7. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Murazim ibn Hakim who has said the following
“Abu ‘Abd Allah (a.s.) ordered to write a letter about an issue. The letter was written and was shown to him and there was no exception in it. The Imam said, ‘How can you expect that this may be completed without exception (that is, if Allah so wills)? Look into it and write down exceptions whenever needed.”’
