Zikr & Dua

Zikr in congregation

Q: Some people mention that it is bid’ah to engage in halqah zikr. Their proof is as follows:

It was reported to Hazrat Abdullah bin Mas’ood (radhiyallahu anhu) that a group of persons (non-Sahaabah) were sitting in a halqah (circle) in the Musjid reciting in unison 100 times Allahu Akbar, 100 times Laa ilaaha illallaah and 100 times Subhanallah, using pebbles for counting the number of times. In receiving this information Hazrat Ibnu Mas’ood (radhiyallahu anhu) went to the Musjid and found the group conducting their congregational zikr program. He exclaimed: “Count your sins on these pebbles. I guarantee then that none of your virtuous deeds will be destroyed. Alas upon you, O Ummat of Muhammad (sallallahu alayhi wasallam)! How quickly have you lapsed into destruction! There are still numerous Sahaabah among you; the garments of Nabi (sallallahu alayhi wasallam) have not yet become old nor have his utensils broken, but you have opened up the gateway of deviation.” (Musnad Daarmi)

Is there any response to this?

Hazrat Aasiyah (radhiyallahu anha) being the wife of Rasulullah (sallallahu alaihi wasallam) in Jannah

Q: I have heard that Hazrat Aasiyah (radhiyallahu anha) will be among the wives of Rasulullah (sallallahu alaihi wasallam) in Jannah, but I do not know whether this is true or not. Can I make dua to Allah Ta'ala to make me the husband of Hazrat Aasiyah (radhiyallahu anha) in Jannah?

Sending durood upon Nabi (sallallahu alaihi wasallam)

Q: I have a friend and his mom asked him, as she is jahil, is it permissible to send darood on Nabi Muhammad (sallallahu alaihi wasallam) and he said I don't know with respect because he thought that it may be shirk and then he said"Lekin kiya zaroorat he" with respect not with niyyat of disrespect. He said this because he thought it means that we are maybe asking from Nabi Muhammad (sallallahu alaihi wasallam) or something. Is this kufr?

Reciting toilet duas when going to the bathroom to make wudhu

Q: I have a question regarding the duas which are recited before and after going to the bathroom ("Allahuma innee a'udhu bika minal khubuthi.." and "ghufranak, alhamdulillahilladhi adhaba 'anni..").

Should these duas be recited if my purpose for entering the bathroom is to do wudhu in the sink or to take a shower? Or is it only if I enter the bathroom for going to the toilet?
