fid dunya Hassanato Wafil Aqirat e Hassanaton Wa Qina Azaabun Naar. Only this Ayat countinously as much as he can if possible 1/2 - 1 hour and do the same thing in the second Rakaat and after finishing the salaat and salaam and recites the same Ayat unlimitedly while sitting and after that he prays for any purpose it will be accepted, when I heard this I decided to recite this Ayat for at least 5 minutes in both Rakaats if I could'nt recites for One hour.  Please Advice me on this.

Q: 

1. I am over conscious about purity and cleanliness. Even though I do my best to wear clean clothes, have clean body and wudu properly so I can offer salah perfectly but I always have doubt about cleanliness. I feel if I touch most things I'll get germs I have to repeat my wudu again. I can't able to do wudu any place anywhere I worry about cleanliness of the place. I have 3 different clothes, I wear 1 set of clothes for toliet, I have 1 set of clothes for going out and I have 1 set of clothes for praying salah.  I worry that if I wear same clothes that I went to toliet with that clothes wouldn't be clean for salah.  I wear sandals at home because I don't want to get germs or dirt from carpet.  I try to avoid touching the door handles so I don't want to get infected with germs. I get thoughts  place where I pray it's not clean enough. If some else prays on my praying mat (carpet) I feel that person made my mat dirty I have to wash it. I waste too much water and long time in wudu and ghusl. I follow the tiny things that are not even seen by eyes to clean them and remove them. After I do wudu I get thoughts like I didn't do wudu properly or I didn't wash 3 times each part of body or I have to repeat wudu again because I was bit careless when doing wudu.  These thoughts I get do I have to accept them or ignore them? I feel if I don't listen to these thoughts my prayer will not be valid?
2. How do keep yourself clean but not trying too hard or listening to shaytaan whispers?
3. I am pretty sure I am suffering waswasas with regards to cleanliness, how can I stop these thoughts?

Q: What are fazaail-e-Aa'maal, fazaail-e-sadaqaat and fazaail-e-durood and where can I get information about them?

Q: I am a Muslim working with a non-Muslim in an exhibition show. He is selling antiques which relate to all religions e.g. Buddha statues, Christian crosses, items decorated with the names of Allah Ta'ala, etc.  My job is loading, unloading and security, and I keep these things in a showcase. Is my job with this man halaal or haraam?

Q: I read the hadith "The difference between us and the pagans is that we wear the 'imama on top of the qalansuwa" (Abu Dawud). Does this mean that the mere wearing of a topi resembles the practise of the pagans and that it is better for us to wear imamas? The only problem for me wearing an imama is that it is uncommon amongst the Muslims where I live, most people including elders and teachers wear topi, and I am afraid that I give myself a higher rank than I am worth if I wear an imama. Is this a valid excuse not to wear an imama?

Q: We understand that when a person undertakes a journey for a distance of more than 48 Miles/77 km from his city of residence, he is required to offer only 2 Rakaahs of Fard Salaah, if offered alone, up to 19 days of his stay in another city, as confirmed in Sahih Hadith. But, for those who regularly offer Tahajjud Salaah, should they continue offering Tahajjud Salaah for those 19 days while they are in a state of journey to another city? Or is there an exception for them. Please clarify.

Q: I have few farz rozas due to keep from last ramazan because of monthly period and one of them I left because of severe migraine headache.
Most of the time when I fast I have severe migraine headache with nausea which is quite severe. My question is can I give fitr for the above rozas or do I need to keep it despite the headache.

Q: 

1. In 2 rakaats of Nafl Salaah, is it permissible to make multiple niyyahs for the salaah? Eg. Salatut Taubah, Salatul Haajat and Salaatus Shukar - all for 2 rakaats only. Or is every Nafl Salaah limited to one niyyah alone? 
2. I am a Hanafee. Once in a while, during my Nafl Salaah that I read alone, usually at home, I make "Rafa' Yadain" with the intention of practising upon the hadith on the authority of Abdullah bin Omar (Radiyallahu Anhuma) in which Nabi (Sallalallahu alayhi wa salam) did Rafa' Yadain, which appears in Bukhari ​Shareef. It is not a constant practise of mines, but rather once in a while, in seclusion, do I practise this. I understand that as Hanafee's it is more virtuous not to do it, but I enquire with regards to permissibility. Can I continue doing this once in a while? If not, were all my past nafl salaah's considered invalid because of this?

Q: A couple engaged in a mut'a marriage. They realized after some time that mut'a is not allowed. Is their nikaah valid or should they perform another nikaah?

Q:

1. I have witnessed many Muslims standing up when they drink Zam Zam Water. Those who sit and drink are being ridiculed by many people and even Mullahs who justify that we must always stand up while drinking Zam Zam Water. 
2. I have also witnessed many people standing/walking while drinking water and eating dates in Haram Sharief in Makkah. But, the Sunnah of Rasul Allah Sallallaahu Alaihiwa Sallam is that we must always sit while drinking or eating. Please clarify in detail.
