according to iran's religious leader and the deobandi creed, which is a creed especially followed by patriarchal pashtun tribes, the status of being a sayyid can only be attributed through the patrilineal lineage. according to shia opinions, children of a sayyida mother and a non-sayyid father are referred to as mirza. the persian notation "mirza", which is a derivation of the word "mirzada" i.e. son of a "mir" has various meanings. one of the meanings of "mir" is a sayyid leader of a sayyid branch or community, simultaneously being a religious islamic scholar. thus, a sayyid of patrilineal lineage, being the son of a mir can also be called "mirza". this example substantiates the fact that there are different opinions concerning the transmission of the title "sayyid". another historical opinion of ottoman naqib al ashrafs expresses that children of maternal prophetical descent are called "sharif".
