Sahih Muslim Book - 7, Hadith - 2042

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ حَدَّثَنَا غُنْدَرٌ عَنِ ابْنِ جُرَيْجٍ قَالَ أَخْبَرَنِى عُمَرُ بْنُ عَطَاءِ بْنِ أَبِى الْخُوَارِ أَنَّ نَافِعَ بْنَ جُبَيْرٍ أَرْسَلَهُ إِلَى السَّائِبِ ابْنِ أُخْتِ نَمِرٍ يَسْأَلُهُ عَنْ شَىْءٍ رَآهُ مِنْهُ مُعَاوِيَةُ فِى الصَّلاَةِ فَقَالَ نَعَمْ. صَلَّيْتُ مَعَهُ الْجُمُعَةَ فِى الْمَقْصُورَةِ فَلَمَّا سَلَّمَ الإِمَامُ قُمْتُ فِى مَقَامِى فَصَلَّيْتُ فَلَمَّا دَخَلَ أَرْسَلَ إِلَىَّ فَقَالَ لاَ تَعُدْ لِمَا فَعَلْتَ إِذَا صَلَّيْتَ الْجُمُعَةَ فَلاَ تَصِلْهَا بِصَلاَةٍ حَتَّى تَكَلَّمَ أَوْ تَخْرُجَ فَإِنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- أَمَرَنَا بِذَلِكَ أَنْ لاَ تُوصَلَ صَلاَةٌ حَتَّى نَتَكَلَّمَ أَوْ نَخْرُجَ.

'Umar bin 'Ata' bin Abi Al-Khuwar narrated that Nafi' bin Jubair sent him to As-Sa'ib, the son of the sister of Namir, to ask him about something that Mu'awiyah had said concerning his prayer, and he said: "Yes, I prayed Jumu'ah with him in his enclosure, and when the Imam said the Salam, I stood up where I was and prayed. When he entered (his apartment) he sent for me and said: 'Do not repeat what you did. When you have prayed Jumu 'ah, do not offer another prayer after it until you have spoken or gone out, for the Messenger of Allah (s.a.w) enjoined that upon us, that we should not join one prayer to another until we had spoken or gone out."'
