وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَٰنًۭا وَمَا لَيْسَ لَهُم بِهِۦ عِلْمٌۭ ۗ وَمَا لِلظَّٰلِمِينَ مِن نَّصِيرٍۢ
And they worship instead of Allah that for which He hath sent down no warrant, and that whereof they have no knowledge. For evil-doers there is no helper.
Surah Al-Hajj(22:71)

Interpretation of Dreams
Chapter: Night dreams
Narrated `Abdullah bin `Umar:
Allah's Messenger (ﷺ) said, "I saw myself (in a dream) near the Ka`ba last night, and I saw a man with whitish red complexion, the best you may see amongst men of that complexion having long hair reaching his earlobes which was the best hair of its sort, and he had combed his hair and water was dropping from it, and he was performing the Tawaf around the Ka`ba while he was leaning on two men or on the shoulders of two men. I asked, 'Who is this man?' Somebody replied, '(He is) Messiah, son of Mary.' Then I saw another man with very curly hair, blind in the right eye which looked like a protruding out grape. I asked, 'Who is this?' Somebody replied, '(He is) Messiah, Ad-Dajjal.'"
