It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both), he says: Two men came to the Noble Prophet (peace and blessings be upon him), both had a similar need. When one of them spoke, the Prophet (peace and blessings be upon him) noticed an unpleasant odor from his mouth and asked him: "Do you not use the miswak?" He replied: "Yes, I certainly do, but the real matter is that I have not eaten food for three days." Then the Prophet (peace and blessings be upon him) instructed a man, so he gave him a place and fulfilled his need.
