7 – And from Muhammad b. Ahmad as-Sinani from Muhammad b. Abi `Abdillah al-Kufi from Musa b. `Imran an-Nakh`i from his uncle al-Husayn b. Yazid an-Nawfali from `Ali b. Salim from Abu Basir. 
He said: I asked Abu `Abdillah عليه السلام about His عزوجل saying “And I did not create the jinn and man but to worship Me” He said: He created them to command them to worship.
He said: And I asked him about His عزوجل saying “but they continue in their differences save those whom your Lord has had mercy on” (11:118-119) He said: He created them so that they would do that by which they would deserve His mercy, so He has mercy on them.
