Assalamualaikum,
A woman has two children already. She is pregnant again and had a miscarriage 10 years ago. During her pregnancy and miscarriage she said (not exact words but by the best of knowledge), maybe those words were “Allah humay he kion day raha hay aulad, unn ko kion nahi deta jo falana bayaulad hay” tou kiya yeh kufriya sentence hay? If yes then what that woman do for tauba? Are these kind of kufriya sentences may lead it to break the Nikah? If yes then how to do re-Nikah?
الجواب وباللہ التوفیق
The related sentence is absolutely not correct. One should make repentance and seek forgiveness for saying it and be particular in giving Sadaqah, however, it did not affect the Eemaan and Nikah, therefore, and there is no need for their renewal.
واللہ اعلم بالصواب
