Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him): He says, the Prophet (peace and blessings be upon him) was teaching the companions matters of religion when suddenly their eyes were raised upwards. The Prophet (peace and blessings be upon him) asked: "What is it that has caused your eyes to be raised upwards?" They said: We looked at the moon. The Prophet (peace and blessings be upon him) said: "What will your condition be at that time when you will see Allah the Exalted clearly?"
