6 shareholders distributing the 7th share of the qurbaani animal that was done for Nabi (sallallahu alaihi wasallam) equally

Q: If 6 shareholders put money together to make qurbani on behalf of Nabi صلى الله عليه وسلم with the 7th share of an animal, how will the meat of the 7th share be divided? Does it have to be shared equally between the 6 people same as the other 6 shares?

Aborting a baby due to deformation of the baby

Q: My sister was 6 months pregnant when a scan showed the baby was not growing well. The doctor said this is a case that the baby will not grow properly. The baby has no lungs and is just alive on the mothers breath. The doctor said if you wait for normal delivery there will be some risks in the delivery and also to the mother's health. The doctor advised to terminate the baby. And we accepted the advice. The baby was delivered and in a few hours died. Sometimes I feel it was not the right thing we done. Maybe if she delivered on her own time then the baby would be alive. 

What is the Islamic ruling? Was what we done a serious sin? If yes, is there a chance of Allah's forgiveness?

Woman making her salaah qadha due to delaying in checking if her haidh started

Q: I prayed zuhr after it had ended because I'm due to begin my period and earlier when I checked my discharge, it seemed somewhat dark but I still wasn't sure. So I kept checking until before asr. However, I delayed it too long and checked only a few minutes before asr was due to start before I decided I felt more inclined towards me not having started my menses as my discharge appeared repeatedly clear. I ended up doing wudu and praying zuhr after asr began (without doing ghusl). Am I sinful?
