I heard Messenger of Allah ﷺ as saying: Truffles are a kind of blessing and their juice is a medicine for the eyes. Shu'ba said: When Hakam narrated this hadith to me, I did not deem it as a Munkar hadith because of the narration of Abd al-Malik. (Using translation from Muslim 2049c)
عَنِ النَّبِيِّ ﷺ قَالَ شُعْبَةُ لَمَّا حَدَّثَنِي بِهِ الْحَكَمُ لَمْ أُنْكِرْهُ مِنْ حَدِيثِ عَبْدِ الْمَلِكِ
