Hadith 7390
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "There are one hundred levels in Paradise which Allah Almighty has prepared for those who strive in His path. The distance between two of these levels is as great as that between the heavens and the earth. When you ask (from Allah), then ask for Jannat al-Firdaws, for it is the middle and highest part of Paradise, and above it is the Throne, and from it the rivers of Paradise flow."
