This hadith has transmitted on the authority of Abu Sa'id that Messenger of Allah ﷺ asked Ibn Sa'id about the earth of Paradise. Thereupon he said: Abu'l-Qasim, It is like a fine white musk, whereupon he (the Holy Prophet) said: 'You have told the the truth.
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا بِشْرٌ، - يَعْنِي ابْنَ مُفَضَّلٍ - عَنْ أَبِي مَسْلَمَةَ،
عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لاِبْنِ صَائِدٍ "
مَا تُرْبَةُ الْجَنَّةِ " . قَالَ دَرْمَكَةٌ بَيْضَاءُ مِسْكٌ يَا أَبَا الْقَاسِمِ . قَالَ " صَدَقْتَ " .
