Sahih al-Bukhari 6127
Narrated Al-Azraq bin Qais:
We were in the city of Al-Ahwaz on the bank of a river which had dried up. Then Abu Barza Al- 
Aslami came riding a horse and he started praying and let his horse loose. The horse ran away, so Abu 
Barza interrupted his prayer and went after the horse till he caught it and brought it, and then he 
offered his prayer. There was a man amongst us who was (from the Khawari) having a different 
opinion. He came saying. "Look at this old man! He left his prayer because of a horse." On that Abu 
Barza came to us and said, "Since the time I left Allah's Messenger (ﷺ), nobody has admonished me; My 
house is very far from this place, and if I had carried on praying and left my horse, I could not have 
reached my house till night." Then Abu Barza mentioned that he had been in the company of the 
Prophet, and that he had seen his leniency.
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنِ الأَزْرَقِ بْنِ قَيْسٍ، قَالَ كُنَّا عَلَى شَاطِئِ نَهْرٍ بِالأَهْوَازِ قَدْ نَضَبَ عَنْهُ الْمَاءُ، فَجَاءَ أَبُو بَرْزَةَ الأَسْلَمِيُّ عَلَى فَرَسٍ، فَصَلَّى وَخَلَّى فَرَسَهُ، فَانْطَلَقَتِ الْفَرَسُ، فَتَرَكَ صَلاَتَهُ وَتَبِعَهَا حَتَّى أَدْرَكَهَا، فَأَخَذَهَا ثُمَّ جَاءَ فَقَضَى صَلاَتَهُ، وَفِينَا رَجُلٌ لَهُ رَأْىٌ، فَأَقْبَلَ يَقُولُ انْظُرُوا إِلَى هَذَا الشَّيْخِ تَرَكَ صَلاَتَهُ مِنْ أَجْلِ فَرَسٍ‏.‏ فَأَقْبَلَ فَقَالَ مَا عَنَّفَنِي أَحَدٌ مُنْذُ فَارَقْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَقَالَ إِنَّ مَنْزِلِي مُتَرَاخٍ فَلَوْ صَلَّيْتُ وَتَرَكْتُ لَمْ آتِ أَهْلِي إِلَى اللَّيْلِ‏.‏ وَذَكَرَ أَنَّهُ صَحِبَ النَّبِيَّ صلى الله عليه وسلم فَرَأَى مِنْ تَيْسِيرِهِ‏.‏
