A friend of mine is about to get married to lady who has 4 children from previous marriages. She has put some conditions...is this marriage valid??

In principle, to stipulate conditions prior to the Nikah will be permissible%0D%0Aas long as the conditions comply with the Shari'ah. If such conditions are%0D%0Astipulated whereby there is abuse of the rights of any of the spouses, then%0D%0Asuch a condition is null and void.%0D%0A%0D%0AIn the abovementioned case, three conditions were stipulated. The second%0D%0Aconditions falls within the limits of the Shari'ah. Since it is the sole%0D%0Aresponsibility of the husband to fulfil the expenses of the wife, he alone%0D%0Ais responsible. However, in this case, the wife on her own is giving up her%0D%0Aright happily. If the husband agrees, there is nothing wrong. The first and%0D%0Athird condition is in reality one condition. It is the right of the husband%0D%0Ato spend the night with his wife. In this case, the husband has happily%0D%0Aagreed to forgo his right. Therefore, briefly the Nikah will be valid since%0D%0Aboth parties have happily agreed to these conditions and are prepared to%0D%0Aforgo their rights.
