2. [2/372] al-Kafi: A number of our companions from Ahmad b. Muhammad b. Khalid from his father from Ibn Abi Umayr from Muhammad b. Humran from Abi Ubayda al-Hadhdha who said: Abu Ja’far عليه السلام said: O Ziyad - beware of argumentation because it creates doubt, nullifies deeds and degrades its initiator, and it may happen that a man speaks something for which he is never forgiven. There was in days gone by a people who abandoned studying what they were entrusted and sought the knowledge of what they were asked to refrain from, until their talks turned to Allah and they became confused, so much so that a man would be called from in front of him but he would answer the one who is behind him and he would be called from behind and would answer the one in front.

3. [3/373] al-Kafi: Muhammad b. Yahya from Ahmad b. Muhammad from Ibn Abi Umayr from Abd al-Rahman b. al-Hajjaj from Sulayman b. Khalid who said: Abu Abdillah عليه السلام said: Allah Mighty and Majestic says: “and to your Lord is the End (finality)” (53:42) so if your talks reach to Allah then remain silent.

4. [4/374] al-Kafi: Muhammad b. Yahya from Ahmad b. Muhammad b. Isa from Ibn Fadhal from Ibn Bukayr from Zurara b. A’yan from Abi Abdillah عليه السلام who said: There was a king of great status who was in a council of his when he touched upon (started discussing) the Lord Blessed and Elevated. Suddenly he disappeared and it was not known where he was (could not be found).

5. [5/375] al-Kafi: Ahmad b. Idris from Muhammad b. Abd al-Jabbar from Safwan b. Yahya from Abi Ayyub from Muhammad b. Muslim from Abi Abdillah عليه السلام who said: The Jews asked the Messenger of Allah صلى الله عليه وآله saying: Relate for us the geneology of your Lord. So he (the prophet) remained three days not answering them then it was revealed “Say: He is Allah the One” to its end (112:1-4).

6. [6/376] al-Tawhid: Ibn al-Walid from Muhammad al-Attar from al-Ash’ari from al-Maythami from Safwan b. Yahya from Abi Ayyub from Muhammad b. Muslim from Abi Abdillah عليه السلام who said: The Jews asked the Messenger of Allah صلى الله عليه وآله saying: Relate for us the geneology of your Lord. So he (the prophet) remained three days not answering them, then it was revealed this chapter (Surat Tawhid) to its end. I (Muhammad) said: What is the meaning of Samad? He said: The one who does not have cavity.

7. [7/377] al-Tawhid: My father from Sa’d from Ibn Isa from Ibn Fadhal from al-Halabi and Zurara from Abi Abdillah عليه السلام who said: Allah Blessed and Elevated is One, Compact, He does not have any hollowness, while the spirit is a creation from among His creations and is an aid, support and power which Allah places in the hearts of the messengers and believers.

8. [8/-] al-Kafi: Muhammad b. Yahya from Ahmad b. Muhammad from al-Husayn b. Sai’d from al-Nadhr b. Suwayd from A’sim b. Humayd who raised it - he said: Ali b. al-Husayn عليه السلام was asked about Tawhid (Unity of God) so he said: Allah Mighty and Majestic knew that there would in the last age peoples who delve deep (wanting to know) so Allah the Elevated brought down “Say: He is Allah One” (chapter 112) and the verses in Surat al-Hadid until His words “and He is Knowing of that within the hearts” (57:6) so whoever looks (desires) beyond that then he has perished.
