Equality towards Children

Q: Would a father be sinful for giving some of his children more money than others - for example financing the trip of one child to go abroad but not giving any money to the other child? Another situation might be the father giving one child thousands of pounds for their studies and giving nothing to the other child. Or does Shari'ah allow a father to give one of his children more money than others (whilst the father is still well and alive)?
