Sahih al-Bukhari 7017

Muhammad ibn Sirin related that Abu Hurayra said, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'When the time [of the Final Hour] approaches, the dream of the believer will hardly ever lie. The dream of the believer is one forty-sixth part of prophethood.' That which is part of prophethood does not lie." Muhammad stated, "I say this." He said that it used to be said, "There are three types of dreams: the chatter of the self, attempts of Shaytan to frighten the dreamer, and good news from Allah. Whoever sees anything he dislikes should not recount it to anyone. He should get up and pray." He said, "He disliked to see iron collars in a dream but he liked fetters." It is said that the fetter represents constancy in the deen. It is related from Ibn Sirin from Abu Hurayra from the Prophet, may Allah bless him and grant him peace. Some of them included all of it in the hadith. The hadith of 'Awf is clearer. Yunus said, "I do not reckon that it is from the Prophet, may Allah bless him and grant him peace, except what he said about fetters." Abu 'Abdullah said, "Ghull is only used for necks.'
