The Book of Occultation — al-Ṭūsī · Hadith 27 (#Ḥadīth #21)
Chapter 3 | First Principle: Necessity of Imamate
فإن قيل:لا يخلو وجود رئيس مطاع منبسط اليد من أن يجب على الله جميع ذلك أو يجب علينا جميعه أو يجب على الله إيجاده وعلينا بسط يده.
If it is said: Given the existence of a leader, who is obeyed and runs the affairs of the society is necessary, either it is all the work of Allah to offer, or it is for Allah to create him and for us to empower him with the administration of the society, or it is required of us both to create and empower him.
