Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
Are the additions at the end of the Ratib of Imam al-Haddad part of it?
The additions were added by later scholars. They originate from narrations of the Prophet ﷺ. There were originally three fatihahs at the end of the Ratib: the first for al-Faqih al-Muqaddam, the second for the Ba ‘Alawi shaykhs and the Sufis wherever they may be and the third for the Ummah. The rest were added by various scholars.
