Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Allah, the Mighty and Majestic, divided goodness into ten parts; He placed nine parts in al-Sham and the remaining one part in the rest of the earth. And He divided evil into ten parts as well; He placed one part of it in al-Sham and the rest in the rest of the earth."
