In another Hadith Nabie mentioned: "When a lady prostrates, she must attach her stomach to her thighs, i.e. her stomach and thighs must touch each other. ("Sunanul Kubra", Vol.2, Page 223.)
Jazak Allah for this sis,
One part that I think needs to be addressed though is where it says not to touch the thighs to the belly. I've read a few hadiths that indicate this is for the males. But women are instructed to touch belly to legs to conceal and be modest.
May Allah forgive me if I am incorrect.
