I praise Allāh seeking completion of His Blessing, submitting to His Glory and expecting safety from committing His sins. I invoke His help being in need of His Sufficiency (of protection). He whom He guides does not get astray, He with whom He is hostile gets no protection. He whom He supports does not remain needy. Praise is most weighty of all that is weighed and the most valuable of all that is treasured.
I stand witness that there is no god but Allāh the One. He has no like. My testimony has been tested in its frankness, and its essence is our belief. We shall cling to it for ever till we live and shall store it facing the tribulations that overtake us because it is the foundation stone of Belief (imān) and the first step towards good actions and Divine pleasure. It is the means to keep Satan away.
I also stand witness that Muḥammad (S) is His. slave and His Prophet. Allāh sent him with the illustrious religion, effective emblem, written Book,  effulgent light, sparkling gleam and decisive injunction in order to dispel doubts, present clear proofs, administer warning through signs and to warn of punishments. At that time people had fallen in vices whereby the rope of religion had been broken, the pillars of belief had been shaken, principles had been sacrileged, system had become topsy-turvy, openings were narrow, passage was dark, guidance was unknown and darkness prevailed.
Allāh was being disobeyed, Satan was given support and Belief had been forsaken. As a result the pillars of religion fell down, its traces could not be discerned, its passages had been destroyed and its streets had fallen into decay. People obeyed Satan and tread his paths. They sought water from his watering places. Through them Satan's emblems got flying and his standard was raised in vices which trampled the people under their hoofs, and treaded upon them with their feet. The vices stood on their toes (in full stature) and the people immersed in them were strayed, perplexed, ignorant and seduced as though in a good house  with bad neighbours. Instead of sleep they had wakefulness and for antimony they had tears in the eyes. They were in a land where the learned were in bridle (keeping their mouths shut) while the ignorant were honoured.
ومنها: ويعني آل النبي ( صلى الله عليه وآله وسلم)
In the same sermon Amīr al-mu’minīn referred to Al an-Nabi (the Household of the Holy Prophet) as under.
They are the trustees of His secrets, shelter for His affairs, source of knowledge about Him, centre of His wisdom, valleys for His books and mountains of His religion. With them Allah straightened the bend of religion’s back and removed the trembling of its limbs.
None in the Islamic community can be taken at par with the Progeny  of the Prophet (Ãlu Muḥammad). One who was under their obligation cannot be matched with them. They are the foundation of religion and pillar of Belief. The forward runner has to turn back to them while the follower has to overtake them. They possess the chief characteristics for vicegerency. In their favour exists the will and succession (of the Prophet). This is the time when right has returned to its owner and diverted to its centre of return.
 The Preserved Record.
 Good House means ‘Mecca’ while the bad neighbours mean the ‘Unbelievers of Quraysh.’
 About the Progeny of the Prophet Amīr al-mu’minīn has said that no person in the world can be brought at par with them, nor can any one be deemed their equal in sublimity, because the world is overladen with their obligations and has been able to secure eternal blessings only through their guidance. They are the corner stone and foundation of religion and the sustenance for its life and survival. They are such strong pillars of knowledge and belief that they can turn away the stormy flow of doubt and suspicion. They are such middle course among the paths of excess and backwardness that if some one goes far towards excess and exaggeration or falls behind then unless he comes back or steps forward to that middle course he cannot be on the path of Islam. They possess all the characteristics which give the superiority in the right for vicegerency and leadership. Consequently, no one else in the ummah enjoys the right of patronage and guardianship. That is why the Prophet declared them his vicegerents and successors. About will and succession the commentator Ibn Abi’l-Hadid Mu`tazili writes that there can be no doubt about the vicegerency of Amīr al-mu’minīn but succession cannot imply succession in position although the Shi`ite sect has so interpreted it. It rather implies succession of learning. Now, if according to him succession is taken to imply succession in learning even he does not seem to succeed in achieving his object, because even by this interpretation the right of succeeding the Prophet does not devolve on any other person. When it is agreed that learning is the most essential requirement of khilafah (caliphate) because the most important functions of the Prophet's Caliph consist of dispensation of justice, solving problems of religious laws, clarifying intricacies and administration of religious penalties. If these functions are taken away from the Prophet's deputy his position will come down to that of a worldly ruler. He cannot be regarded as the pivot of religious authority. Therefore either we should keep governmental authority separate from Prophet’s vicegerency or accept the successor of Prophet’s knowledge to suit that position.
The interpretation of Ibn Abi’l-Hadid could be acceptable if Amīr al-mu’minīn had uttered this sentence alone, but observing that it was uttered soon after `Ali's (p.b.u.h.) recognition as Caliph and just after it the sentence “Right has returned to its owner” exists, this interpretation of his seems baseless. Rather, the Prophet's will cannot imply any other will except that for vicegerency and caliphate, and succession would imply not succession in property nor in knowledge because this was not an occasion to mention it here but it must mean the succession in the right leadership which stood proved as from Allāh not only on the ground of kinship but on the ground of qualities of perfection.
