Imitating the kuffaar

Q: There was a fun run race this past month that is called colour run. Basically the people run a fun run where along the way colour powder gets thrown at the runners. This is a global event which is now becoming prevalent in the Muslim community. The purpose as per their website is celebrating healthiness, happiness and individuality. I would like if Mufti can maybe give a general view on the harms of doing such races and also expanding on the nature of which this is similar to a Hindu custom (Holi)?

Ghusal

Repentance and tawbah

Q: I have commuted zina by accident I want to repent for my sin and also I want to ask Allah what I can do (pay a certain amount of charity, fast for a certain amount of time, etc.) to make sure my sin is forgiven. I also want to get married to this person who has asked for my hand in marriage without him finding out about my sin so I was wondering if there is any way I can communicate to Allah for helping me and guiding me through this marriage.

Working for an Islamic Bank

Q: I was a Bank Manager in a Conventional Bank. I left the Bank after Allah Ta'ala blessed me with His guidance. Immediately after I left my Bank job, I got an offer from a person which was very good, almost too good to be true. I joined this person but as the days passed, all my savings from my previous Job were taken from me and I was left with nothing. Thereafter I remained jobless for almost 7 months after which I received an offer from a former acquaintance and I accepted. That job related to IT software very new to me but I managed to learn and work. After 4 years, the business turned bad and the company was dissolved. Now, I'm jobless again. Many people want me to join an Islamic Bank but I'm not sure if it is Islamic at all. I'm afraid that if I join the same sector, Islamic or otherwise, all the hardship I went through to get away from "Riba" would be useless. Please guide me about an Islamic Bank. Should I join?
