Sayyiduna Aws bin Aws (may Allah be pleased with him) said: I stayed with the Prophet (peace and blessings be upon him) for half a month. I saw him (peace and blessings be upon him) praying while he (peace and blessings be upon him) was wearing sandals with two straps, and I saw him (peace and blessings be upon him) spit to his right and his left.
