Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "For every group of people of a deed there is a particular door among the doors of Paradise, and they will be called from that door on account of that deed." After this he mentioned the complete hadith.
Ahmad recorded it; its narrators are the narrators of the Sahih, except Muhammad bin Amr bin Alqamah, and a group (of scholars) declared him trustworthy.
