Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrated that once there was a solar eclipse, so the Prophet stood up in great anxiety, fearing that perhaps the Hour (of Judgment) might be established. He went to the mosque and performed a prayer with very long standing, long bowing, and long prostrations; I had never seen him perform like that before. After the prayer, he said that these are signs which Allah sends; they do not occur because of anyone's death or life, but rather Allah sends them to frighten His servants. Therefore, when you see anything like this, immediately hasten towards the remembrance of Allah and seeking forgiveness.
