Halaal status of meat products exported from Brazil

Q: As we are aware, Brazil exports meat and meat products worldwide. Even within the Arab countries, these products are exported and, according to my information, they are halaal certified. As a result, many Muslims consume these products. 

However, I have noticed that our Ulama forbid consuming them. I have some questions regarding this: 

1. What is the position of our Ulama on Brazilian chicken, regardless of the brand? 

2. Are there certain brands that are genuinely halaal? 

3. On what basis is meat exported to Muslim countries and certified as halaal? 

4. Why do our Ulama and the Arab Ulama differ on this matter?

Continuing a marriage if the mahr (dowry) has not been paid

Q: Is it permissible to continue a marriage if the mahr (dowry) has not been paid? 

I am currently married, but my husband has not yet paid the agreed-upon mahr (dowry). I would like to know if my marriage is still valid in Islam without the payment of mahr. What steps should be taken in such a situation? Is the marriage still considered valid, and what are the Islamic guidelines regarding mahr payments? Should I take any specific actions to address this issue?

Husband sending text messages to his wife: "Go, I release you" and "I have no claim on you; you can live your own life."

Q: My husband said to me in a text message: "Go, I release you" and "I have no claim on you; you can live your own life." 

Does this count as a valid divorce (talaaq) according to Islamic law? I want to know if these words constitute a clear divorce or not. 

Wearing underwear in the state of ihraam due to urine incontinence

Q: My father has a small problem with old age and urine drops. He says straight after he goes to the toilet, about 5 or 10 mins after, he has some trouble with few drops. Then it subsides. 

He usually uses tissue with his underwear for a few minutes after going to the bathroom in case any drops come out and then discards it a short while later. 

He's concerned with ihraam and how would he manage. 

What would be suggested? Is there an option to wear underwear and pay damm? Or is there any alternative.

Husband wanting to reconcile after sending divorce notices to his wife

Q: My maid has a situation. Her husband hit her and forced her out of the house two years ago. Then, two months ago, he sent her two divorce notices at the same and one notice saying that she is of bad character and he wants custody of the children. Now, five days ago he sent a third divorce notice. 

He signed the first two notices but didn't sign the third one. He said he did it because he wanted her to feel threatened and come back herself. 

After sending all three notices with the last one sent five days ago, now he wants to get back together. 

Is their Nikah still valid, or are they completely divorced now?
