What is the authenticity of the hadith: “No Muslim raises his house higher than seven cubits”?

Question:
What is the authenticity of the hadith: ?

Answer:
This is not a hadith, and it is likely from the saying of some of the Salaf. However, it is established from the Prophet (peace and blessings be upon him) that he mentioned excessive height in building as one of the signs of the Hour. However, there is no prohibition of that from the Messenger (peace and blessings be upon him). Likewise, one of the signs of the Hour is that a slave woman will give birth to her mistress. The meaning of this is concubinage, such that the slave woman gives birth to her mistress, meaning her master. In another wording, it is said “her master” is named so because her son is her master in meaning. It is known that concubinage is permissible, even if its prevalence is one of the signs of the Hour, and that does not prevent it from being one of the signs of the Hour. The Prophet (peace and blessings be upon him) took his slave girl Maryam as a concubine, and she gave birth to his son Ibrahim. Likewise, the Companions (may Allah be pleased with them) took concubines, and likewise those after them from the righteous Salaf. And success is from Allah.
