1. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from abu Ayyub from Muhammad ibn Muslim from abu ‘Abdallah (a.s.) who has said the following. “The Jews asked the Messenger of Allah (s.a.), ‘Describe for us the genealogy- of your Lord.’” The Prophet waited for three days and gave no reply. Then the following verses were revealed to him: In the Name of Allah, the Beneficent, the Merciful (Muhammad), say, “He is the only God (112:1). God is Absolute (112:2). He neither begets nor was He begotten (112:3). There is no one equal to Him (112:4). The same Hadith has been narrated by Muhammad ibn Yahya from Ahmad ibn Muhammad from Ali ibn al-Hakam from abu Ayyub.

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa and Muhammad ibn al-Husayn from ibn Mahbub from Hammad ibn ’Amr al-Nusaybi who has said the following. “I asked Imam abu ’Abdallah (a.s.) about the words of Allah, ‘Say, ‘He is Allah, One . .’” The Imam replied, “These verses define Allah’s relation to His creation. He is the One, Unique, Eternal, and Absolute. He does not have shadow so one can hold Him but it is He who holds things by their shadows. He knows the unknown and is known to every ignorant person. He is only One. He is not in His creatures and His creatures are not in Him. He does not feel nor others can feel Him (physically). Eyes cannot see Him. He is so High that is near and is so near that He is far. Although disobeyed, yet He forgives. When obeyed, He is appreciative. His earth does not contain Him, nor do His heavens bear Him. He holds all things through His power and He is Everlasting and Eternal. He does not forget or amuse Himself. He does not make any mistakes or play. There is no lapse in His will. His judgment is rewarding and His commands are effective. He does not have a child to become His heir nor is He begotten so His power would be shared. And there is no one like Him.”

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Nadr ibn Suwayd from ‘Asim ibn Hamiyd who has said the following. “I asked Imam Ali ibn al-Husayn (a.s.) about the Oneness of Allah. The Imam replied, “Allah the Almighty, the Great, the Exalted knew that in the latter times there will be people who would investigate the issues very deeply in a hair splitting manner. Therefore, Allah, the Glorious, has revealed chapter one hundred twelve of the holy Quran that speak of the Oneness of Allah. He has also revealed the verses of the chapter fifty seven of the holy Quran In the Name of God, the Beneficent, the Merciful All that is in the heavens and the earth speak of the glory of God. He is Majestic and All-wise (57:1). To Him belongs the Kingdom of the heavens and the earth. He gives life and causes things to die. He has power over all things (57:2). He is the First, the Last, the Manifest, and the Unseen and He knows all things (57:3). It is He who created the heavens and the earth in six days and then established His Dominion over the Throne. He knows whatever enters into the earth, what comes out of it, what descends from the sky, and what ascends to it. He is with you wherever you may be and He is Well Aware of what you do (57:4). To Him belong the heavens and the earth and to Him all things return (57:5). He causes night to enter into day and day into night. He knows best what all hearts contain (57:6). Whoever would accept any thing otherwise he is destroyed.”

4. Muhammad ibn abu ‘Abdallah in a marfu‘ manner has narrated from ’Abd al-‘Aziz ibn al-Muhtadi who has said the following. “I asked Imam Ali al-Rida (a.s.) about the Oneness of Allah.” He replied, “Whoever recites Chapter 112 of the holy Quran: In the Name of Allah, the Beneficent, the Merciful (Muhammad), say, “He is the only God (112:1). God is Absolute (112:2). He neither begets nor was He begotten (112:3). There is no one equal to Him (112:4). and also believes in it, he has really acknowledged the Oneness of Allah.” I asked, “How should I recite it (the chapter 112)?” The Imam replied, “Recite it as the people do.” And then the Imam added, “Such is Allah, my Lord. Such is Allah, my Lord.”
