It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once we were sitting with the Prophet (peace and blessings be upon him), after the Asr prayer, and the sun was still over Mount Qaiqan. The Prophet (peace and blessings be upon him) said: "In comparison to the lifespans of the previous nations, your lifespans are like this remaining part of the day, which is very little compared to the part that has already passed."
