Zikr & Dua

Proof of reciting prescribed azkaar by the Mashaayikh

Q: There are some specific prescribed Zikr by the Ulema and Mashaykh which are called "Wazifa". These are certain Azkaar of reading a Dua, or Ayah of Quran or the names of Allah for a specific number of times in order to achieve something. 

My question is that, do we have evidences from the Quran, Sunnah and the practice of the Salaf on practicing these prescribed Azkaar? Can you please list them in detail with references.

Not feeling the connection when making dua at the time of tahajjud

Q: Tonight I got up to pray tahajjud and when I started praying it felt like a tahajjud prayer though when I went into Sajda, I didn't feel the connection I thought I would, like I went to Allah in taha while crying and when I started praying all my tears were gone, I wasn't able to cry in my sujood. Does this mean I didn't pray it right?

As I checked that I did my wudu right and covered up my self right though still I feel something was missing.

Adding to that, I'm one day away from my periods and I also thought that the crying part was just from my mood swings which are a symptom of our period coming, because when I stood on the prayer mat all the tears went away.

Moreover, I had weird thoughts during the prayer like I wasn't praying right and had alot of skulls appearing in my thoughts (jinn like thoughts). Please share if there is a problem in this or am I just overthinking?

Reciting one hundred Durood after Fajr and Maghrib

Q: In the hadith below, do we have to recite this particular durood or can any durood be read.

Reciting One Hundred Durood after Fajr and Maghrib

Hazrat Jaabir رَضِيَ اللَّهُ عَنْهُ reports that Hazrat Rasulullah صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ said, "The one who recites one hundred Durood upon me immediately after performing the Fajr Salaah, before speaking, Allah تبَارَكَ وَتَعَالَى will fulfill one hundred of his needs. Allah تَبَارَكَ وَتَعَالَى will hasten the fulfillment of thirty needs (in this world), and Allah تَبَارَكَ وَتَعَالَى will keep the fulfillment of seventy in store for the Hereafter, and similar will be the case if one recites the Durood after the Maghrib Salaah (i.e. one will receive the same virtue)." The Sahaabah رَضِيَ اللَّهُ عَنْهُم enquired, "How should we recite Durood upon you, O Rasul of Allah صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ?" Rasulullah صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ instructed the Sahaabah رَضِيَ اللَّهُ عَنْهُم to recite the following Durood one hundred times:

إِنَّ اللَّهَ وَمَلئِكَتَهُ يُصَلُّوْنَ عَلَى النَّبِيِّ يَأَيُّهَا الَّذِينَ آمَنُوا صَلُّوْا عَلَيْهِ وَسَلِّمُوا تَسْلِيمًا اللَّهُمَّ صَلِّ عَلَى مُحَمَّد

Secondly, when reciting this durood, do we read the ayat as well or only اللَّهُمَّ صَلِّ عَلَى مُحَمَّد

Taubah for making inappropriate duas

Q: I was in hardship and in a desperate situation. I wanted my dua to get accepted so I asked God not to give me anything nor would I ask for anything in Jannah if God accept my dua. I think my dua got accepted but I feel a little regret. This is because I feel I'll lose out in the hereafter.

Can I do anything to reverse this? My life in dunya hasn't gone to plan and I don't want my akhirah to fail also.

Talking to Allah Ta'ala

Q:

1. Is it a sin and a spiritual disease to talk to Allah (SubhaanaHu Wa Ta'alaa) all the time verbally or in heart? Does it count as talking too much? And can one talk to Allah (SubhaanaHu Wa Ta'alaa) about things that are not related to Deen, like when someone see a bird or an animal or something permissible to see, they say to Allah (SubhaanaHu Wa Ta'alaa), "What a beautiful bird You have made."

2. How casually can one speak to Allah (SubhaanaHu Wa Ta'alaa)? I have had very little friends and I don't talk a lot with my parents nowadays. But, I speak casually to Allah (SubhaanHu Wa Ta'alaa) like He is a friend. I don't speak with disregard for His station, that is He is our Master. I also see Him like a child sees a parent, like a caretaker. Is it permissible to speak casually? I'll feel depressed if I can't.
