Abd al-Rahman bin al-Harith bin Ubaydah transmits the statement of his grandfather: On the day of the Battle of Uhud, the eye of Sayyiduna Abu Dharr (may Allah be pleased with him) was injured. The Prophet (peace and blessings be upon him) put his saliva into it, and it became the healthier of his two eyes.
Abu Ya'la recorded it. Its chain contains Abd al-Aziz bin Imran, and he is da'if (weak).
