Sayyiduna Uqbah bin Amir (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) saw Subay'ah al-Aslamiyyah eating with her left hand and said: "What is the matter with her that she is eating with her left hand? Do I find her to be mischievous?" She said: "O Messenger of Allah! There is a sore on my right hand." He (peace and blessings be upon him) said: "Even so."
