The Meaning of a Righteous Child and Ongoing Charity in the Hadith on the Cessation of Deeds

Question:
The questioner: Regarding the hadith of the Messenger , the question is: Is the intended meaning of a righteous child the male, excluding the female? And can a grandchild, whether male or female, take the place of a righteous child? And is the intended meaning of ongoing charity only building mosques? Or is it comprehensive? May Allah reward you with good.

Answer:
The Shaykh: By a righteous child, the offspring from males and children are meant, whether they are the children of the Shaykh, the children of the sons, or the children of the children, however far down the line they go; they are all considered children. The Prophet (peace and blessings be upon him) said to al-Hasan ibn 'Ali ibn Fatimah (may Allah be pleased with her), "This son of mine is good," even though he was the son of his daughter (peace and blessings be upon him). So the children of the children are considered children of the person, and they are included in the saying of the Messenger (peace and blessings be upon him), "or a righteous child who prays for him," whether they are from his direct line or from the children of his children, however far down the line they go, the children of the children, and the children of the daughters. The children of the children, male and female, the children of the children. If the intended meaning were males, we would say "sons." When we say "children," it includes males and females. For this reason, Allah the Exalted said: , so the term "children" includes males and females. As for ongoing charity, the scholars have mentioned that the intended meaning is the time, whether it is a mosque, a ribat, a house in which the needy reside, or something similar. The intended meaning is the time; ongoing charity means that which continues, unlike the interrupted charity which is cut off. The reproductive charity is that which continues after the death of the one who gave it. Yes. May Allah reward you with good, and may He do you good.
