Sayyiduna Abu Hurayrah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "Whoever believes in Allah and His Messenger, establishes the prayer and fasts in Ramadan, Allah will surely admit him into Paradise, whether he emigrates or stays in the very land where he was born." The Companions (may Allah be pleased with them) said: O Messenger of Allah! Shall we not inform the people of this? He (peace and blessings be upon him) said: "Indeed, in Paradise there are one hundred levels which Allah Almighty has prepared for the mujahidin who strive in His way, and the distance between every two levels is like that between the heaven and the earth. So when you ask Allah, ask Him for Paradise al-Firdaws, for it is the middle and the highest Paradise, above it is the Throne of Allah Almighty, and from it the rivers of Paradise gush forth."
