Does the meaning of the Hadith: "Every lineage and kinship will be severed on the Day of Resurrection, except for my lineage and kinship," include the relatives of the Prophet, peace and blessings be upon him, through suckling and marriage, such as foster parents, the husband of a sharifah, and his parents and siblings?

The meanings of the term "lineage" mentioned in the question can be summarized as follows:

1. The affiliation of the nation of Prophet Muhammad (peace be upon him) to him on the Day of Resurrection, whereas other nations will not be affiliated with their messengers. 2. Benefiting from the affiliation with him on the Day of Resurrection, unlike all other lineages from which no benefit will be gained. 3. Every cause and lineage will be severed on the Day of Resurrection except for his cause, lineage, and in-laws (peace be upon him). Here, "cause" refers to connection and affection, possibly through marriage, and "lineage" through birth.

Scholars have not mentioned that this favor includes those affiliated with him (peace be upon him) through fosterage, nor the parents of his in-laws.
