Abu Salama reported: 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 Qatadah (RA) 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.
This hadith has been narrated on the authority of Abu Qatadah (RA), but there is no mention of the words of Abu Salama (RA) : "I saw dreams (which perturbed me) but I did not cover myself with a mantle."
Abu Qatadah (RA) reported Allah's Messenger (ﷺ) as saying: A good vision is from Allah and a bad dream (hulm) is from the satan; so if one of you sees anything (in a dream which he dislikes, he should spit on his left side thrice and seek refuge with Allah from its evil, and then it will never harm him. Abu Salama said: I used to see dreams weighing more heavily upon me than a mountain; but since I heard this hadith I don't care for it (its burden).
Abu Qatadah (RA) reported Allah's Messenger (ﷺ) as saying: The good vision are from Allah and the evil dreams are from the satan. If one sees a dream which one does not like, one should spit on one's left side and seek the refuge of Allah from the satan; it will not do one any harm, and one should not disclose it to anyone and if one sees a good vision one should feel pleased but should not disclose it to anyone but whom one loves.
Abu Salama replied: I used to see (such horrible dreams) that I fell ill. I saw Abu Qatadah (RA) who also said: I used to see dreams which made me sick until I heard Allah's Messenger (ﷺ) as saying: Good dreams are from Allah, so if any one of you sees which he likes he should not disclose it to one but who he loves, but if he sees something which he does not like he should spit on his left side thrice and seek refuge with Allah from the mischief of the satan and its mischief (i. e. of the dream), and he should not relate it to anyone, then it would not harm him.
This hadith has been transmitted on the same authority but with this variation that the hadith trarismitted on the authority of Nabra (the words are): One who is better than I informed me, and he was Abu Qatatda, and in the hadith transmitted on the authority of Khalid instead of the word 'bu_us' there is 'dys' or 'yadis', i. e.:" how sad it is".
