Al-Musnad of Imam Ahmad

Egyptian edition: 12 volumes. 100% harakat.
Each Hadith or Athar is annotated and its reference is given and its authenticity is discussed.
This edition was published from that of the great Egyptian Muhaddith Ahmad Chakir. We can, therefore, find his words on the degree of authenticity of the hadiths in the first four volumes, cause he didn't finish it. The work of Tahqiq is completed by several researchers in order to bring back the references of each hadith and the words of great imams on their authenticity (as al-Haythami, adh-Dhahabi, al-Hakim etc ...).
