باب مَا بَيْنَ الْقَبْرِ وَالْمِنْبَرِ رَوْضَةٌ مِنْ رِيَاضِ الْجَنَّةِ ‏‏
Sahih Muslim 1390 a

AbduUah b. Zaid al-Mazini (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:

That which is between my house" and my pulpit is a garden from the gardens of Paradise.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكِ بْنِ أَنَسٍ، فِيمَا قُرِئَ عَلَيْهِ عَنْ عَبْدِ اللَّهِ بْنِ أَبِي، بَكْرٍ عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَبْدِ اللَّهِ بْنِ زَيْدٍ الْمَازِنِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَا بَيْنَ بَيْتِي وَمِنْبَرِي رَوْضَةٌ مِنْ رِيَاضِ الْجَنَّةِ ‏"‏ ‏.‏
