It is narrated from Sayyiduna Ibn Abi Awfa (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Those servants are favoured by Allah who watch the sun, the moon, the stars and the new moons for the remembrance of Allah."
Abd al-Jabbar bin al-Ala' is alone in narrating it with this chain in this way, and he is thiqah (trustworthy).
