Prayer is the second pillar of Islam. The 'Asr prayer has a great merit. Hence, the Messenger of Allah (may Allah's peace and blessings be upon him) urges Muslims to observe it. In this Hadīth, Abu Basrah al-Ghifāri (may Allah be pleased with him) reports that the Prophet (may Allah's peace and blessings be upon him) led some of his Companions in the ‘Asr prayer at Al-Mukhammas, which is the name of a path in Mount ‘Ayr on the way to Makkah. Then, he informed them that the 'Asr prayer was enjoined upon the preceding nations, but they did not observe it properly, not performing it in its due time, taking it lightly, and abandoning it. Then, Allah gave it to the Ummah of Islam, "so, whoever observes it will have his reward doubled"; the first reward is for observing it, unlike those who neglected it, and the second is a recompense for his deed like the rest of prayers. The Prophet (may Allah's peace and blessings be upon him) then forbade them from offering any supererogatory prayer until the sun sets and the "Shāhid", which is the star, appears. It was called "Shāhid" (witness) because it appears and is present at night and because a star does not appear and is not seen except after sunset. This does not contradict the confirmed texts that the Prophet (may Allah's peace and blessings be upon him) prayed Maghrib by sunset, as mentioned in the Two Sahīh Collections and others. This is a prohibition of prayer at sunset because it was when those who worshipped the sun used to pray. The word "after" here is not meant in a general sense; rather, it is meant to refer to the time of sunset and what is close to it. It is said that the prohibition of prayer during this time is only meant to prohibit delaying the obligatory prayer without a valid excuse until it is performed close to sunset. This prohibition does not include performing obligatory prayers or making up for missed prayers; it is exclusive to the supererogatory prayer. The Hadīth encourages the observance of prayer. It also encourages the observance of prayers in their due time. It clarifies the merit of this Ummah as it carefully maintains a prayer that was not maintained by the preceding nations. It also points out that the reward of whoever observes the ‘Asr prayer is doubled..
