Zikr & Dua

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?
