Nawaafil

Q: According to the Hanafi Mazhab, is it better to perform nawaafil in the home or musjid?

Q: A mosque in Durban encourages Salatul Tasbeeh during holy/auspicious days and nights etc. I am familiar with the blessed status of salatut tasbeeh and its importance. The people are encouraged to read in the mosque and the imaam or some person counts the tasbeehs for them. He is not in salaah. Is this permissible?

Q: If a person prays nafl salah without wudhu, will he have to repeat it?

Q: What are signs of acceptance of dua or your hajat prayer? And what is the best way/wazifa to ask from Allah Ta'ala?

Q: What is Salaat-ut-Tasbeeh and when and how to perform it?

Q: I am a follower of the hanafi madhab and I am not a ghayr muqallid. Dear mufti i would like to know if it is permissible to offer nafl salah according to another madhab. I apologise if my question is not suitable​.

Q: I heard that if one prays two rakaats salaat e Haajat at Tahajud time and in the first rakaat after sura e fatiha one recites Rabbana Ateena
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. JazakAllah.

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: 

1. Will it be permissible to read Nafl salaah after the time of Fajr has come in before performing the Fajr Salaah?
2. If it is permissible, can we perform Nafl Salaah after the Sunnah of Fajr while waiting for the Fardh?

Q: Ishraaq and Chaasht prayer, is it more virtuous to read at home like other nawaafil or more virtuous in the masjid?
