[Machine] The Prophet ﷺ used to, when he stayed at a place, not depart from it until he offered two Rak'ahs (units of prayer) or bid farewell to the place by offering two Rak'ahs. Abdullah said: "Uthman bin Sa'd was weak."  

أَنَّ النَّبِيَّ ﷺ «كَانَ إِذَا نَزَلَ مَنْزِلًا لَمْ يَرْتَحِلْ مِنْهُ حَتَّى يُصَلِّيَ رَكْعَتَيْنِ أَوْ يُوَدِّعَ الْمَنْزِلَ بِرَكْعَتَيْنِ» قَالَ عَبْد اللَّهِ «عُثْمَانُ بْنُ سَعْدٍ ضَعِيفٌ»
