The Messenger of Allah ﷺ said, "Allah has promised me that seventy thousand of my nation will enter Paradise without reckoning."Yazid bin al-Akhnas as-Sulami said, "By Allah, those are no more in your nation than reddish flies among ordinary flies."The Messenger of Allah ﷺ replied, "My Lord
had promised me seventy thousand, with every thousand accompanied by another seventy thousand, and He has granted me three additional handfuls."Someone asked, "How vast is your Pool, Prophet of Allah?"He answered, "Like the distance between Aden and Amman, and even wider, and even wider," gesturing with his hand. "It has two spouts pouring into it, one of gold and one of silver."The questioner asked, "What is your Pool like, Prophet of Allah?"He said, "Whiter than milk, sweeter in taste than honey, and more fragrant than musk. Whoever drinks from it will never thirst again, and his face will never be blackened."
حدثنا عصام بن خالد حدثني صفوان بن عمرو عن سليم بن عامر الخبائري وأبي اليمان الهوزني
أن رسول الله ﷺ قال إن الله عز وجل وعدني أن يدخل من أمتي الجنة سبعين ألفا بغير حساب فقال يزيد بن الأخن السلمي والله ما أولئك في أمتك إلا كالذباب الأصهب في الذبان فقال رسول الله ﷺ كان ربي عز وجل قد وعدني سبعين ألفا مع كل ألف سبعون ألفا وزادني ثلاث حثيات قال فما سعة حوضك يا نبي الله قال كما بين عدن إلى عمان وأوسع وأوسع يشير بيده قال فيه مثعبان من ذهب وفضة قال فما حوضك يا نبي الله قال أشد بياضا من اللبن وأحلى مذاقة من العسل وأطيب رائحة من المسك من شرب منه لم يظمأ بعدها ولم يسود وجهه أبدا
