“Water was sprinkled on the grave of the Noble Prophet (peace and blessings of Allah be upon him). Bilal (may Allah be pleased with him) sprinkled water from a waterskin on the grave of the Prophet (peace and blessings of Allah be upon him). He began sprinkling from the head side and continued sprinkling water up to the foot side.”

"The Messenger of Allah (peace and blessings be upon him) sprinkled water on the grave of his son Ibrahim and placed pebbles on it."
