Musnad Imam Bin Hanbal

Allah, may He be glorified and exalted, chose from among His slaves the best of the scholars and gave them the honour of conveying the Prophet's (PBUH) sayings.

First and foremost among these upright scholars are the noble Companions (Sahabah), who learned the Revelation from the Messenger of Allah (PBUH) and then conveyed it precisely to those who came after them among the Followers (Tabi'een). Then the Tabi'een transmitted it to those who came after them, until there came the time of documentation when the Imams of hadiths compiled the books known as Jawami`, Masanid and Sunans.

One of the greatest compilations of the Sunnah and books of hadeeth is the Musnad by Imam Ahmad bin Hanbal, which is organised into compilations of the Hadiths narrated by each Companion (Sahabi), starting with the 'ashra mubashshara.
