Hadith 31-101

وَبِهذَا الإِسنادِ قالَ: قالَ عَلِىُّ بْنُ أَبِي طالِبٍ‏ عَلَيْهِ السَّلامُ: صلّى‏ بِنا رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَآلِهِ صَلاةَ السَّفَرِ، فَقَرَأَ فِي الأُوْلَى الجَحدَ وَفِي الثَّانِيَةَ التَّوحيدَ، ثُمَّ قالَ: قَرَأتُ لَكُمْ ثُلْثَ الْقُرْآنِ وَرُبعَهُ.

According to the same documentation, it is narrated that Ali ibn Abi Talib (a.s.) said, “God’s Prophet (S) prayed with us while we were on a journey and recited the Chapter ‘Al-Jahd in the first unit and the Chapter ‘Al-Tawhid in the second unit of the prayer and said, ‘I recited a third of the Quran and a fourth of the Qur’an for you.’”
