Correcting a musallee who causes a disturbance in the musjid

Q: I have a few questions regarding a musallee and his children that come to the Musjid for Namaaz.

1. If a musallee becomes abusive and uses bad language on the Imam of the Musjid, and this was also mentioned in the presence of a Senior Aalim.

2. A musallee screams and shouts at an elderly Aalim regarding his Jumah Bayaan, this screaming and shouting is done in the presence of his children and in the Musjid premises.

3. Has no respect for the Musjid. He goes to the gas heater to warm his private parts by lifting his kurta up in the presence of all.

4. He reads his Sunday namaaz on the Imams Musalla.

5. He sits on the Mimbar and receites whatever he wants to receive.

6. He allows his children to stand next to the Muazzin who is giving Iqaamah, as he feels his children have the right to stand there.

7. He wants his children to correct the Imam during Fard Salaah even though they are not qualified Hafez.

8. He screams and shouts and utters vulgar language to any musallee and even went to the extent of accusing them that they are discriminating against him.

9. He reads his Sunnat namaaz anywhere in the Musjid even in the Mehrab and also at times moves the elderly out just so that he can prove he read on all the musallas in the Musjid.

What will the ruling be on the above matter. Can such a person still be allowed to come to the Musjid. By the way he only comes for Fajar and Jumah Salaah.

Drinking water instead of gargling the mouth when making ghusal

Q: I performed fard ghusl. I performed the two fard of washing my whole body and putting water in my nose but before I rinsed my mouth, I drank a glass of water (to fulfill the obligation of gargling, as I was advised to drink a glass of water to fulfill the gargling) but then I forgot about rinsing my mouth. I rinsed my mouth the next day when I remembered but did not gargle as I had already drank water the day before it to suffice for gargling. So is the fard of washing the mouth now complete and my ghusl valid? 

Receiving interest money

Q: If x person doesn't have a good income in his business and his business is going in a loss. He doesn't have any other source of income. This x person has a relative who has some money saved in a bank. The bank gave interest to x person's relative for his money in the bank. Can the relative give this interest amout to x person? 

The attributes of Allah Ta'ala

Q: I read this somewhere:

Also, As-Suddi said, "When a man would come to the two angels they would advise him, `Do not fall into disbelief. We are a test.' When the man would ignore their advice, they would say, `Go to that pile of ashes and urinate on it.' When he would urinate on the ashes, a light, meaning the light of faith, would depart from him and would shine until it entered heaven. Then something black that appeared to be smoke would descend and enter his ears and the rest of his body, and this is Allah's anger. Isn’t Allah’s Anger His Attribute alone so how would it enter a human being?
