Is zakat obligatory on money deposited in an investment certificate, and is previous zakat paid to the father counted?

What is given to the father is not counted as zakat, and it is not permissible to give zakat to parents unless the father is indebted for the benefit of the Muslims. What is given to the poor brother or the poor widow whose husband has passed away is counted as zakat, on the condition that the orphan and the widow are poor to be eligible for zakat. Savings for the future are subject to zakat, even if the intention is to spend them on oneself and one's family.
