How can one verify a person's lineage to the Prophet, peace and blessings be upon him?

To verify your lineage, ask experts and specialists in genealogy, especially if they are from the Ahl al-Bayt and in your country, for they know best. This is in accordance with the Almighty's saying: "So ask concerning it one well informed" and "None can inform you like one who is خبر (All-Aware)" and "So ask the people of the message if you do not know." You can also refer to books on genealogy. It should be noted that delving deeply into the science of genealogy beyond what is necessary to connect kinship ties is disliked, based on the saying of Umar, may Allah be pleased with him: "Learn enough of your genealogies to maintain your ties of kinship."
