Zikr & Dua

Q: Are these words shirk "Hasbunallahu wa ni`mal wakeel" and "Azizun qaaf qawiyyun latif"?

Q: Is it disliked to make dua for something that is highly improbable?

Secondly, does making dua such as 'oh Allah, grant jannah to all of the ummah' count as improbable since some people will inevitably go to jahannam? Or asking Allah to protect all of the our brothers and sisters from Allah all sorts of harm - is this also improbable?

Q: In Istikhara dua in some books it says Faqdirhuli and waqdir liyal Khair with a kasra (zer) under the daal, in other books it says Faqdurhuli and waqdur liyal Khair with a dhamma (pesh) on top of the daal, are both correct?

If not, which one is correct, daal with a dhamma or kasra in both places?

Could you please write the whole Istikhara dua with the correct Harkat?

Q: There's a kind of tradition in our family. Before any of our important work or board exams, all our relatives sit together and pray to Allah for our wishes to be fulfilled. Someone said that it's bidah or haram. Is it actually haram?

Q: A person has a bathroom with a sink, shower, etc. The toilet is enclosed in a shower door type enclosure. So the rest of the bathroom is not considered the toilet. Would it be correct to recite duas etc. there when making wudhu? Will it be fine to take a Quran inside the bathroom, recite Quran there whilst watching children in the bath? Not in the toilet, but in the rest of the bathroom.

Q: Is the eighty durood that is recited after Asr on Friday a practice which is established in Deen? Does it have a source in the Hadith of Rasulullah (sallallahu alaihi wasallam)?​

Q: My Question is that why we say 'Peace Be Upon Him' for Holy Prophet? Is Holy Prophet not in peace and safe?

In the Holy Quran Allah says that when beleivers come to you say to them ''salam alaikum - may you be safe" so this verse is for living people not for those who have passed away and we are sure that Holy Prophet is safe and in peace. So why "Sallallahu Alaihi Wasallam"? As generaly given refrence is that Allah says in Holy Quran that I read and My angels read salat to Holy Prophet so you should also read but actually the sense and meaning of this verse is "I and My angles help Holy Prophet and you should also help him" Please explain.

Q: Can you please tell me about durood e tunjeena? Is it an authentic durood? Can someone recite it?

Q: Can a Muslim boy pray to Allah to marry a Hindu girl? For example he says like this "Ya Allah, give her hidayat so that I can marry her.
