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 the pious people. 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.
