The Religion
الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلَامَ دِينًا ۚ {3}
Today I Perfected your Religion for you and Completed My Favour upon you, and am Pleased with ‘الْإِسْلَامَ دِينًا ’ Al-Islam as a Religion for you.
عن ابن أذينة قال: سمعت زرارة، عن أبي جعفر (عليه السلام): «أن الفريضة كانت تنزل، ثم تنزل الفريضة الاخرى، فكانت الولاية آخر الفرائض، فأنزل الله: الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَ أَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَ رَضِيتُ لَكُمُ الْإِسْلامَ دِيناً- فقال أبو جعفر (عليه السلام)- يقول الله: لا انزل عليكم بعد هذه الفريضة فريضة
From Ibn Azina who said, ‘I heard Zurara,
From Abu Ja’far-asws (saying): ‘The Obligation used to be Revealed, then another Obligation was Revealed. But, the Wilayah is the last of the Obligations, so Allah-azwj Revealed: Today I Perfected your Religion for you and Completed My Favour upon you, and am Pleased with Al Islam as a Religion for you [5:3]’. Abu Ja’far-asws said: ‘Allah-azwj is Saying: “I-azwj will not be Revealing upon you an Obligation after this Obligation (of Wilayah)’.[1]
محمد بن يعقوب: عن أبي محمد القاسم بن العلاء (رحمه الله)، رفعه، عن عبد العزيز بن مسلم، قال: كنا مع الرضا (عليه السلام) بمرو، فاجتمعنا في الجامع يوم الجمعة في بدء مقدمنا، فأداروا أمر الإمامة، و كثرة اختلاف الناس فيها، فدخلت على سيدي (عليه السلام)، فأعلمته في خوض الناس فيه، فتبسم (عليه السلام)، ثم قال: «يا عبد العزيز، جهل القوم، و خدعوا عن أديانهم
Muhammad Bin Yaqoub, from Abu Muhammad Al-Qasim Bin Al-A’la, raising it, from Abdul Aziz Bin Muslim who said,
‘I was with Al-Reza-asws as Merv, and we had gathered in the Mosque on Friday during the beginning of our arrival. So they were narrating the matter of the Imamate, and there was a lot of differing by the people with regards to it. So I went over to my Master-asws and informed him-asws of the quarrelling of the people regarding it. He-asws smiled at me, then said: ‘O Abdul Aziz! The people are ignorant and have been deceived about their religions.
إن الله عز و جل لم يقبض نبيه (صلى الله عليه و آله) حتى أكمل له الدين، و أنزل عليه القرآن فيه تبيان كل شيء، بين فيه الحلال و الحرام، و الحدود و الأحكام، و جميع ما يحتاج إليه الناس كملا
Allah-azwj Mighty and Majestic did not Cause His-azwj Prophet-saww to pass away until Completing the Religion for him-saww, and Revealed the Quran unto him-saww in which is the explanation of everything, regarding the Permissibles, and the Prohibitions, and the Legal punishment, and the Ordinances, and the entirety of what the people would be needy to from him-saww in totality.
و قال عز و جل: ما فَرَّطْنا فِي الْكِتابِ مِنْ شَيْءٍ و أنزل فيه ما أنزل في حجة الوداع- و هي آخر عمره (صلى الله عليه و آله)-: الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَ أَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَ رَضِيتُ لَكُمُ الْإِسْلامَ دِيناً، و أمر الإمامة من تمام الدين،
And the Mighty and Majestic Said: We did not neglect in the Book of anything [6:38];and Revealed in it what He-azwj Revealed during the Farewell Pilgrimage – and it was at the end of his-saww lifetime: Today I Perfected your Religion for you and Completed My Favour upon you, and am Pleased with Al Islam as a Religion for you [5:3]. And the matter of Imamate is from the Completion of the Religion.
و لم يمض رسول الله (صلى الله عليه و آله) حتى بين لامته معالم دينهم، و أوضح لهم سبيلهم، و تركهم على قصد سبيل الحق، و أقام لهم عليا (عليه السلام) علما و إماما، و ما ترك شيئا تحتاج إليه الامة إلا بينه، فمن زعم أن الله عز و جل لم يكمل دينه فقد رد كتاب الله، و من رد كتاب الله فهو كافر به
And Rasool-Allah-saww did not leave (this world) until he-saww had explained to his-saww community, then the matters of their Religion, and clarified for them their way, and left them facing the Way of the Truth. And he-saww nominated for them Ali-asws as a flag and an Imam-asws. And he-saww did not leave anything out which the community would need from him-saww except that he-saww explained it. So the one who claims that Allah-azwj Mighty and Majestic did not Complete His-azwj Religion, so he has rejected the Book of Allah-azwj, and the one who rejects the Book of Allah-azwj so he is a Kafir with it.[2]
