Sahifat Hammam ibn Munabbih

 (صحيفة همام بن منبه), lit. 'The Book of Hammam ibn Munabbih', is a hadith collection compiled by the Yemeni Islamic scholar Hammam ibn Munabbih ( or 130 AH / 748 CE). It is sometimes quoted as one of the earliest surviving works of its kind.

The Sahifat exists in three somewhat variant recensions, one of which is in Ahmad ibn Hanbal's Musnad.

Discovery and publication
It is the oldest surviving collection of hadith, it exists in various manuscript collections and printed versions are widely available. The original manuscript for the text has been lost, but the text survives through secondary copies of it. It was first discovered and published in the 20th century by Muhammad Hamidullah. This publication was a collation of two manuscript copies of Sahifa Hammam ibn Munabbih, one found in a library in Damascus and the other in a library in Berlin. The collection contains 138 hadith.

Literature
R. Marston Speight has studied the variation in the wording between equivalent hadith found across the collections in the Sahifat, that of the Musnad of Ahmad ibn Hanbal, as well as Sahih al-Bukhari and Sahih Muslim.
