Janabah

Dear scholars, As-Salamu `alaykum. I prayed Fajr, Zuhr and `Asr without having had a bath for janabah (impurity) because I forgot. After having a bath at Maghrib time I repeated these prayers before praying Maghrib. Then my husband told me that it is essential to have the correct intention before having a bath, so I had a bath and prayed `Isha’ and I did not repeat the rest of the prayers. Are my prayers from Fajr to Maghrib valid? What should I do? Jazakum Allah khayran.

Is it permissible for a woman to do her usual household duties such as cooking, looking after the children, and housework, before she performs ghusl (purifactory bath) following intercourse?

Respected scholars of Islam, As-Salaam `Alaykum wa Rahmatullah wa Barakatuh. Is it permitted to cut nails and hair before taking bath, while I’m in a state of Janabah? Thanks for your help.

I was told that you need to recite a dua'a during ghusl but wanted to learn what is the proper way of performing ghusl. Is there a special dua'a for it? If so, what is it?
