Women facing their toes towards the qiblah during sajdah?

Q: In salah I mistakely thought women were supposed to point both toes towards the qibla in sajdah because I felt like I remembered reading an instruction which said that. My feet were both on the ground horizontally, however the toes were towards the qibla. I’d like to believe my past prayers were ok? Are prayers ok even if women follow the man’s way?

The noble and polite character of Rasulullah (Sallallahu Alayhi Wasallam)

Q: I read somewhere that the Holy Prophet sallallahu alaihi wasallam at some occasions used harsh words to people. It was written that he would impugn then. Is the definition of impugn which is meant in the ahadith ‘to cause people to doubt someone's character, qualities, or reputation by criticizing them’. Also when we say harsh words, what was the manner of the Holy Prophet sallallahu alaihi wasallam in that case? Did he say the words in an angry tone?
