Musannaf Ibn Abi Shaybah 32529 — Book of Dreams

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Dreams are of three kinds. Some dreams are glad tidings from Allah Almighty, some dreams are the talk of the heart, and some dreams are a frightening from Satan. When any of you sees a good dream, let him relate it if he wishes, and when he sees a displeasing dream, let him tell no one, and let him stand and pray."
