assalamualekum sir main ye janna chahta hun ke humare dharam me bachche na hone ke liye aurat agar operation kara le to kya uski namaaz nahi hoti maine aisa suna hai. please meri problem ka solution jaldi karen meharbani hogi.
The salah is valid if all the conditions of salah are fulfilled, but opting for operation in order to avoid more children without a valid reason and permanently terminating the reproduction ability is haram and unlawful in Islam. It is severe sin; a woman must not do it.
Allah (Subhana Wa Ta’ala) knows Best
