1. Muhammad ibn abu ‘Abdallah and Muhammad ibn Yahya - both in a marfu‘ manner- have narrated from Imam abu ‘Abdallah (a.s.) who has said the following. “Imam Amirul Mu’minin mobilized people against Mu’awiya for the second time and when people came in multitudes he stood up to give a speech.
‘All praise is due to Allah, the One, only One, the Self-sufficient, the Single one Who did not come into being from anything and was not created from something that had come into being before. He is the power. With His power He is distinct from others and the other things became manifest through His power.
There is no attribute that would reach Him and He has no limit for a definition or an analogy. All the linguistic beauty and expressions fall far short to express His attributes. In speaking of Him all attributes prove to be misleading. The depth of the schools of thoughts are perplexed and confused about the wonders of His kingdom.
All the comprehensive interpretations have remained far short of establishing any footing in His knowledge. The barriers of the unseen have curtained His treasured secrets. The high flying ambitious intelligence with the ability to reach the depth of very subtle matters lose their way at the very beginning of their journey to Him.
Most Holy is Allah. To Him not even the far-reaching ambitions are able to reach. No deep diving intelligence is able to comprehend Him. Most High is He Who is not subject to the effects of any calculated time or extended period or limited attributes. Glorious is He Who has no beginning for His start, a destination to approach or an end to diminish. Glorious is He Who is just the way He Himself has introduced.
All those who speak of His praise can never praise fully and duly. He designed a limit for everything at the time He created them. It is because that there is no similarity between them and He and that because He is not similar to any thing else. He is not absolved in anything so that it could be said He is within anything and He is far from anything so that it could be said He has nothing to do with them (the creatures). He has not distanced Himself from them so that it can be said where is He? He is far Glorious (and above such associations).
He has encompassed all things through His knowledge. He has made their design firm and has enumerated them for safe preservation. Even the unseen and hidden things in the air, is not unnoticed to Him. Nor things deeply hidden in the darkness of black nights, all things high above in heavens and down to the lowest earth are not unnoticed to Him.
For everything there is a protector and a guard and everything therein has limits within something and a limit for that limit. He is the One, the only One, the self sufficient, Who is not subject to the changes due to times.
The creation of things never over burdens Him. He only, when willing, commands it to exist (and it comes into existence). He invented whatever He has created without any examples to follow and without feeling of over burdened or exhaustion. All manufacturers manufacture things from something. Allah has not created whatever He has created from anything.
Every knowledgeable one learns after being ignorant. He has not being ignorant and has not learned from any one. He has encompassed all things through His knowledge before their coming into existence and their existence has not increased any thing to His knowledge. He knew them before their coming into existence just as He knows them after their coming into existence.
He did not bring them into existence to strengthen His authority or for fear of banishment or reduction. He did not bring them into existence as helpers against a competing opponent, and a peer who would be of more (power) or a partner who would show greatness. He created them as creatures that required preservation and protection as subdued servants. Glorious is He, Who does not become tired in the creation of what He has created or the preservation of all that He has formed into beings. He does not undergo in this work any weakness or exhaustion. Whatever He has created has deemed it sufficient. He knows what He has created and created what He knew. It did not happen as a result of new thinking that He found to be a correct one not because of some doubts that He may have found in whatever that He had not yet created. It is due His unchangeable decree, His firm knowledge and resolute command.
He is the One only Lord and is very special in His Oneness. He is pure in His Glory and praise. He is the only one in Oneness, the Glory, in Highness, in Oneness in praiseworthiness and in Glory and Gloriousness. He is Far High above having children. He is far Holy and clean above involvement in touching women and by far Majestic and Glorious above the association of the partners.
In whatever He has created there is nothing to oppose Him nor there is any thing in what He created to stand parallel to Him and no one shares Him His kingdom. He the One and only the Self-sufficient, Who brings the timeless time to an end, is the owner of the extended duration of time.
He is the one Who is eternal with eternal Oneness before the beginning of the times and after all the changes in the creation. He is the one who never banishes or diminishes. Thus, I speak of my Lord.
There is no lord besides Allah. He is the Great and of un-matching greatness. He is the Most Majestic and of unmatched Majesty. He is the Most Glorious and of unmatched Glory. He is far above what the unjust think of Him to be.”
