Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) reports this saying of the Prophet (peace and blessings be upon him): "A good dream is one part of the seventy parts of prophethood. Whoever sees something good should praise Allah Almighty and mention it; and whoever sees something else (that is, an unpleasant dream) should seek refuge in Allah from the evil of his dream and not mention it, and then it will not harm him."
Ahmad and al-Tabarani (in al-Mu'jam al-Awsat) recorded it, and its narrators are the narrators of the Sahih, except Sulayman bin Dawud al-Hashimi, who is thiqah (trustworthy).
