Mishkat al-Masabih, 2686

‘Uthman told on the authority of God’s messenger that when a man has a complaint in his eyes while he is in the sacred state, he should apply aloes to them. Muslim transmitted it.

وَعَن عُثْمَان حَدَّثَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الرَّجُلِ إِذَا اشْتَكَى عَيْنَيْهِ وَهُوَ محرمٌ ضمدهما بِالصبرِ. رَوَاهُ مُسلم
