alright..all these people who are suggesting the nikah to the same man who divorced her are completely wrong! She can't remarry the same man unless there's a halala, which means, she has to marry someone and IF she is divorced by that someone, only then she can remarry the first ex-husband. Tajdeed e nikah happens when husband gives two talaqs, and not all three. Someone with better knowledge can correct me or shed some more light on this.

You are right. Its what has been suggested to her too.. I forgot to mention the halala part.
