Narrated Aisha (may Allah be pleased with her): The Prophet (peace and blessings of Allah be upon him) spent a night awake (in vigilance). After arriving in Madinah, he (peace be upon him) said, "Would that a righteous man from among my companions would guard me tonight!" (While these words were being spoken,) we heard the clanging of weapons. The Prophet (peace be upon him) asked, "Who is it?" (The person coming) said, "It is Sa'd bin Abi Waqqas. I have come to guard you." Then the Prophet (peace be upon him) was pleased, prayed for him, and went to sleep.

Hazrat Ali (may Allah be pleased with him) narrated that after Sa’d bin Abi Waqqas (may Allah be pleased with him), I did not hear the Prophet Muhammad (peace and blessings be upon him) say about anyone that he would sacrifice himself for them. I heard that the Prophet (peace and blessings be upon him) was saying,“Shoot arrows (O Sa’d, may Allah be pleased with him), may my parents be sacrificed for you.”

Hazrat Sa'd bin Abi Waqqas (may Allah be pleased with him) narrated that on the occasion of the Battle of Uhud, the Prophet Muhammad (peace and blessings be upon him) combined his parents for me (and said: "May my mother and father be sacrificed for you.").

Hazrat Abu Uthman (may Allah be pleased with him) narrated that in those battles in which the Messenger of Allah (peace and blessings of Allah be upon him) himself participated, there were some days (such as in the Battle of Uhud) when, except for Talha (may Allah be pleased with him) and Sa’d (may Allah be pleased with him), no one else remained with the Prophet (peace and blessings of Allah be upon him). (The narrator says) This statement was made by both Hazrat Talha and Hazrat Sa’d (may Allah be pleased with them) themselves.

Jabir (may Allah be pleased with him) narrated that the Prophet (peace and blessings be upon him) said on the day of the Battle of the Trench: "Who will bring me news of the enemy's army?" (By enemy here is meant Banu Qurayza.) Zubair (may Allah be pleased with him) said, "I will." The Prophet (peace and blessings be upon him) asked again: "Who will bring me news of the enemy's army?" This time also Zubair (may Allah be pleased with him) said, "I will." Upon this, the Prophet (peace and blessings be upon him) said: "Every prophet has disciples (true helpers), and my disciple is Zubair."

Narrated Abdullah bin Zubair (may Allah be pleased with him): On the occasion of the Battle of Ahzab, I and Umar bin Abi Salamah (may Allah be pleased with him) were left among the women (because both of us were children). Suddenly, I saw that Zubair (may Allah be pleased with him) (your father) was riding his horse, going towards Banu Qurayza (a tribe of Jews), and this happened two or three times. Then when he returned from there, I said, "Father! I saw you going and coming several times." He said, "Son! Did you really see that?" I replied, "Yes." He said, "The Messenger of Allah (peace and blessings of Allah be upon him) had said, 'Who will go to Banu Qurayza and bring me news of their movements?' So I went there, and when I returned with the information, the Messenger of Allah (peace and blessings of Allah be upon him), out of great happiness, mentioned both his parents together and said, 'May my father and mother be sacrificed for you.'"

Hazrat Anas bin Malik (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: In every nation there are trustworthy people, and the trustworthy one of this nation is Abu Ubaidah bin Jarrah.

Hazrat Hudhaifah (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said to the people of Najran: "I will send to you a trustworthy person who is truly trustworthy." Upon hearing this, all the companions (may Allah be pleased with them) became eager, but the Prophet (peace and blessings be upon him) sent Hazrat Abu Ubaidah (may Allah be pleased with him).

Hazrat Abu Hurairah Dosi (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings of Allah be upon him) set out during a part of the day. Neither did he (peace be upon him) speak to me, nor did I speak to him. In this manner, he reached the market of Banu Qaynuqa, then (returned and) sat in the courtyard of Fatimah’s (may Allah be pleased with her) house and said:“Where is the child, where is the child?”Fatimah (may Allah be pleased with her) could not immediately come to your (peace be upon him) service due to some engagement. I thought, perhaps she is dressing Hasan (may Allah be pleased with him) or bathing him. After a short while, Hasan (may Allah be pleased with him) came running; he (peace be upon him) embraced him and kissed him. Then he said:“O Allah! Love him and love the one who loves him.”

Narrated Al-Bara' (may Allah be pleased with him): I saw the Messenger of Allah (peace and blessings of Allah be upon him) while Al-Hasan (may Allah be pleased with him) was on his blessed shoulder, and he (the Prophet) was saying: "O Allah! I love him, so You also love him."
