Silsilah as-Sahihah 315 — Prophetic hadith is proof

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Beware! The trial (fitnah) is here, beware! The trial is here (he said this two or three times), from here the edge of the head of Satan will emerge." While saying this, he pointed towards the east or Iraq.
