It was narrated that Abu Hurairah said:

“We used to narrate from the Messenger of Allah (ﷺ) and mention truffles, and they said: ‘(It is) the smallpox of the earth.’ When the Messenger of Allah (ﷺ) was told of what they were saying: he said: ‘Truffles are a type of manna, and the Ajwah are from Paradise, and they are a healing from poison.’”

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا أَبُو عَبْدِ الصَّمَدِ، حَدَّثَنَا مَطَرٌ الْوَرَّاقُ، عَنْ شَهْرِ بْنِ حَوْشَبٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كُنَّا نَتَحَدَّثُ عِنْدَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَذَكَرْنَا الْكَمْأَةَ فَقَالُوا هِيَ جُدَرِيُّ الأَرْضِ ‏.‏ فَنُمِيَ الْحَدِيثُ إِلَى رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالَ ‏

‏ الْكَمْأَةُ مِنَ الْمَنِّ وَالْعَجْوَةُ مِنَ الْجَنَّةِ وَهِيَ شِفَاءٌ مِنَ السَّمِّ ‏
