Issue No.6- When one is unable to identify the most learned Mujtahid, he should follow, as an obligatory precaution, a Mujtahid he supposes to be the most learned and if he entertains a doubt and cannot prefer between them, he can follow any of them.
Issue No. 8- If one suspects that the verdict of the Mujtahid might have changed, he can keep acting according to the previous one and investigation is not necessary.
Issue No.11- It is not permissible, as an obligatory precaution, to act on the fatwā of a dead Mujtahid initially, even though he might be the most learned of Mujtahids.
Issue No.13- If a person faces a problem whose rule is not known to him, he can exercise precaution, or if its time does not expire he should wait until he has access to a Mujtahid, and in case he has no access to a Mujtahid, he should act on what he thinks to be the fatwā of the Mujtahid and should inquire about it later. Then if he finds his act to be in conformity with the fatwā of the Mujtahid, it is valid, otherwise, he should perform it again.
Issue No.15- If a person has made an error in relating the fatwā of a Mujtahid and later realises his error, it is necessary for him to inform the people about the correct fatwā and if he has said it on a pulpit or in a speech, it is necessary for him to mention the correct fatwā in different sessions so that those who have fallen into error may come out of it. However, if the fatwā of the Mujtahid has changed, it is not necessary for him to inform others about it.

Issue No.27- If an original najis substance (like blood) reaches water which is more than kurr and changes a part of it, in the case of the unchanged part amounting to one kurr or more, only that part which has changed will be najis, otherwise the entire water becomes najis.
