that Anas bin Malik said: "We went with the Messenger of Allah from Al-Madinah to Makkah, and he prayed two Rak'ah." He said: "I said to Anas: 'How long did Messenger of Allah stay in Makkah?' He said: 'Ten (days).'"  

خَرَجْنَا مَعَ النَّبِيِّ ﷺ مِنَ الْمَدِينَةِ إِلَى مَكَّةَ فَصَلَّى رَكْعَتَيْنِ قَالَ قُلْتُ لأَنَسٍ كَمْ أَقَامَ رَسُولُ اللَّهِ ﷺ بِمَكَّةَ قَالَ عَشْرًا قَالَ وَفِي الْبَابِ عَنِ ابْنِ عَبَّاسٍ وَجَابِرٍ  

"The Messenger of Allah traveled on a journey and he prayed two Rak'ah for nineteen days." Ibn Abbas said: "So when we would stay somewhere for nineteen (days) we would pray two Rak'ah , and if we stayed longer than that we would complete the Salat."  

سَافَرَ رَسُولُ اللَّهِ ﷺ سَفَرًا فَصَلَّى تِسْعَةَ عَشَرَ يَوْمًا رَكْعَتَيْنِ رَكْعَتَيْنٍ قَالَ ابْنُ عَبَّاسٍ فَنَحْنُ نُصَلِّي فِيمَا بَيْنَنَا وَبَيْنَ تِسْعَ عَشْرَةَ رَكْعَتَيْنِ رَكْعَتَيْنِ فَإِذَا أَقَمْنَا أَكْثَرَ مِنْ ذَلِكَ صَلَّيْنَا أَرْبَعًا
