(31) باب فِي الْكَحْلِ عِنْدَ النَّوْمِ لِلصَّائِمِ
Narrated Ma'bad b. Hudhah:
The Prophet (ﷺ) commanded to apply collyrium mixed with musk at the time of sleep. He said: A man who is fasting should abstain from it.Abu Dawud said: Yahya b. Ma'in said to me: This tradition about the use of collyrium is munkar (i.e. contradicts the sound traditions on the subject).
