Sahih: The True Dream is one of the forty-five parts of Prophet-hood.

It was narrated from Abu Hurayrah that the Prophet (peace and blessings of Allah be upon him) said: “Towards the end of time, hardly any dream of a Muslim will be false. The ones who have the truest dreams will be those who are truest in speech. The dream of a Muslim is one of the forty-five parts of Prophet-hood. Dreams are of three types: a good dream which is glad tidings from Allah, a dream from the Shaytan which causes distress, and a dream that comes from what a man is thinking of to himself.” [Muslim; 2263]
