foetus

Q: As we recite the Holy Quraan and we see in Surat e Luqman that some kind of knowledge is with Allah and no one knows about that. For example when will it rain and what is inside of the women, either male or female and when and where will the person die. So nowadays we see the technology that every one knows that what is inside a female's abdomen. So is there controversial that the new tafseer will change from the old one and what answer will we give to non muslims when we explain these ayaats.

Q: Foreign countries offer cremation and sacking of the misscarried fetus. My aunt was 5 weeks pregnant and miscarried and not well at that time chose cremation for the fetus. Is that right or not. If not what can be done to make up for it.
