the Messenger of Allah ﷺ said: "al-ajwah ˹date˺ is from Paradise and it contains a cure for poison. Truffles are a form of manna, and its liquid is a cure for the eye."
قَالَ رَسُولُ اللَّهِ ﷺ الْعَجْوَةُ مِنَ الْجَنَّةِ وَفِيهَا شِفَاءٌ مِنَ السُّمِّ وَالْكَمْأَةُ مِنَ الْمَنِّ وَمَاؤُهَا شِفَاءٌ لِلْعَيْنِ
