وَعَنْهُ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَكْتَحِلُ قَبْلَ أَنْ يَنَامَ بِالْإِثْمِدِ ثَلَاثًا فِي كُلِّ عَيْنٍ قَالَ: وَقَالَ: «إِنَّ خَيْرَ مَا تَدَاوَيْتُمْ بِهِ اللَّدُودُ وَالسَّعُوطُ وَالْحِجَامَةُ وَالْمَشِيُّ وَخَيْرَ مَا اكْتَحَلْتُمْ بِهِ الْإِثْمِدُ فَإِنَّهُ يَجْلُو الْبَصَرَ وَيُنْبِتُ الشَّعْرَ وَإِنَّ خَيْرَ مَا تَحْتَجِمُونَ فِيهِ يَوْمُ سَبْعَ عَشْرَةَ وَيَوْمُ تِسْعَ عَشْرَةَ وَيَوْمُ إِحْدَى وَعِشْرِينَ» وَإِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حَيْثُ عُرِجَ بِهِ مَا مَرَّ عَلَى مَلَأٍ مِنَ الْمَلَائِكَةِ إِلَّا قَالُوا: عَلَيْكَ بِالْحِجَامَةِ. رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ
He reported: The Prophet ﷺ used to apply antimony before sleeping, three strokes in each eye. He also reported the Prophet ﷺ saying, “The best treatments are medicines administered at the side of the mouth, medicines sniffed through the nose, cupping, and purgatives. The best thing with which you treat the eyes is antimony, for it clears the sight and helps the eyelashes grow. The best days for cupping are the seventeenth, nineteenth, and twenty-first.” On the night the Messenger of Allah ﷺ was taken up, he passed no group of angels without their saying, “Keep up cupping.” Al-Tirmidhi transmitted it and said, “This is a good, rare hadith.”
