He mentioned the hadith of the Night Journey and Ascension, in which it was said, "The Lote Tree of the Utmost Boundary was raised up for me. Its fruits were like the large jars of Hajar, and its leaves were like the ears of elephants. At its base were four rivers, two hidden and two visible. I asked Jibreel about them, and he replied, 'As for the two hidden ones, they are in Paradise. As for the two visible ones, they are the Nile and the Furat.'" The hadith continues.
فذكر حديث الإسراء والمعراج، وجاء فيه: ورفعت لي سدرة المنتهى، فإذا نبقها كأنه قلال هجر، وورقها كأنه آذان الفيول، في أصلها أربعة أنهار: نهران باطنان، ونهران ظاهران، فسألت جبريل، فقال: أما الباطنان: ففي الجنة، وأما الظاهران: النيل والفرات الحديث.
Bukhari narrated it in the Beginning of Creation (3207), and Muslim in Faith (164), both of them through Saeed, who said, Qatada told us, who said, Anas bin Malik told us, from Malik bin Sasaa, and he mentioned it. The wording given here is Bukhari's, while in Muslim it reads, "The Prophet of Allah ﷺ told that he saw four rivers, two visible rivers and two hidden rivers issuing from their source. I said, 'O Jibreel, what are these rivers?' He said, 'As for the two hidden rivers, they are two rivers in Paradise, and as for the two visible ones, they are the Nil and the Euphrates.'" The hadith continues.
