حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ قَالَ: حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، عَنْ عَبْدِ اللَّهِ بْنِ عُثْمَانَ بْنِ خُثَيْمٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ خَيْرَ أَكْحَالِكُمُ الْإِثْمِدُ، يَجْلُو الْبَصَرَ، وَيُنْبِتُ الشَّعْرَ»
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both), he says that the Messenger of Allah (peace and blessings be upon him) said: "The best kohl among all your kohls is Ithmid; it brightens the eyesight and grows (the eyelashes') hair."
