Sahih al-Bukhari · Book 18: Shortening the Prayers (At-Taqseer) · Whoever did not offer the Nawafil before and after the (compulsory) Salat during a journey
Narrated Hafs bin `Asim:
حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ ، قَالَ حَدَّثَنِي ابْنُ وَهْبٍ ، قَالَ حَدَّثَنِي عُمَرُ بْنُ مُحَمَّدٍ ، أَنَّ حَفْصَ بْنَ عَاصِمٍ ، حَدَّثَهُ قَالَ سَافَرَ ابْنُ عُمَرَ ـ رضى الله عنهما ـ فَقَالَ صَحِبْتُ النَّبِيَّ صلى الله عليه وسلم فَلَمْ أَرَهُ يُسَبِّحُ فِي السَّفَرِ، وَقَالَ اللَّهُ جَلَّ ذِكْرُهُ {لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ} .
Ibn `Umar went on a journey and said, "I accompanied the Prophet (ﷺ) and he did not offer optional prayers during the journey, and Allah says: 'Verily! In Allah's Messenger (ﷺ) you have a good example to follow.' " (33.21)
