We used to observe (Jumu'a) prayer with the Messenger of Allah ﷺ and then we returned and gave rest to our camels used for carrying water. Hassan[ (one of the narrators) said: I asked Ja'far what time that was. He said.. It is the time when the sun passes the meridian.
كُنَّا نُصَلِّي مَعَ رَسُولِ اللَّهِ ﷺ ثُمَّ نَرْجِعُ فَنُرِيحُ نَوَاضِحَنَا قَالَ حَسَنٌ فَقُلْتُ لِجَعْفَرٍ فِي أَىِّ سَاعَةٍ تِلْكَ قَالَ زَوَالَ الشَّمْسِ
