Ahmad bin Salamah said: I heard Muslim bin al-Hajjaj (may Allah have mercy on him), when I discussed this hadith of Makhramah with him, say: "This is the best and most authentic hadith regarding the explanation of the hour of Friday."
The Shaykh said: It is in a hadith: "Seek this hour in the last hour after Asr."
