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.16- It is not permissible to switch from one Mujtahid to another as an obligatory precaution unless the second Mujtahid is the most learned. And if he has switched without investigation, he must switch back.
Issue No.18- If a person has been following a Mujtahid for some time but does not know whether his Taqlīd has been correct or not, there will be no problem with the acts he has performed already, but he must follow a Mujtahid in a correct way for his present and future practices.
Issue No.24- If original najis like urine or blood falls in kurr water and the water acquires the smell, colour, or taste of that najāsah (najis substance), it will become najis, and if not, then it will not be najis.
Issue No.25- If something that has become najis (such as clothes or a container) is washed in kurr water, it will become ṭāhir.
Issue No.26- If the smell, colour, or taste of kurr water changes owing to something else which is not najis, it does not become najis. However, it is always better to avoid dirty water.
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.
Issue No.28- If a najis object is washed under a tap which is connected to kurr, the water which falls from it is ṭāhir, unless it acquires the smell, colour, or taste of the najāsah.
Issue No.29- If the quantity of an amount of water was equal to kurr or more, and later on one doubts whether it has reduced to less than kurr, it will be treated as equal to kurr. On the contrary, if water was less than kurr, and later, one doubts whether it increased to the amount of kurr, it should be treated as less than kurr water.
Issue No.29- If the quantity of an amount of water was equal to kurr or more, and later on one doubts whether it has reduced to less than kurr, it will be treated as equal to kurr. On the contrary, if water was less than kurr, and later, one doubts whether it increased to the amount of kurr, it should be treated as less than kurr water.
Issue No.36- If najāsah reaches flowing water, only that part of the water will be najis whose smell, colour or taste changes on account of it, and the end which is connected to the spring will be ṭāhir even if it is less than kurr. However, the water on the other side of the canal will be najis if it is less than kurr, unless it is somehow connected through the unchanged portion of the water to the spring.
Issue No.37- Stationary water that refills every time water is drawn from it is treated as flowing water and does not become najis if najāsah reaches it, even though it may be less than kurr. The ruling applies, as well, to the stationary water at the bank of a creek which is connected to the water of the creek.
