Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said: O Messenger of Allah! What is your view regarding the deeds we do: are they regarding something that has already been settled, or regarding something newly arising? The Prophet (peace and blessings be upon him) said: Rather, they are regarding something that has already been settled. He said: Then why will deeds be done? The Prophet (peace and blessings be upon him) said: For each one, that for which he was created is made easy.
Al-Bazzar recorded it, and its narrators are the narrators of the Sahih.
