It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) prayed twice: "O Allah! Grant blessings in our Sham and in our Yemen." A man submitted: "O Messenger of Allah! Pray for our East as well." The Prophet (peace and blessings be upon him) said: "From there the horn of Satan rises, and nine out of ten parts of evil come from there."
