وَ رَوَى حَفْصُ بْنُ اَلْبَخْتَرِيُّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: «إِنَّ جَبْرَئِيلَ عَلَيْهِ اَلسَّلاَمُ كَرَى بِرِجْلِهِ خَمْسَةَ أَنْهَارٍ وَ لِسَانُ اَلْمَاءِ يَتْبَعُهُ، اَلْفُرَاتَ وَ دِجْلَةَ وَ نِيلَ مِصْرَ وَ مِهْرَانَ وَ نَهَرَ بَلْخٍ فَمَا سَقَتْ أَوْ سُقِيَ مِنْهَا فَلِلْإِمَامِ وَ اَلْبَحْرُ اَلْمُطِيفُ بِالدُّنْيَا».
Hafs ibn al-Bakhtari narrated from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq عليه السلام who said: "Archangel Jibril عليه السلام struck the earth with his foot, creating five rivers, and the flow of water followed him: the Euphrates, the Tigris, the Nile of Egypt, the Mehran, and the river of Balkh. Whatever is irrigated by them or watered from them belongs to the Imam. This includes the encompassing ocean of the world."
