Musnad Abi Ya'la 7276 — he said: We prayed Maghrib with the Messenger

It is narrated from Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) that he said: We prayed Maghrib with the Messenger of Allah (peace and blessings be upon him), then we said (among ourselves): If only we stayed sitting here until we also pray Isha with him (peace and blessings be upon him) (how good that would be). He said: So we sat there. Then he (peace and blessings be upon him) came out to us and asked: "Are you still here?" We said: Yes, O Messenger of Allah! We prayed Maghrib with you, then we thought we would keep sitting until we also pray Isha with you. He (peace and blessings be upon him) said: "You have done very well," or he said: "You have done right." Sayyiduna Abu Musa (may Allah be pleased with him) said: Then he (peace and blessings be upon him) raised his blessed head towards the sky, and he (peace and blessings be upon him) often used to raise his blessed head towards the sky, and said: "The stars are a safeguard for the inhabitants of the heavens; so when the stars disappear, there will come upon the inhabitants of the heavens the terror that they have been promised. And I am a guarantor of safety for my Companions; so when I depart (from this world), there will come upon my Companions the trials that they have been promised. And my Companions are a safeguard for my Ummah; so when my Companions depart, there will come upon my Ummah the tribulations that they have been promised."
