5. Muhammad ibn abu ‘Abdallah ibn Muhammad ibn Isma‘il has narrated from al-Husayn ibn al-Hassan from Bakr ibn Salih from al-Hassan ibn Sa‘id from al-Haytham ibn ‘Abdallah from Marwan ibn Salih who has said that Imam abu ‘Abdallah has said the following. “Allah created us and made it well. He gave us our form and formed it well. He made us His eyes among His servants and His speaking tongue in His creatures. He made us His open hands over His servants with kindness and mercy. He has made us his face through which He is approached and his door that shows the way leading to Him. He made us His treasurers in the heavens and on earth. Through us the trees give fruit and the fruits ripen and the canals flow. Through us the skies send rain and plants grow on earth. Through our worship Allah is worshipped and were we not there Allah would not have been worshipped.”

6. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Muhammad ibn Isma‘il ibn Bazi‘a from his uncle, Hamza ibn Bazi‘a from abu ‘Abdallah (a.s.) who has said the following about the words of Allah. “When they invoked Our anger, (43:54). We took revenge on them . .” (43:55). “Allah, the Most Holy, the Most High, does not become frustrated the way we do. But He has created friends for his-Own-self who become frustrated and at times happy. They are created. They worship (Allah). He has designed their happiness to be His Own happiness and their anger as His-Own anger. It is because He has assigned them to guide people to Him and serve as proof of His existence. For this reason such conditions belong to them. This does not reach Allah the way it reaches people. The meaning is what was just mentioned. He has also said, “Whoever would humiliate My friends such people have declared war against Me with challenge.” He has also said, “One who obeys the Messenger has certainly obeyed God. . .” (4:80). “Those who pledge obedience to you are, in fact, pledging obedience to God. The hands of God are above their hands. . .” (48:10). All of these and other similar ones mean what I just said. The same is the case with anger and happiness and other such matters. Had it been possible for frustration and anger to reach Allah one could have said that one-day Allah will banish altogether. It is because if anger and frustration would reach Him changes also would take place in Him and, thus, He will not remain safe from banishment. As a result, there would exist no distinction between the created and the Creator, between the Almighty and those subject to such might and power. No distinction would remain between the created and the Creator. Allah is far above such things, and is the Most High and Most Great. He is the Creator of all things not because he needed them. If it would be without the need then it would be impossible to limit Him with limits and conditions. Note this if Allah would will it to be so.”
