Jamiat Tirmidhi: Hadith 502

I heard Ahmad bin Husain saying: "We were with Ahmad bin Hanbal, so they mentioned the one upon whom the Friday prayer is obligatory. Ahmad did not mention anything about it from the Prophet." Ahmad bin Al-Hasan said: "I said to Ahmad bin Hanbal: 'There is something about it from Abu Hurairah, from the Prophet.' So Ahmad bin Hanbal said: 'From the Prophet?' I said: 'Yes.'" [Ahmed bin Hanbal said:] "Hajjaj bin Nusair narrated to us; Mubarik bin Abbad narrated to us from Abdullah bin Sa'eed Al-Maqburi, from his father, from Abu Hurairah that the Prophet said: "The Friday prayer is required from whomever can return to his family by the night." He said: "So Ahmad [bin Hanbal] became angry with me, and he said to me: 'Seek forgiveness from your Lord, seek forgiveness from your Lord.'"
