One of the heirs taking more than his stipulated share of the inheritance

Q: I want to know that a man who was in a government job dies (he has two sons and two daughters). Elder son gets job in his fathers place and gets well settled. Younger son did everything on his own but still not settled. In the light of Islam, should he get some extra benefit as the elder one got a government job? They have a paternal house on their mothers name who is alive.

Aqeeqa

Q: Aqeeqa should be done by parents. If parents are poor and husband wants to do wife's aqeeqa, is he allowed to do so? A wife whose aqeeqa has been done by husband is she allowed to eat or keep that meat for herself? What will be the procedure of her aqeeqah? Is it a must for her to shave her hair completely? Please answer as soon as possible. Can you answer according to Imam Shafi?
