باب مَا ذَكَرَ النَّبِيُّ صلى الله عليه وسلم وَحَضَّ عَلَى اتِّفَاقِ أَهْلِ الْعِلْمِ
Sahih al-Bukhari 7342

Narrated Abu Burda:

When I arrived at Medina, `Abdullah bin Salam met me and said to me, "Accompany me to my house so that I may make you drink from a bowl from which Allah's Messenger (ﷺ) used to drink, and that you may offer prayer in the mosque in which the Prophet (ﷺ) used to pray." I accompanied him, and he made me drink Sawiq and gave me dates to eat, and then I prayed in his mosque.

حَدَّثَنِي أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو أُسَامَةَ، حَدَّثَنَا بُرَيْدٌ، عَنْ أَبِي بُرْدَةَ، قَالَ قَدِمْتُ الْمَدِينَةَ فَلَقِيَنِي عَبْدُ اللَّهِ بْنُ سَلاَمٍ فَقَالَ لِي انْطَلِقْ إِلَى الْمَنْزِلِ فَأَسْقِيَكَ فِي قَدَحٍ شَرِبَ فِيهِ رَسُولُ اللَّهِ صلى الله عليه وسلم، وَتُصَلِّي فِي مَسْجِدٍ صَلَّى فِيهِ النَّبِيُّ صلى الله عليه وسلم‏.‏ فَانْطَلَقْتُ مَعَهُ، فَسَقَانِي سَوِيقًا، وَأَطْعَمَنِي تَمْرًا، وَصَلَّيْتُ فِي مَسْجِدِهِ‏.‏
