It is recorded in a hadith Prophet Muhammad (upon him and them blessings and peace): “I swear by the one who holds my soul in His Hand that these people cannot be believers unless they love you (Abbas (may Allah be pleased with him) uncle of Prophet (may Allah’s peace and blessings be upon him)) and my relatives.” (Tirmidhi).
However, we cannot give any charity (zakah, sadaqah, etc.) to this blessed household and their descendants, as this is not befitting for them. We could present gifts to the members of the family as a mark of respect, honour and love. As the Hadith below clearly states:
‘The (charities) are not permissible for Prophet Muhammad (may Allah’s peace and blessings be upon him) nor for the family of Muhammad (may Allah’s peace and blessings be upon him)’. (Malik Muwatta’).
