In Islamic law, najis (Arabic: نجس) means ritually unclean. According to Islam, there are two kinds of najis: the essential najis which cannot be cleaned and the unessential najis which become najis while in contact with another najis.Contact with najis things brings a Muslim into a state of ritual impurity (Arabic: نجاسة najāsa, in opposition to ṭahārah, ritual purity). Ritual purification is then required before religious duties such as regular prayers are performed.
Thank you for your question. This answer is from the website of Ayatullah Sistani (hA):
Question: Does a woman enter the state of Janabah, if she reaches orgasm without penetration?
Answer: As for the fluid that is discharged from the vagina when a woman engages in foreplay or imagines lustful thoughts and which is not enough to dirty other places [such as her clothing], it is pure and does not require Ghusl to be performed and nor does it invalidate Wuḍū. However, if the discharged fluid is a lot – to the extent that it can be called an ‘ejaculation’ and it dirties clothing – then in case it is discharged when the woman reaches sexual climax and complete sexual satisfaction (orgasm), it is impure and causes Janābah. In fact, even if it is not discharged at that moment, based on obligatory precaution it is impure and causes janābah. And whenever a woman doubts whether or not a discharge of fluid was to this extent, or she doubts whether or not fluid was discharged at all, performing Ghusl is not obligatory on her and nor does it invalidate Wuḍūʾ and Ghusl.
May you always be successful
Every rule in Islam is based on our interest and avoiding us any harm. We do not know all the details of the reason but Allah (SWT) and the Prophet (SAWA) know the full reasons. We trust Allah and His Messenger and believe that dog is Najis because it is harmful for us to be in contact with dog.
Many medical scientists confirmed that many dangerous parasites can come to humans from contact with dog.
Journal of Medicine and Life stated : Dogs are a major reservoir for zoonotic infections.Dogs transmit several viral a bacterial diseases to humans.zoonotic diseases can be transmitted to humans by infected saliva aerosols,contaminated urine and feces and direct contact with the dog.
You need to wait till the blood stops, then perform Wudhu. If the blood does not stop, you put a bandage or plaster on it and perform Wudhu with wiping on the bandage.
After the Najasat is removed, shower water falling on the Najis areas is enough immediately to make your body Taahir with out need to go out of the shower and re enter.
Najasaat transfers 3 times from the impure object through wet contact
The Najis part of the blanket is the specific part which met Najis item with wetness and not all the blanket.
If your feet is wet and it touches that Najis part, then it becomes Najis and you need to wash it. Even if your feet is Najis and you walk on the ground, the ground will not be Najis unless your feet or the ground is wet.
Every solid item can be purified (Taahir) with water if it was not Taahir. Plastic utensils are no exception.
as salam alaikum
if you are in a state of impurity in the sense that you need wudu, ghusl or tayammum, which is technically defined as "hadhath", there is not transmission of impurity to the clean clothes that your wear.
If you have some impure substances on your body like urine, blood. etc., which is technically defined as "khabath", and such impurities get in contact with your clean clothes, then they will become impure as well and need to be washed.
With prayers for your success.
If you are sure that the impurity touched your clothes and made it Najis, but not sure about cleaning it, it is then Najis till you become sure that it have been cleaned.
Touching impure things or items e.g. urine, stool etc does not break nor invalidate your Wudhu. You just need to wash your hand with water to make it Taahir.
After completely removing the actual Najasat, the Najis couch or bed or item must be washed with water, one time with Kurr water (big quantity or current water) or three times with small quantity of water/
