Abu Sa'id al-Khudri (may Allah be pleased with him) relates that Sayyiduna Zayd bin Thabit (may Allah be pleased with him) told him: Once the Messenger of Allah (peace and blessings be upon him) was in a garden belonging to Banu al-Najjar, riding his mule (peace and blessings be upon him), and we were with him (peace and blessings be upon him). He (peace and blessings be upon him) said: "Seek refuge with Allah from the punishment of the grave; seek refuge with Allah from the punishment of the Fire." We said: We seek refuge with Allah from the punishment of the grave; we seek refuge with Allah from the punishment of the Fire. He (peace and blessings be upon him) said: "Seek refuge with Allah from trials, the open and the hidden." We said: We seek refuge with Allah from trials, the open and the hidden. He (peace and blessings be upon him) said: "Seek refuge with Allah from the trial of the Dajjal." The people said: We seek refuge with Allah from the trial of the Dajjal.

Abu Sa'id al-Khudri (may Allah be pleased with him) relates that when the Prophet (peace and blessings be upon him) passed away, the orators of the Ansar stood up and said: O assembly of the Muhajirun! Whenever the Messenger of Allah (peace and blessings be upon him) sent one of you on a task, he would pair him with a man from among us. So our view is that this matter too should be taken on by two men, one from you and one from us. At that, Zayd bin Thabit (may Allah be pleased with him) stood up and said: The Messenger of Allah (peace and blessings be upon him) was from the Muhajirun, and we were the Ansar (helpers) of the Messenger of Allah (peace and blessings be upon him); so we are the helpers of whoever takes his (peace and blessings be upon him) place. Thereupon Abu Bakr (may Allah be pleased with him) said: "O assembly of the Ansar! May Allah reward you with the best reward as a tribe, and keep your speaker firm. By Allah! Had anything other than this been said, we would not have made peace with you."
