The Prophet (ﷺ) added:
وَقَالَ إِبْرَاهِيمُ بْنُ طَهْمَانَ عَنْ شُعْبَةَ ، عَنْ قَتَادَةَ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " رُفِعْتُ إِلَى السِّدْرَةِ فَإِذَا أَرْبَعَةُ أَنْهَارٍ، نَهَرَانِ ظَاهِرَانِ، وَنَهَرَانِ بَاطِنَانِ، فَأَمَّا الظَّاهِرَانِ النِّيلُ وَالْفُرَاتُ، وَأَمَّا الْبَاطِنَانِ فَنَهَرَانِ فِي الْجَنَّةِ فَأُتِيتُ بِثَلاَثَةِ أَقْدَاحٍ، قَدَحٌ فِيهِ لَبَنٌ، وَقَدَحٌ فِيهِ عَسَلٌ، وَقَدَحٌ فِيهِ خَمْرٌ، فَأَخَذْتُ الَّذِي فِيهِ اللَّبَنُ فَشَرِبْتُ فَقِيلَ لِي أَصَبْتَ الْفِطْرَةَ أَنْتَ وَأُمَّتُكَ ". قَالَ هِشَامٌ وَسَعِيدٌ وَهَمَّامٌ عَنْ قَتَادَةَ عَنْ أَنَسِ بْنِ مَالِكٍ عَنْ مَالِكِ بْنِ صَعْصَعَةَ عَنِ النَّبِيِّ صلى الله عليه وسلم فِي الأَنْهَارِ نَحْوَهُ، وَلَمْ يَذْكُرُوا ثَلاَثَةَ أَقْدَاحٍ .
I was raised to the Lote Tree and saw four rivers, two of which were coming out and two going in. Those which were coming out were the Nile and the Euphrates, and those which were going in were two rivers in paradise. Then I was given three bowls, one containing milk, and another containing honey, and a third containing wine. I took the bowl containing milk and drank it. It was said to me, "You and your followers will be on the right path (of Islam)."
