Imam Bukhari : 6493حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الْجُعْفِيُّ حَدَّثَنَا حَرَمِيُّ بْنُ عُمَارَةَ حَدَّثَنَا قُرَّةُ بْنُ خَالِدٍ عَنْ مُحَمَّدِ بْنِ سِيرِينَ قَالَ قَالَ قَيْسُ بْنُ عُبَادٍكُنْتُ فِي حَلْقَةٍ فِيهَا سَعْدُ بْنُ مَالِكٍ وَابْنُ عُمَرَ فَمَرَّ عَبْدُ اللَّهِ بْنُ سَلَامٍ فَقَالُوا هَذَا رَجُلٌ مِنْ أَهْلِ الْجَنَّةِ فَقُلْتُ لَهُ إِنَّهُمْ قَالُوا كَذَا وَكَذَا قَالَ سُبْحَانَ اللَّهِ مَا كَانَ يَنْبَغِي لَهُمْ أَنْ يَقُولُوا مَا لَيْسَ لَهُمْ بِهِ عِلْمٌ إِنَّمَا رَأَيْتُ كَأَنَّمَا عَمُودٌ وُضِعَ فِي رَوْضَةٍ خَضْرَاءَ فَنُصِبَ فِيهَا وَفِي رَأْسِهَا عُرْوَةٌ وَفِي أَسْفَلِهَا مِنْصَفٌ وَالْمِنْصَفُ الْوَصِيفُ فَقِيلَ ارْقَهْ فَرَقِيتُهُ حَتَّى أَخَذْتُ بِالْعُرْوَةِ فَقَصَصْتُهَا عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَمُوتُ عَبْدُ اللَّهِ وَهُوَ آخِذٌ بِالْعُرْوَةِ الْوُثْقَى
Narrated to us [Abdullah bin Muhammad Al Ju'fi] narrated to us [Harami bin Umarah] narrated to us [Qurrah bin Khalid] from [Muhammad bin Sirin] said, [Qais bin Ubad] said, I was in a gathering with Sa'd bin Malik and Ibnu Umar, and Abdullah bin Salam passed by, and they said, 'This is a man from the people of Paradise.' I said to him, 'They said such and such.' He said, 'Glory be to Allah, they should not say what they have no knowledge of. I only saw in a dream that a pillar was placed in a green garden, and it was set up there, with a loop at its top and a servant at its base, and the servant was the helper. It was said, Climb it," so I climbed it until I took hold of the loop.' I narrated it to the Messenger of Allah, peace and blessings be upon him, and he said, 'Abdullah will die while holding the firmest handle.'"
