It is narrated from the narrator of the previous Hadith from Musa ibn al-Qasim from Safwan from Zurarah who has said the following: “Abu ‘Abd Allah , has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, applied eye powder before going to sleep-four times in the right and three in the left.’”
