Ayatollah Alozma Jannaati was born in Shahrud in the year 1311 A.H. (1932 A.D.). He was 6 years of age when his noble father sent him to school to learn the Qoran and Farsi literature. At 11 he entered the religious seminary of Shahrud where he finished preliminary levels as well as part of the graduate level (known as Sat-h) within four years. He was in his 18 when he finished the higher levels of Jurisprudence and Osul (principles) along with Sabzevaari's 'Sharhe Manzume' (Commentary on a Philosophical Poem) whereupon he migrated to Mashhad and benefited profusely from teachers of the city's religious Seminary.

After sometimes, He traveled to Qom where he attended Khaarej lectures on Jurisprudence and Osul (Principles) given, respectively by Ayatollah Brujerdi and Ayatollah Khomeyni.
