Isma'il ibn 'Abd Allah ibn Khalid narrated to us, al-Walid ibn Muslim narrated to us, al-Awza'i narrated to us, from Yahya ibn Abi Kathir, Abu Salamah narrated to us, from Abu Hurayrah, from the Prophet, may Allah bless him and grant him peace, who said: "The people will stand for the Lord of the worlds for the duration of half a day of fifty thousand years. That day will be made easy for the believer, like the sun hanging low for sunset until it sets."
