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.
Such drops are Taahir ( ritually clean).
'Every thing is Taahir for you unless and until you know for sure that it is Najis.
As you did not know that your ritual purity was not valid when you performed your prayers, there is no sin on you if you had a valid reason of not knowing, but you need to redo those invalid prayers. After performing those prayers,no your responsibility will be clear.
Allah (SWT) Has kept every Infallible totally pure, and kept any type of impurity far away from them, not that Allah has removed impurity from them, but kept them far away from any impurity i.e. Allah did not allow any impurity whatsoever to come near any Infallible. Quranic verse 33:33 stated: In fact, Allah wants to keep impurity away from you O, Ahlul Bayt إنما يريد الله ليذهب عنكم الرجس أهل البيت
There is a big difference between ليذهب عنكم to drive away any impurity from coming near you, and ليذهب منكم which means to drive away impurity from you which can mean driving away any existing impurity. Allah (SWT) never said that, but He said ليذهب عنكم which means that Ahlul Bayt never had any impurity, and Allah kept impurity far away from coming near them.
All the existence of the Infallible is absolute pure in the highest level which can never be compared with ordinary pious people.
These facts are very clear in Quran and the authentic Hadeeths. After believing in these facts, we do not need to go into details of the personal life of the Infallible, which are not necessary for us as it has nothing to do with our faith and practice and our responsibility to be sincere and humble servants of Allah and obedient followers of the Prophet (SWT) and Ahlul Bayt(AS).
The Quranic letters should not be touched by you nor touch your body during menses and when you have no Wudhu. Carrying it on pendant is permissible as far as it does not touch your body nor amount to any type of disrespect.
Asalamu Alaykom, if najasa was still on some of the clothes then you need to rewash them again as they would be najis.
If only colour remains, then it wouldn't be necessary to rewash. For example you had some clothing with blood on it and the red stain remained while the actual substance was removed. In such a case the item would be tahir and colour wouldn't be an issue.
May Allah grant you success
Very little to add here!
I just wanted to say that there are times in life when it is good to go the extra mile, and there are times in life when you just have to focus on the basics. I am going to guess that, since you are living in a hostel, you are probably not in the best personal or financial situation and have other priorities.
So, it's great if everything around you can be tahir. It's not good to live around najasa like alcohol. I knew a woman once who was extremely proud of the fact that her entire house, including the toilet, was always tahir. (To which my other friend said, "Is she planning to eat from the toilet??")
On the other hand, as Seyed Ali Shobayri mentioned, the main sources of concern are: (a) eating and drinking (so, for instance, washing shared cups before using), and (b) purity regarding prayer. Everything else is excellent but may not be your priority right now.
I hope you are able to find a living situation where you have more control over your environment in the future!
Usually in a hostel one has their own room but may share a bathroom or kitchen with others. The general rule is that everything is tahir until you see it become najis, so assuming someone made something najis just because they don't know the tahara rules isn't correct. Let's say you do know some things become najis, it isn't wajib for you to make them tahir. You may keep your own pure utensils and also pure clothing for salah. As long as you keep a pure place for salah such as a rug and pure clothing then this is fine. One may also pray on a najis carpet apart from the sujud area provided that the najasa wouldn't transfer on them and remains dry.
May Allah grant you success
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
