The Prophet (peace and blessings of Allah be upon him) said: On the night of the Ascension, all the gardens of Paradise were presented to me. Among them were four rivers: a river of water, a river of milk, a river of wine, and a river of honey. Allah has said: In them are rivers of pure water, without any stench, and rivers of milk, the taste of which has not changed, and rivers of wine, a delight for those who drink it, and rivers of pure honey. For them there are fruits of every kind, and forgiveness from their Lord! Are these like those who will abide in the Fire of Hell, and will be given to drink boiling water that will tear their insides apart? (Muhammad: 15). I said: "O Gabriel! Where did these rivers come from and where do they go?" He said: “They are going to the Pool of Kauthar, but I do not know where they come from. Ask God to inform you or show you.” I also asked God; at that moment an angel came and greeted me and said: “O Muhammad (peace be upon him and his family)! Close your eyes.” I also closed my eyes; then he said: “Open your eyes.” I also opened them and saw myself next to a tree and saw a dome of shining pearls with a door of green ruby ​​and a lock of red gold. If all the humans and jinn in the world were to stand on that dome, they would be like a bird sitting on a mountain or an almond falling into the sea; and I saw these four rivers flowing from under this dome. When I wanted to return, the same angel said to me: “Why don’t you enter the dome?” I said, “How can I enter when there is a lock on the door?” The angel said, “Open the lock!” I said, “How can I open it when I do not have a key?” He said, “The key is in your hands.” I said, “Where is it?” He said, “The key is in the name of Allah, the Most Gracious, the Most Merciful.” So I approached and said, “In the name of Allah, the Most Gracious, the Most Merciful.” The lock turned and I entered the dome and I saw that these rivers were flowing from the four corners of the dome. When I wanted to leave the dome, an angel said to me, “Did you look and see?” I said, “Yes.” He said, “Look again.” When I looked, I saw that “In the name of Allah, the Most Gracious, the Most Merciful” was written on the four corners of the dome. And I saw a river of water flowing from the name of Allah, a river of milk flowing from the name of Allah, a river of wine flowing from the name of the Most Gracious, and a river of honey flowing from the name of the Most Merciful. I knew that the source of these four rivers was from the name of Allah. [At that time] Allah said: “O Muhammad! Whoever from your nation calls upon Me by these names with a pure intention and says in the name of Allah, the Most Gracious, the Most Merciful, I will give him drink from these four rivers.” God will give the people of Paradise water to drink on Saturday, and honey on Sunday, and milk on Monday, and wine on Tuesday. When they drink, they will become intoxicated. When they become intoxicated, they will fly for a thousand years until they reach a high mountain of fragrant musk, from under which flows the spring of Salsabil (a spring in Paradise), and they will drink from that spring. This will be on Wednesday. Then they will fly for another thousand years until they reach a palace made of agate stone, in which are placed high, beautiful thrones and goblets, as in the verse: In it are high, beautiful thrones, and goblets [of pure wine] are placed. (Ghashiyyah/1413) It has been mentioned, then each of them will sit on a throne and ginger wine will descend on them and they will drink from it, and this will be on Thursday. Then a white cloud made of saffron will rain on them for two thousand years, a thousand years of ornaments and a thousand years of gems will rain on them, and on each gem will hang a beautiful woman; then they will fly for another thousand years until they finally reach the true position [referring to the verse: In the position of truth with God, the Sovereign, the Mighty. (Qamar/55)], and this will be on Friday, and they will sit on the table of eternity and drink pure, untouched, sealed wine with a seal of musk on it [referring to the verses: They will be drunk from pure, untouched, sealed wine. The seal on it is of musk; And those who desire it should compete with one another for it. (Mutaffafeen/2625)] It will descend upon them and they will drink from it. The Messenger of God (peace and blessings of God be upon him and his family) said: “These are the ones who do righteous deeds and avoid sins.”
