Tafseer Abu-al-A'la Maududi

Page 356 English Traditional

*77) These words clearly state that thejudgement of the Prophet is the judgement of Allah and the Command of the Prophet is the Command of Allah. Therefore, the invitation to obey the Prophet is an invitation to obey both Allah and His Prophet. (Also see An-Nisa: 59-61, and the E.N.'s thereof).
*78) This dces not only apply to the cases which came up before the Holy Prophet for a decision in his lifetime, but this continues valid even today. Thus, a summon from the court of a judge in an Islamic government, who judges a case in accordance with the Book of Allah and the Sunnah of His Prophet, is actually a summon from the Court of Allah and His Prophet and the one who repudiates the judge indeed repudiates both Allah and His Prophet. This thing has been explained in a tradition related by Hasan Basri thus: "Whosoever is summoned to appear before a judge from among the judges of the Muslims but fails to appear before him, he is a transgressor and forfeits his rights." (Al-Jassas, Ahkam-ul-Qur'an, Vol. III, p. 405). In other words, such a person not only renders himself punishable but also guilty and liable to be proceeded against.
