Is it permissible to claim knowledge of the future, and how can one explain the precise knowledge some individuals have of future matters, as occurred with dream interpreters like Ibn Sirin, and the perspicacity of Ibn Taymiyyah mentioned by Ibn al-Qayyim al-Jawziyyah? And is the objection to the principle of knowing the future, or to the method by which this knowledge is acquired?

There is no objection to some people being informed of the relative unseen through inspiration, sagacity (firasah), or true dreams, and asking Allah to be informed of it. For Allah informs whomever He wills of His servants of such matters, as stated in the Hadith: "Among the nations before you, there were people who were 'muhaddathun' (inspired). If there is anyone like them in my nation, it is 'Umar." The 'muhaddathun' are those inspired individuals through whose tongues Allah causes some unseen matters to be spoken. A true dream involves foretelling a future event, which then occurs as seen by the dreamer. In the Hadith: "The dream of a believer is one of forty-six parts of prophethood," and "Nothing remains of the glad tidings of prophethood except the righteous dream, which a Muslim sees or is seen for him."
