Tawaf al-Nisa'
Tawāf al-nisāʾ (طواف النساء) is a tawaf and a two rak'a prayer which is one of the obligatory rites of hajj al-tamattu' and al-'umra al-mufrada. It is not obligatory in 'umra al-tamattu'. However, on the basis of caution, it is better to perform tawaf al-nisa' followed by its prayer with the hope of reward before taqsir.
However, if one wore ihram with the intention of al-'umra al-mufrada, after the taqsir or halq they should perform tawaf al-nisa' and its prayer and only after that their spouse will be halal for them.
The manner and rulings of tawaf al-nisa' and its prayer are similar to those of tawaf and prayer of tawaf.
Apparently, one should perform tawaf al-nisa' for al-'umra al-mufrada and hajj separately. For example, if a person performs two al-'umra al-mufradas or a hajj with an al-'umra al-mufrada, although it is not remote that one tawaf al-nisa' is sufficient to make the spouse halal for him, for the completion of rites he/she should perform two tawafs al-nisa' for two 'umras or for one 'umra or one hajj.
