She (A'isha) reported: We were in this state that we heard the clanging noise of arms. lie (the Holy Prophet) said: Who is it? He said: This is Sa'd b. Abi Waqqas. Allah's Messenger (PBUH) said to him: What brings you here? Thereupon he said: I harboured fear (lest any harm should come to) Allah's Messenger (PBUH), so I came to serve as your sentinel.
