Anas reported God’s Messenger as saying, “Seek the time in which hope is placed on Friday from after the afternoon prayer till sunset." Tirmidhi transmitted it.

وَعَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْتَمِسُوا السَّاعَةَ الَّتِي تُرْجَى فِي وَيَوْم الْجُمُعَةِ بَعْدَ الْعَصْرِ إِلَى غَيْبُوبَةِ الشَّمْسِ» . رَوَاهُ التِّرْمِذِيّ
