Sahih al-Bukhari 4639

Narrated Said Ibn Zaid:

The Prophet ﷺ said, "Al-Kam'a is like the Mann (sweet resin or gum) (in that it grows naturally without human care) and its water is a cure for the eye diseases."

حَدَّثَنَا مُسْلِمٌ، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الْمَلِكِ، عَنْ عَمْرِو بْنِ حُرَيْثٍ، عَنْ سَعِيدِ بْنِ زَيْدٍ، عَنِ النَّبِيِّ ﷺ قَالَ " الْكَمْأَةُ مِنَ الْمَنِّ وَمَاؤُهَا شِفَاءُ الْعَيْنِ ".
