Prayer is the greatest practical pillar of Islam after the twin declaration of faith (shahadatayn), and is of specific importance in Islamic teachings. Allah (may He be exalted) has ordained certain times at which prayer is to be offered, and whoever misses that time must make up the prayer, and not neglect it. In this hadith, Abu Qatadah al-Ansari (may Allah be pleased with him) narrates that the Sahabah (may Allah be pleased with them) were with the Messenger of Allah (blessings and peace of Allah be upon him) on a journey, and they said to him: Why don’t we stop at the end of the night, O Messenger of Allah, so that we can rest? He (blessings and peace of Allah be upon him) said: “I am afraid that you will sleep and miss the prayer” – referring to Fajr prayer. This indicates that he (blessings and peace of Allah be upon him) wanted to keep travelling until the time of Fajr; that was because he was concerned about the prayer and wanted to give it precedence over sleep and rest. Then Bilal suggested to the Prophet (blessings and peace of Allah be upon him): I will wake you up – meaning that he (may Allah be pleased with him) would stay awake until the time for Fajr began, so that he could wake them up. So they lay down and went to sleep, which indicates that the Messenger of Allah (blessings and peace of Allah be upon him) accepted Bilal’s suggestion. Or Bilal said to them: Go and lie down. Bilal rested his back against his mount, then he fell asleep too. The Prophet (blessings and peace of Allah be upon him) woke up when the sun had started to peek over the horizon, which indicates that they had slept until the time for Fajr prayer had ended. The Prophet (blessings and peace of Allah be upon him) rebuked Bilal by saying, “What about what you said?” In other words, what about your promise to wake us up when the time for prayer came? Bilal said: I have never been so overwhelmed by the urge to sleep – meaning that he had never slept before as he did on this occasion. The Prophet (blessings and peace of Allah be upon him) said: “Allah took your souls when He willed, and returned them to you when He willed”; this was a confirmation of the word of Allah (may He be exalted): {Allah takes the souls at the time of their death, and those that do not die [He takes] during their sleep. Then He keeps those for which He has decreed death and releases the others for a specified term} [az-Zumar 39:42]. What is meant is that He takes their souls when they sleep, and returns them when they wake up. Then the Prophet (blessings and peace of Allah be upon him) instructed Bilal to give the call to prayer, and he did wudu’, then he stood up and led the people in praying Fajr, after the sun had risen and become clear. According to a report narrated by Muslim, the Prophet (blessings and peace of Allah be upon him) did not pray in the place where they had missed the prayer; rather they got on their mounts and rode on for a short distance, then they dismounted. Then the Prophet (blessings and peace of Allah be upon him) did wudu’ and made up the Fajr prayer. This hadith highlights some of the teachings of the Prophet (blessings and peace of Allah be upon him) in the event of sleeping or missing a prayer. It also indicates that it is prescribed to give the adhan and pray in congregation in the case of a missed prayer..
