Yusuf bin 'Abdullah bin al-Harith يوسف بن عبد الله بن الحارث · Interpretation of Dreams

“(Good) dreams come from Allah and (bad) dreams come from Satan, so if anyone of you sees something that he dislikes, let him spit dryly to his left three times, and seek refuge with Allah from the accursed Satan three times, and turn over onto his other side.”
