updates on Mandi

Asked my friend last night on mandi wiladah. she looked it up into some of her fiqh kitab and found out that for mothers who gave birth and keluar nifas, mandi hadas besar once is enough. but utk yg give birth  (termasuk yg bersalin secara cesar) tp takde darah nifas keluar or keguguran, wajib mandi hadas besar juga..dan yg tu la yg dipanggil mandi wiladah. wallahua'lam.  she's going to ask some ustazah that she knows on this issue. so i'll update when she update :)
