Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) said: I stayed at Baqi’ Bathan with those of my companions who had come with me (from Abyssinia) by boat, at that time the Prophet Muhammad (peace and blessings be upon him) was residing in Madinah. Among us, someone would be appointed daily by turn to attend the ‘Isha prayer in the service of the Prophet (peace and blessings be upon him). By chance, once I and one of my companions went to the Prophet (peace and blessings be upon him). He was engaged in some work (he and Sayyiduna Abu Bakr Siddiq, may Allah be pleased with him, were discussing some public matter), due to which the prayer was delayed and about half the night had passed. Then the Prophet (peace and blessings be upon him) came and led the prayer. When the prayer was completed, he said to those present: Remain seated in your places with dignity and listen to a glad tiding. There is no one in the world at this time, except you, who is performing prayer, or he (peace and blessings be upon him) said: No (community) other than you has performed prayer at this time. Sayyiduna Abu Musa said: So we returned very happy after hearing this from the Prophet (peace and blessings be upon him).
