It is narrated from Hazrat Anas (may Allah be pleased with him) that sometimes the Prophet (peace and blessings be upon him) would be descending from the pulpit on Friday, and if a person wanted to speak to the Prophet (peace and blessings be upon him) regarding some matter of his, the Prophet (peace and blessings be upon him) would speak to him.
