I fell ill and lbn 'Umar came to inquire after my health, and I asked him about the glorification of Allah (i. e. prayer) while travelling. Thereupon he said: I accompanied the Messenger of Allah ﷺ on a journey but I did not see him glorifying Him, and were I to glorify (Him). I would have completed the prayer. Allah, the Exalted, has said:" Verily there is a model pattern for you in the Messenger of Allah."
صَحِبْتُ رَسُولَ اللَّهِ ﷺ فِي السَّفَرِ فَمَا رَأَيْتُهُ يُسَبِّحُ وَلَوْ كُنْتُ مُسَبِّحًا لأَتْمَمْتُ وَقَدْ قَالَ اللَّهُ تَعَالَى { لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ إِسْوَةٌ حَسَنَةٌ}
