Question: What is the method of cleaning najasat?
Najasat (substances that Islam prescribes as dirty) can be cleaned out with any clean water, with water that has been used for wudu’ or ghusl, or with nonviscous liquids such as vinegar and rose water. Water that has been used for wudu’ or ghusl is called musta’mal (used) water. This water is clean but does not have the quality to clean hadath. That is, it can be used to clean najasat but cannot be used to perform wudu’ or ghusl.

Question: Before starting to perform wudu’, I saw a blood stain on my garment. I washed it, but its color remained. Does it affect the validity of my salat?

Question: When my clothes are washed with the clothes of other people during dry-cleaning, are my clothes contaminated by the najasat existing on the clothes of other people?
There is a possibility that your clothes might be contaminated by the najasat existing on the others’ clothes, but we cannot pass judgment based on sheer possibility. That is, they are assumed to be clean.
Question: If blood or urine falls into the water in a bucket, what should be done to purify it?
If clean water is added into the najis (impure) water and as much water as it contained has overflowed, it becomes clean all over. The overflowing water is clean unless the signs of najasat are noticed. If a najis bucket is filled and overflows, when none of the three signs [color, odor, and taste] of najasat is evident, both the water and the bucket become clean. (Radd-ul-mukhtar)
Question: A Muslim preacher of Bulgarian origin says, “After defecation, one must clean feces off the anus with a piece of toilet paper first. Then it should be washed with water. If one does not do anal cleansing in this manner, the hand contaminated by feces will not be clean even if it may be washed 70 times.” Is what he said true?
This is pure fabrication. Mostly non-Muslims follow this practice. They clean feces off their anuses with a piece of toilet paper and then spray them with a stream of water without ever touching them. The Muslim preacher you have mentioned may have witnessed this practice among non-Muslims or may have heard it from them. Feces cannot be cleaned with toilet paper. It is removed with the finger and then the finger is washed. After the cleansing of the anus completely, it is recommended to wipe it dry with a cloth or a piece of toilet paper. It is not obligatory to wash the hands with soap after going to the toilet. If the hands are washed only with water, najasat is considered to have been removed.
