The jurists of the Shāfiʿī and Ḥanbalī schools cite this narration to show that noble lineage justifies precedence in leading the congregational prayer.
A related report is transmitted by Muḥammad ibn Abī ʿUmar al-ʿAdanī. He said: Saʿīd ibn ʿUbayd told us, ʿAlī ibn Rabīʿah informed us, from Rabīʿ ibn Faḍlah, that he once set out with twelve riders. All of them—aside from himself—had accompanied Muhammad, peace and blessings be upon him, and among them was Salmān al-Fārisī. While they were on a journey the time for prayer arrived. Each man tried to push the other forward to lead, until one of them finally stepped up and led a four-rakʿah prayer.
When the prayer was over, Salmān repeated several times, “What is this? What is this? Half of the four-unit prayer—” Marwān explained, meaning two of the four—“we are the ones most in need of the concession of shortening.”
The others said, “Lead us in prayer, Abū ʿAbd Allāh; you are the most entitled among us.” He replied, “No. You, the sons of Ishmael, are the imams, and we are the ministers.”
There are other reports on this issue besides the ones I have mentioned; some warrant scrutiny, and some are fabricated. Moreover, when ʿUmar ibn al-Khaṭṭāb—may Allah be pleased with him—established the register of stipends, he listed people in order of their lineage, beginning with those closest, then the next closest, to the Messenger of Allah, peace and blessings be upon him. Once he had completed the Arabs, he then listed the non-Arabs. That remained the arrangement of the register in the time of the Rightly Guided Caliphs, the Umayyad caliphs, and the ʿAbbāsid caliphs, until matters later changed.
