Delaying hajj due to a concern that one's income may not be completely halaal

Q: Is it permissible for a person who is accredited for Hajj, and has both the means and opportunity to fulfill their Fardh Hajj, to delay it as he is concerned that their income may not be completely halaal? The individual intends to fulfill the obligation but wishes to ensure that they use only pure, halaal money for this sacred journey.

Doubts regarding ghusl

Q: I have issues with my ghusl concerning the validity of it due to specific barriers. 

I scrub my ears yet there is still some sort of wax at the part that curves. I sometimes scrub so hard it scabs. 

I also have some white patches in the middle of my chest. I’m not sure what it is but I also need to scrub hard for it to be removed. 

I have an ear piercing hole, how do I clean inside of it, if it’s closed but sometimes some sort of sebum comes out when I rub my piercing hole which is pretty much shut. I have some hard dirt on/in my bellybutton. It is extremely hard to remove as it’s engraved in the grooves of my skin.

Lastly I have an eye issue called blepharitis where dandruff like flakes are on my eyelash and eyelid. Sometimes I finish my ghusl and see these flakes/crust on my eyelid and lash. Are the things mentioned barriers for my ghusl?

Following the people who are adhering to the sunnah

Q: It goes without saying the recent indifference that has occurred in the tableeghi jammat with the one side having certainty on an ameer and his claims and Allah Ta'ala knows what more he says, and the shura side who Alhamdulillah is trying to take the work forward and leave the baatil. Would Hadhrat Mufti Saheb still advise going in jamaat with the shura side?

Reading aayatul kursi and blowing on family members who are living far away

Q: I have the habit of reciting aayat ul kursi (once) followed by the last three surahs 3 times each and then doing a dum on myself and my family members who are living in other places and countries by imagining their faces one by one and doing dum in the approximate direction. 

I would generally do that amal at any time of the day with the intention of safety and well-being of myself and the loved ones. I would like to know: 

1. Is such practice permissible and supported by some evidence? 

2. Is there any added significance and benefit of continuing this practice compared to normal masnoon prayers for self and family members? 

3. Or whether it's an innovation and should be avoided?

Serving one's parents while listening to their hurtful comments

Q: I left my home due to toxic and unjust family matters that were affecting me and my wife emotionally and mentally. I rented a home not too near not too far from my parents, and everyday I go to my parents house to do any work they want, as my father is a paralysis patient. Everyday I give him a massage and bath him and simultaneously listen to hurtful comments and smile and not reply so the atmosphere don't get more tense. Am I doing right or wrong and will any curse of my parents for me to Allah affect me?
