Sahih Bukhari | Volume 1 | Hadith Number 542

Narrated by Abu Musa
My companions, who came with me in the boat and I landed at a place called Baqi Buthan. The Prophet was in Medina at that time. One of us used to go to the Prophet by turns every night at the time of the Isha prayer. Once I along with my companions went to the Prophet and he was busy in some of his affairs, so the 'Isha prayer was delayed to the middle of the night He then came out and led the people (in prayer). After finishing from the prayer, he addressed the people present there saying, "Be patient! Don't go away. Have the glad tiding. It is from the blessing of Allah upon you that none amongst mankind has prayed at this time save you." Or said, "None except you has prayed at this time." Abu Muisa added, 'So we returned happily after what we heard from Allah's Apostle."
