Generally, everyone who is connected by lineage to the Holy Prophet Mohammad (pbuh), have nobility and honor (Every noble descent and kinship will be cut off on the day of resurrection, except my noble descent and kinship) and they are respectful for everyone.
Regarding to the great honor of the Holy Prophet’s descendant (pbuh) among the believers and the importance of observing Islamic laws related to “Sādat“?, such as the prohibition of receiving Zakat or the permission for receiving Khums, are those who are merely connected by lineage to the Sādāt dynasty on the father side?Or according to the position of the dearest daughter of Holy Prophet Mohammad (pbuh) in the Sādāt dynasty, those who are connected by lineage to this purified dynasty on the Mother side are also considered to be Sādāt? And, do the prohibition and Islamic laws of Sādāt include them? Does Sādāt pass on to the children of whom are deemed to be Sādāt on the mother side? And, do the Islamic laws and prohibition of Sādāt include them?
Ayatollah Safi Golpaygani
Generally, everyone who is connected by lineage to the Holy Prophet Mohammad (pbuh), have nobility and honor (Every noble descent and kinship will be cut off on the day of resurrection, except my noble descent and kinship) and they are respectful for everyone. They themselves also should preserve this noble lineage with religious and Islamic commitment.
However, those who are Sayyid on the mother’s side are privileged and honorable due to their lineage to the Holy Imams (pbuh), they do not deserve the specific Sadat’s Islamic laws such as Sadat’s Share and so on. These laws are related to those who are Sādāt on the father side. Whereas, in the present time the “Sayyid” title is a sign of being Sādāt on the father side and the rules of Sadat is considered as his/her right, so It is not permissible for the above mentioned persons to use this title and it has many consequences. And Allah is the all-Knowing.
They are deemed as the descendants of the Holy Prophet(pbuh), yet, they cannot wear the special Sadat clothes and they cannot benefit from the Sadat’s Share.
Ayatollah Makarem Shirazi
These people are Sayyid in some ways, and they are not in some other ways. They are not allowed to receive Khums and to use the special Sadat clothes, however, they have the honor of being Sayyid and also they are connected by lineage to Holy Prophet Mohammad (pbuh) and Her holiness Fatimah Zahra (pbuh).
Ayatollah Nouri Hamedani
Based on the assumption of the question that says their mother is Sayyida, they are respected too. But, they cannot use the title “Sayyid” before their first name, they cannot wear the special Sadat clothes. Moreover, they are not allowed to receive the Sadat’s share.
Ayatollah Shobiri Zanjani
The prohibition of receiving Zakat or the permission for receiving Khums is related to the Hashimi. Hashimi is someone who is connected by lineage to Hashim ibn Abd al-Manaf (the Prophet’s great grandfather (pbuh)).Sādāt refers to the descendant of Her Holiness Fatimah al-Zahra (pbuh) because they are connected by lineage to Hazrat Hashim (pbuh) through His Holiness Imam Ali (pbuh) and these Islamic Laws include them. However, those who are related to this dynasty are respected, they cannot be considered as Hashemi or Sayyid.
The Sādāt who are prohibited of receiving Zakat and are allowed to receive the Sadat’s Share with its terms is just dedicated for those who are connected by lineage to Hazrat Hashim ibn Abd Manaf on the father side. The connection on the mother side has no effect. They are merely the children of a Sādāt mother.
Ayatollah Mousavi Ardebili
Although a lineage through mother to infallible and purified household of the Holy Prophet Mohammad (pbuh) bring about glory and honor. But, the specific Sayyid and Hashemi Islamic laws are just applied for someone who is connected to that purified dynasty on the father side and the lineage does not transfer through mother.
It is intended by Sādāt and Bani Hāshim as those who are connected by lineage to Hashim on the father side and a lineage on the mother side is not valid.
Ayatollah Javadi Amoli
If only the father is Sayyid, there is no superiority of being man or woman. It is clear that his/her children, both boy and girl, are Sādāt and the Jurisprudential laws of Sādāt are applied for them.That means they can receive Khums, while Zakat is prohibited for them, unless, Sadat’s Zakat.But if the woman is Sayyida, these laws do not applied for her children, both boy and girl. This is merely a Jurisprudential law which is dedicated to Khums and Zakat. In other words, they cannot use the same financial source and they should use another source.
The descendant of Holy Prophet Mohammad (PBUH)
Zakāt is a financial obligation in Islam based on which Muslims have to pay a certain amount of nine items to be spent for the poor and for other social purposes.
In Islamic tradition, khums refers to the required religious obligation of any Muslim to pay one-fifth of their acquired wealth from certain sources toward specified causes.
