Assalamualaikum
If one has a shower with the intention of becoming paak for namaaz, then does one still have to make wudhu as well – if all parts of the body became wet with water.
If a woman has a body shower (hair not washed) with the intention of becoming paak for namaaz, then makes masaah of her head and gargles her mouth and cleans her nostrils, does she become paak for wudhu.
Jazakallah
