Hadith 5654

Jabir told that when a man asked God's messenger whether the inhabitants of paradise would sleep, he replied, "Sleep is the brother of death, and the inhabitants of paradise do not die." Baihaqi transmitted it in Shu'ab al-iman.

وَعَنْ جَابِرٍ قَالَ: سَأَلَ رَجُلٌ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَيَنَامُ أَهْلُ الْجَنَّةِ؟ قَالَ: «النَّوْمُ أَخُو الْمَوْتِ وَلَا يَمُوتُ أَهْلُ الجنةِ» . رواهُ البيهقيُّ فِي «شعب الْإِيمَان»
