Hamza, 49, known in London as the "preacher of hate," is serving seven years in Belmarsh Prison for inciting the killing of non-Muslims, The Sunday Telegraph reported.
His wife, Nagat Mostafa, 46, claims her husband is the victim of racist bullying and medical neglect, the British newspaper reported.
In May, Hamza, a double-amputee who wears prosthetics on both hands, underwent additional surgery to remove an inch of infected bone from his left arm stump.
In a letter to al-Maqreze Center for Historical Studies, Mostafa blamed the bone infection on the harsh conditions of her husband's cell, and the lack of soft padding for his arms.
