The Prophet ﷺ said, "Whoever believes in Allah and His Messenger, establishes the prayer, and fasts Ramadan, it is a right upon Allah to admit him into Paradise, whether he migrates in the path of Allah or remains in the land where he was born."They said, "Messenger of Allah, shall we not inform the people of this?"He replied, "In Paradise there are one hundred ranks which Allah has prepared for those who strive in His path. Between every two ranks is a distance like that between the heavens and the earth. So when you ask Allah, ask Him for al-Firdaws, for it is the middle of Paradise and the highest part of Paradise. Above it is the Throne of the Most Merciful, and from it flow the rivers of Paradise."
عن النبي ﷺ قال: من آمن بالله ورسوله، وأقام الصلاة، وصام رمضان، كان حقا على الله أن يدخله الجنة هاجرفي سبيل الله أو جلس في أرضه التي ولد فيها. قالوا: يا رسول الله افلا ننبئ الناس بذلك. قال: إن في الجنة مائة درجة أعدها الله للمجاهدين في سبيله، كل درجتين ما بينهما كما بين السماء والأرض، فإذا سألتم الله فسلوه الفردوس، فإنه أوسط الجنة، وأعلى الجنة، وفوقه عرش الرحمن، ومنه تفجر أنهار الجنة.
