Complete Tafseer from Agha Mahdi Pooya regarding Surah An-Nisaa’ – Ayat 59
"Obey Allah and obey the messenger and the ulil amr (those vested with authority through His messenger)."
The command to obey is infinite-total obedience in all material, religious and spiritual matters, therefore, as this verse clearly signifies, the ulil amr must also be as just, wise and merciful as Allah and the Holy Prophet are, and he who - administers the affairs of mankind should be the khalifatullah (vicegerent of Allah) and the waliallah (representative of Allah whom He chooses after equipping him with His wisdom). Please refer to the commentary of al-Baqarah, 2:30 to 39 and 124; and al-Ma’idah, 5:55 and 56 and 3 and 67 with reference to the event at Ghadir Khumm; and al-Rad, 13: 43; and Hud, 11: 17.
A careful study of the above references discloses that Ali, and after him, the remaining eleven Imams, in the progeny of the Holy Prophet, Ali and Fatimah, are the true successors of the Holy Prophet who have been referred to as ulil amr in this verse. So the Shias obey and follow the Holy Prophet and the twelve Imams.
It is irrational and senseless to accept any ruler as ulil amr, otherwise men like Yazid bin Muawiya will have to be included in the category of ulil amr; and no sane person would say that Allah has enjoined to obey men like Yazid (prototypes of whom were and are many and in abundance since the departure of the Holy Prophet till today) just as one obeys Allah and the Holy Prophet.
From the event of ashira (feast of the near relatives to carry out the divine command of "warn your tribe of near relatives") to the day at Ghadir Khumm, the Holy Prophet repeatedly announced the successorship of Ali, therefore, the first step a true Muslim must take to obey the messenger of Allah is to obey and follow Ali ibn abi Talib. Also refer to the "Right Path" and "Peshawar Nights"1, published by the Peermohammed Ebrahim Trust or Zahra Publications, because the issue of ulil amr and wali has been discussed in depth in these books with authentic references from the well-known books of Tafseer (exegesis) and hadith (traditions) written by the Muslim scholars.
Today the Muslim ummah (from Indonesia to Morocco) is in a quandary, because the theoreticians who directly or indirectly served the interests of the despotic rulers, have presented "the obedience to ruler" (even if he is an usurper, a rogue or a ruffian) as a fundamental of religion (known as the theory of ghlu and ghalba-violence and conquest) by misinterpreting this verse. Such theoreticians are their Imams. There is no way leading to emancipation from terror and exploitation if this theory is not rightly rejected once and for all. It is not possible unless the sincere Muslims submit to the teachings of the Ahl ul Bayt.
