حَدَّثَنَا أَبُو عُثْمَانَ سَعِيدُ بْنُ عَبْدِ الْجَبَّارِ الْبَصْرِىُّ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ ثَابِتٍ الْبُنَانِىِّ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « إِنَّ فِى الْجَنَّةِ لَسُوقًا يَأْتُونَهَا كُلَّ جُمُعَةٍ فَتَهُبُّ رِيحُ الشَّمَالِ فَتَحْثُو فِى وُجُوهِهِمْ وَثِيَابِهِمْ فَيَزْدَادُونَ حُسْنًا وَجَمَالاً فَيَرْجِعُونَ إِلَى أَهْلِيهِمْ وَقَدِ ازْدَادُوا حُسْنًا وَجَمَالاً فَيَقُولُ لَهُمْ أَهْلُوهُمْ وَاللَّهِ لَقَدِ ازْدَدْتُمْ بَعْدَنَا حُسْنًا وَجَمَالاً. فَيَقُولُونَ وَأَنْتُمْ وَاللَّهِ لَقَدِ ازْدَدْتُمْ بَعْدَنَا حُسْنًا وَجَمَالاً ».

It was narrated from Anas bin Malik that the Messenger of Allah (s.a.w) said: "In Paradise there is a market to which they will come every Friday. Then the north wind will blow and will blow on their faces and garments, and increase them in beauty and elegance. Then they will return to their families having increased in beauty and elegance and their families will say to them: 'By Allah, you have increased in beauty and elegance,' and they will say: 'By Allah, you too have increased in beauty and elegance."'
