Sunan Ibn Majah 184
It was narrated that Jabor bin 'Abdullah said:
"The Messenger of Allah said: 'While the people of Paradise are enjoying their blessings, a light will shine upon them, and they will raise their heads, and they will see their Lord looking upon them from above. He will say: "Peace be upon you, O people of Paradise." This is what Allah says in the Verse: "Salam (peace be upon you) - a Word from the Lord (Allah), The Most Merciful." He will look at them, and they will look at Him, and they will not pay any attention to the delights (of Paradise) so long as they look at Him, until He will screen Himself from them. But His light and blessing will remain with them in their bodies.'"
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْمَلِكِ بْنِ أَبِي الشَّوَارِبِ، حَدَّثَنَا أَبُو عَاصِمٍ الْعَبَّادَانِيُّ، حَدَّثَنَا الْفَضْلُ الرَّقَاشِيُّ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ بَيْنَا أَهْلُ الْجَنَّةِ فِي نَعِيمِهِمْ إِذْ سَطَعَ لَهُمْ نُورٌ فَرَفَعُوا رُءُوسَهُمْ فَإِذَا الرَّبُّ قَدْ أَشْرَفَ عَلَيْهِمْ مِنْ فَوْقِهِمْ فَقَالَ السَّلاَمُ عَلَيْكُمْ يَا أَهْلَ الْجَنَّةِ ‏.‏ قَالَ وَذَلِكَ قَوْلُ اللَّهِ ‏{سَلاَمٌ قَوْلاً مِنْ رَبٍّ رَحِيمٍ}‏ قَالَ فَيَنْظُرُ إِلَيْهِمْ وَيَنْظُرُونَ إِلَيْهِ فَلاَ يَلْتَفِتُونَ إِلَى شَىْءٍ مِنَ النَّعِيمِ مَا دَامُوا يَنْظُرُونَ إِلَيْهِ حَتَّى يَحْتَجِبَ عَنْهُمْ وَيَبْقَى نُورُهُ وَبَرَكَتُهُ عَلَيْهِمْ فِي دِيَارِهِمْ ‏"‏ ‏.‏
