The Messenger of Allah ﷺ said, "I saw that the pillar of the Book was pulled out from beneath my pillow. I followed it with my gaze, and there it was, a brilliant light carried toward Syria. Indeed, when tribulation occurs, faith will be in Syria."
قال رسول الله ﷺ: رأيت أن عمود الكتاب انتزع من تحت وسادتي، فأتبعته بصري، فإذا هو نور ساطع فعمد به إلى الشام ألا وإن الإيمان إذا وقعت الفتنة بالشام.
Fasawi narrated it in Marifa wal-Tarikh (2/523), and Hakim graded it sahih (4/509), both through routes from Saeed bin Abdul-Aziz (who is Tanukhi), from Yunus bin Maysara bin Halabas, from Abdullah bin Amr bin As, who mentioned it. Its chain is sahih. As for Hakim's statement, "sahih according to the standard of the two sheikhs," this is not correct, for Yunus bin Maysara bin Halabas is not among the narrators of the two sheikhs, though he is trustworthy.Ahmad (17775) and Tabarani in Musnad Shamiyin (1357) narrated it through another route, both through Ismail bin Ayyash, from Abdul-Aziz bin Ubaydullah, from Abdullah bin Harith, who said, I heard Amr bin As say something similar. Abdul-Aziz bin Ubaydullah is Ibn Hamza bin Suhayb Himsi, whom Ibn Main, Abu Zura, Nasai, and others graded daif.However, Fasawi narrated it in Marifa wal-Tarikh (2/523) from Abdullah bin Yusuf, who said, Muhammad bin Muhajir told us, from Abbas bin Salim, from Madrak bin Abdullah, or from Abu Madrak, who said, We went on campaign with Muawiya and Amr to Egypt, and we made camp at a stopping place. Amr said to Muawiya, "Commander of the Faithful, will you permit me to stand and address the people?" So he gave him permission, and he stood leaning on his bow, praised Allah and extolled Him, then said, "I heard the Messenger of Allah ﷺ say, 'I saw in a dream that the pillar of the Book was carried out from beneath my pillow, so I followed it with my eyes, and it turned into something like a pillar of light, and it was taken toward Syria. Take heed, faith, when turmoil occurs, will be in Syria time and again.'"Madrak bin Abdullah is Azdi, of whom Daraqutni said, "unknown," as stated in Mizan.
