حَدَّثَنَا عَبَّاسٌ الْعَنْبَرِيُّ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا شَرِيكٌ، عَنْ مُحَمَّدِ بْنِ جُحَادَةَ، عَنْ عَطَاءٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " فِي الْجَنَّةِ مِائَةُ دَرَجَةٍ مَا بَيْنَ كُلِّ دَرَجَتَيْنِ مِائَةُ عَامٍ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
Unreviewed translation. All hadiths in this collection are available in five languages. Titles and introductions may remain in Arabic.
Abu Hurairah reported that the Messenger of Allah said, ‘In Paradise are one hundred levels, with a distance of one hundred years between each two levels.’ Abu Isa graded this hadith hasan sahih.
Notes and open questions — unreviewed
The Arabic gives the distance between each pair of levels as a hundred years; it does not specify a unit of travel.
