acceptance of dua

Q:

1. What is the reason why wazifas don't work for some people and what are the conditions needed to make sure it works?

2. If you don't pray salah, will Wazifa never work or will it just work very slowly? What if you pray but not punctual?

Q: I really want something and I've been making a lot of dua for it. Also, I started performing tahajjud salaah for it. I need it urgently. How would I know that Allah will accept it or not?

Q: I am so lost I cry everynight for guidance for a little sign from Allah and I beg Allah to help me but nothing ever happens. I begin to wonder if, when you die, that's it, the end. What if Allah is not there but somthing else is?

Also, would you advise to stop watching videos online as they have misguided me and my iman before.

Q: Kindly tell me an effective ism-e-azam for the qabooliyat of dua.

Q: I am tired of all. I ask dua but they were never get answered. For the past 3 years nothing was answered. But I never lost hope. I ask again but nothing happened. So nowadays my Imaan is becoming worst. Does Allah love me? Because my duas never get accepted. Those who never do any amal, they are living happily. My life is getting worst day by day. Allah said in Quran "For indeed, with hardship [will be] ease." I believe these words. But it never happened in the last 3 years!

Q: What is the best way to ask for something in dua from Allah, even if it seems like the thing is not in our fate? No doubt Allah does the best for us but if we want to ask for something in dua, please tell me some nafil or amal with which Allah grants me what I ask Him for.

Q: I am making dua since last 6 month but its not getting qubool. I think the dua is getting stuck, So what should I do?

Q: Muhammad (Sallallahu Alayhi Wasallam) said in three situations, if you pray dua it is definitely accepted, when your body starts shaking, when you got fear in your heart, when you got tears in your eyes. Whoever shares this knowledge, he will have a house in front of mine. Is this Hadith true?
