Sayyiduna Awf bin Malik al-Ashja'i (may Allah be pleased with him) said: I came to the Prophet (peace and blessings be upon him) during the expedition of Tabuk while he (peace and blessings be upon him) was seated in a tent made of leather. I sat in the courtyard of the tent and gave the greeting of peace, and he (peace and blessings be upon him) returned the greeting and said: "O Awf, come in." I said: All of me, or part of me? He (peace and blessings be upon him) said: "No, all of you." So I went in.
