رَبَّنَا وَابْعَثْ فِيهِمْ رَسُولًا مِنْهُمْ يَتْلُو...
Accept from us, surely thou art the hearing the knowing, Our Lord and make us both submissive to thee and (raise) from our offspring a nation submitting to thee and show our ways of devotion and turn to us (mercifully), surely thou art the oft returning (to mercy), the merciful. Our Lord and raise up in them an Apostle from among them who shall recite to them thy communications and teach them the book and the wisdom, and purify them, surely thou art the mighty, the wise.
(Surah Baqarah 2:127-129) When Allah accepted the supplication of Ibrahim and Ismail and appointed Imams from his progeny who will be obedient and from that nation and appointed a Prophet who will read the verses of Allah and teach the book and wisdom.
Make this city secure and save me and my sons from worshipping idols. My Lord! Surely they have led many men astray, then whoever follows me, he is surely of me, and whoever disobeys me, Thou surely art forgiving Merciful. (Surah Ibrahim 14:36) The Imam said that Imams and the nation can be only those from whom the Prophet has been raised and they will be from the progeny of Ibrahim.
…therefore make the hearts of some people yearn towards them… (Surah Ibrahim 14:37) Ibne Shahr Aashob has narrated from Imam Baqir (a.s.) that he said: The ‘best nation’ are Ahle Bayt of the Prophet and according to another tradition the Ahle Bayt of the Prophet are better than all Ahle Bayt who are created for guiding the people.
