It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade me from three things. Now I do not know whether this prohibition was specifically for me or general for everyone. The Prophet (peace and blessings be upon him) forbade me from (wearing) silk, from (using) a red saddle-cloth, and from reciting the Qur'an during bowing (ruku‘).
