His narration from Jabir (RA) has:

Allah's Messenger (RA) stayed at Tabuk for twenty days, and he shortened the prayers (during his stay). [Its narrators are reliable, except that there is difference about whether or not it is Mawsul (unbroken chain of narrators)].

وَلَهُ عَنْ جَابِرٍ: { أَقَامَ بِتَبُوكَ عِشْرِينَ يَوْمًا يَقْصُرُ اَلصَّلَاةَ } وَرُوَاتُهُ ثِقَاتٌ, إِلَّا أَنَّهُ اُخْتُلِفَ فِي وَصْلِه ِ [1]‏ .‏
