There is an interesting story how Sayyid Razi and his elder brother ‘Ali Abual-Kasim Sayyid Murtaza started their formal Islamic education.
Sheik Mufeed saw Hazrat Fatima Zehra and Hasnain (a.s) in his dream when she asked him to instruct her two small sons in Fiqh. Next morning, Fatima binte Hussain, the spouse of the Naqeeb (Herald) of Islam of the time holding the fingers of her two little sons and uttered only one sentence, Ilm huma al Fiqh, teach them Fiqh!
As he heard these words Sheik Mufeed’s eyes watered. Fatima binte Hussain, who descended from the 4th Imam (a.s), asked in surprise, “Why are you crying? I have requested you to instruct my sons on Fiqh and your eyes have watered.”
The Sheik only said, “I had seen a dream last night!” and then he recounted his dream. He had realized that on the two children the attention of Hazrat Fatima Zehra (a.s) was focused. Sheik Mufeed took the little children under his tutelage and instructed them with such dedication that Sayed Murtada and Sayed Radi achieved great heights in learning.
Sayed Radi in his short life of 47 years compiled the monumental work of the sermons and sayings of Hazrat Amir al Momineen (a.s) under the name and title of Nahj al Balagha— The Peak of Eloquence. This book has engaged the attention of the researchers and students for centuries. The book has been given the sobriquet of Akhu al Koran or the Brother of the Quran. Some detractors have observed that Syed Radi had himself written the contents of the compilation and had said that it was the work of Hazrat Ali (a.s). Although one would read a befitting reply to this contention in the preface of every translation of Nahj al Balagha, but I might only say here that the guage of the learning of Sayed Radi is that he worked to collect and compile the sayings and the sermons of Amir al Momineen (a.s). How great will be the caliber of learning of Sayed Radi that the scholars were attributing the highly eloquent writing to him! Syed Radi had penned another book and the style is entirely different from the contents of Nahj al Balagha.
Sayyid Murtaza, who acquired the epithet of ‘Alam al-Huda, was four years older than his brother and died at the age of 81 years in 436/ 1044. He served as Naqib al-Nuqaba’ after the death of Sayyid Razi and was considered a master of kalam, fiqh, usul al- fiqh, literature, grammar, poetry and other fields of knowledge. His divan or poetical composition runs into more than 20,000 verses. He authored several books such as al-Shafi fl al-Imamah, al- Dhakh’irah fi Usul al-Fiqh, al-Ghurar wa al-Durar, and al-Tanzih.
