This hadith has been transmitted on the authority of Abu Bakr b. Abu Musa b. Qais who, on the authority of his father, reported the Apostle to have said that there would be a tent made of a pearl whose height towards the sky would be sixty miles. In each corner, there would be a family of the believer, out of sight for the others.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا هَمَّامٌ، عَنْ أَبِي، عِمْرَانَ الْجَوْنِيِّ عَنْ أَبِي بَكْرِ بْنِ أَبِي مُوسَى بْنِ قَيْسٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ الْخَيْمَةُ دُرَّةٌ طُولُهَا فِي السَّمَاءِ سِتُّونَ مِيلاً فِي كُلِّ زَاوِيَةٍ مِنْهَا أَهْلٌ لِلْمُؤْمِنِ لاَ يَرَاهُمُ الآخَرُونَ ‏" ‏ ‏.‏
