It is narrated from Sayyiduna Abu Musa Ash’ari (may Allah be pleased with him), he says: We performed the Maghrib prayer with the Messenger of Allah (peace and blessings be upon him), after which we thought that we should wait and perform the ‘Isha prayer with him as well. So we waited. When the Prophet (peace and blessings be upon him) came at the time of ‘Isha, he said:“Have you been sitting here since Maghrib?”We said:“O Messenger of Allah! Yes, we thought that we would perform the ‘Isha prayer with you as well.”The Prophet (peace and blessings be upon him) said:“You did well.”After that, the Prophet (peace and blessings be upon him) raised his head towards the sky, and he would often raise his head towards the sky, then he said:“These stars are the protectors of the sky; when they disappear, what Allah has promised for the sky will be fulfilled. And I am the protector of my companions; when I depart, what has been promised to my companions will befall them. And my companions are the protectors of my Ummah; when my companions depart, then severe conditions that have been promised to my Ummah will befall them.”
