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
He said the Prophet (sallallahu alayhi wa sallam) used to apply antimony three times in each eye before going to sleep, and reported him as saying, “The best medicines you apply are those sipped at the corners of the mouth, those snuffed up the nose, cupping, purgatives; the best thing you apply to your eyes is antimony, for it clears the sight and makes the hair grow; and the best days for cupping are the seventeenth, nineteenth and twenty-first.”
When God’s messenger was taken up to visit heaven every company of angels he passed said, “Keep up the practice of cupping.”
