Sayyiduna Aws bin Aws al-Thaqafi (may Allah be pleased with him) said: We stayed with the Prophet (peace and blessings be upon him) for half a month. I saw him (peace and blessings be upon him) turn away (after the prayer) from his right side, and I also saw him (peace and blessings be upon him) turn away from his left side, and I saw his (peace and blessings be upon him) sandals; they had two straps.
