Q 1: My mother had two children but they died at a young age and no `Aqiqah (sacrifice for a newborn) has been done on their behalf until now. This is because my father did not have enough money to pay for the `Aqiqah.
Bearing in mind that my father has already passed away, is it permissible for my mother to offer `Aqiqah on behalf of her children who passed away?
If the reality is exactly as what is mentioned in the question, it is permissible for your mother to offer `Aqiqah on behalf of the two children. She will be rewarded for this In Sha’a-Allah.
