Giving zakat to relatives who are entitled to it is better than giving it to those who are not your relatives, because giving charity to relatives is both charity and upholding the ties of kinship.
The Prophet (peace and blessings of Allah be upon him) said: “Charity given to a poor person is charity, but charity given to a relative is two things, charity and upholding the ties of kinship.” (Al-Nasaai & Tirmidhi)
However, you are not allowed to give zakat to those whom you are responsible to take care of financially such as your children, parents, and wives.
