention of that to him. He said: I heard Allah's Messenger (ﷺ) as saying: A good vision comes from Allah and a (bad) dream (hulm) from devil. So when one of you sees a bad dream (hulm) which he does not like, he should spit on his left side thrice and seek refuge with Allah from its evil; then it will not harm him.
