Drinking coke and pepsi

Q: My question is about consuming coke and pepsi as both of them are not certified by any certifying body like MJC, sanha as they also don't reveal their recipe of the drink which they claim a trade secret. They are right, they have to protect their business. But as Muslims where we remain cautious of consuming halaal food only, is it permissible to drink coke and pepsi?

Making a condition that the husband cannot remarry

Q: I just wanted to ask a question. I am having my nikaah done at the mosque in a week. I have researched upon the topic of allowing your husband to remarry. I wanted to have a condition in my nikaah that my husband should not remarry whilst he is married to me. If he was to do so and hide it from me he will be negligent upon his part. My query is where I live we don't have any blank space etc on the nikaah form to write such a condition. Is it enough for me to just mention it to my husband at the time of nikaah or before etc? He is already aware this is what I want as I have told him before. But online I have read on many sites that you should mention these things at the time of the nikaah otherwise it will not be valid? Please tell me how I should go about it.
