حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، ح وَحَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا ابْنُ عُلَيَّةَ، - وَهَذَا لَفْظُهُ - أَخْبَرَنَا عَلِيُّ بْنُ زَيْدٍ، عَنْ أَبِي نَضْرَةَ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، قَالَ غَزَوْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَشَهِدْتُ مَعَهُ الْفَتْحَ فَأَقَامَ بِمَكَّةَ ثَمَانِيَ عَشْرَةَ لَيْلَةً لاَ يُصَلِّي إِلاَّ رَكْعَتَيْنِ وَيَقُولُ ‏"‏ يَا أَهْلَ الْبَلَدِ صَلُّوا أَرْبَعًا فَإِنَّا قَوْمٌ سَفْرٌ ‏"‏ ‏.‏

Narrated Abdullah ibn Abbas

The Messenger of Allah (ﷺ) had a stop of seventeen days in Mecca and he shortened the prayer (i.e. prayed two rak'ahs at each time of prayer). Ibn Abbas said: He who stays seventeen days should shorten the prayer; and who stays more than that should offer complete prayer.

Abu Dawud said: The other version transmitted by Ibn 'Abbas through a different chain adds: He (the Prophet) had a stop of nineteen days (in Mecca).
