Q: I would like to know, sometimes our duas are not accepted by Allah, we don't get solutions for our problems, even after doing lot of dua. Is there any particular method in asking for dua, or is it because of the sins performed in the past knowingly or unknowingly? I know nothing will happen to our wish, but still is there any particular thing to be done, so that our halal duas get accepted?

Q: I am a bit confused about doing zikr loudly. After fajr in my local masjid (Deobandi) people usually do zikr loudly, and also in some spiritual gatherings I have taken part in (Chisti tariqa, with a Deobandi Sheikh) we do zikr loudly in group (by saying "laillaha... illa Allah" and "Allhu"). However, I have now come across that Imam Abu Hanifa considered loud zikr to be a bida'. Can you please clarify the matter?

Q: What is the purpose/significance of durood Akbar (Allahumma Salli Ala muhamadin Sayyid ul mursaleen) as well as other Durwood found in the last pages of the smaller version of the quran.
