It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "That I pray the Fajr prayer, then sit in my place and remember Allah until the sun rises, is dearer to me than charging on swift horses in the path of Allah."
(Note on the chain:) Al-Dabari said "Ayyash" in this way, whereas the correct name is "Abbas".
