al-Fārisī:

“You Arabs have a claim upon us: that we should neither lead you in your prayers nor marry your women.”

Those who hold the first view say that Salmān said this only out of deference to the Arabs over the Persians, just as a man might say to someone of nobler standing, “You have such-and-such a claim upon me.” Salmān’s statement is not a religious ruling that everyone must follow as they must follow the rulings of Allah and His Messenger. Nevertheless, any Persian who follows Salmān’s example has a good model in him, for Salmān was foremost among the Persians in embracing Islam.

Likewise, taking lineage into account regarding the People of the Book is not a position held by any of the Companions, nor is it the position of the majority of scholars, such as Mālik, Abū Hanīfah, Ahmad ibn Hanbal, and his early followers. Some of his followers, however, reported two opinions from him, and some chose to take lineage into account, agreeing with al-Shāfi‘ī. Al-Shāfi‘ī took this view from ‘Atā’. A detailed discussion of this belongs elsewhere.

The point here is that the Prophet, may Allah bless him and grant him peace, based his rulings only on attributes relevant to what Allah loves and what He hates. He commanded what Allah loves and called people to it as far as possible, and he forbade what Allah hates and cut off its causes as far as possible. He did not single out the Arabs for any particular kind of religious ruling, since his call was addressed to all humanity. The Quran, however, was revealed in their language—indeed, in the language of Quraysh—as is reliably reported
