Narrated Anas:

Allah's Apostle went to (the house of) his slave tailor, and he was offered (a dish of) gourd of which he started eating. I have loved to eat gourd since I saw Allah's Apostle eating it.

حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ، حَدَّثَنَا أَزْهَرُ بْنُ سَعْدٍ، عَنِ ابْنِ عَوْنٍ، عَنْ ثُمَامَةَ بْنِ أَنَسٍ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ أَتَى مَوْلًى لَهُ خَيَّاطًا، فَأُتِيَ بِدُبَّاءٍ، فَجَعَلَ يَأْكُلُهُ، فَلَمْ أَزَلْ أُحِبُّهُ مُنْذُ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَأْكُلُهُ.
