بسم الله الرحمن الرحيم
The Prophet (ﷺ) said:
يَوْمُ الْجُمُعَةِ ثِنْتَا عَشْرَةَ يُرِيدُ سَاعَةً لاَ يُوجَدُ مُسْلِمٌ يَسْأَلُ اللَّهَ عَزَّ وَجَلَّ شَيْئًا إِلاَّ آتَاهُ اللَّهُ عَزَّ وَجَلَّ فَالْتَمِسُوهَا آخِرَ سَاعَةٍ بَعْدَ الْعَصْرِ
Friday consists of twelve (hours). Amongst them there is an hour in which a Muslim does not ask Allāh for anything except that Allāh gives it to him. So seek it in the last hour after ‘Asr. (Abū Dawūd 1048. Declared Sahīh by Al-Albānī)
وروى سعيد بن منصور بإسناد صحيح إلى أبي سلمة بن عبد الرحمن أن ناسا من الصحابة اجتمعوا فتذاكروا ساعة الجمعة ثم افترقوا فلم يختلفوا أنها آخر ساعة من يوم الجمعة
Sa’ìd ibn Mansūr reported via an authentic chain of transmission up to Abū Salamah ibn ‘Abdur-Rahmān that a group of the companions of the Prophet (ﷺ) gathered and discussed regarding the hour that is on Jumu’ah. When they dispersed, they did so after agreeing that it was the last hour of Jumu’ah (after ‘Asr). (Fath al-Bārī of Ibn Hajr 2/483, Zād al-Ma’ād of Ibn al-Qayyim 1/379).
Al-Albānī said: The companions (of the Prophet (ﷺ)) agreed that (the hour) is during the last hour (after ‘Asr) during Jumm’uah, therefore it is not permitted to contradict them. (Sahīh Targhīb wa Tarhīb 1/441).
