He went to Mashhad in 186 (A.H.) and lived there for seven years. While he was there he attended the classes and participated in different scientific sessions as well as learning philosophy from Mirza Mehdi Shahid Khorasani. His teacher, because of his extensive knowledge, called him Baḥr al-ʿUlūm (ocean of knowledge ).

General religious leadership
His moral courage and spirit of reconciliation between Muslims was the cause of his collaboration with the great contemporary scholars on the performing of social duties. Some of his social activities are mentioned in the following: - He guided people to follow Sheykh Jafar Najafi in the affairs regarding jurisprudence. - He introduced Sheykh Muh yedin to perform judgement as a judge. - He announced the appointment of pious scholar and the congregational prayer leader of Hindi mosque as the leadership of the congregational prayer. - He encouraged his student Seyyed Javad Amuli –-the author of the Miftahul Kirama—to compile the books including the writing his own teachings which was based on the book of al-Wafi written by Feyz Kashani. - Allameh Baḥr al-ʿUlūm himself managed the people’s affairs as well as teaching jurisprudence and Hadith. Bahr-al-Ulum was not severe in his daily life and his generosity and loftiness of purpose was proverbial, so some scholars said that he had mystic tendencies. The effect of this tendencies would not be denied in some of his students and the scholars after his death. All of the contemporary scholars accepted that he had a great knowledge and piety, so Vahid Behbahani, as his teacher because of possibility of lacking the ability of Ijtahad in the last years of his life, asked him to express his opinion in jurisprudential problems. It is repeatedly stated that he had visited the Imam al-Zaman (a). It is worth mentioning that not only contemporary scholars but also latter day religious scholars did not deny this event. Baḥr al-ʿUlūm's biographers report that he was favoured by miraculous communication with the Prophet and the imams, especially the Twelfth Imam. It is repeatedly stated that he had visited the Imam al-Zaman Mehdi (a). Not only his contemporary scientists accepted this event but also the latter-day scholars confirmed it.
