Sahih al-Bukhari 905
Sahih al-Bukhari · Book 11: Friday Prayer · The time for the Jumu'ah (prayer) is due when the sun declines (i.e. just after mid-day)
Narrated Anas bin Malik:
حَدَّثَنَا عَبْدَانُ ، قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ ، قَالَ أَخْبَرَنَا حُمَيْدٌ ، عَنْ أَنَسٍ ، قَالَ كُنَّا نُبَكِّرُ بِالْجُمُعَةِ، وَنَقِيلُ بَعْدَ الْجُمُعَةِ.
We used to offer the Jumua prayer early and then have an afternoon nap.
