It is narrated from Amir al-Mu'minin Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) forbade wearing Qassi (a type of silk cloth), wearing clothes dyed with Kusum, wearing a gold ring, and reciting the Qur'an during bowing (ruku‘).

`Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) saw me wearing two garments dyed with safflower and said, "These are the clothes of the disbelievers, do not wear them."
