"We asked Salim bin 'Abdullah about prayer while traveling. We said: 'Did 'Abdullah combine any of his prayer while traveling?' He said: 'No, except at Jam'.'[1] Then he paused, and said: 'Safiyyah was married to him, and she sent word to him that she was in her last day in this world and the first day in the Hereafter. So he ride off in a hurry, and I was with him. The time for prayer came and the Mu'adhdhin said to him: 'The prayer, O Abu 'Abdur-Rahman! But he kept going until it was between the time for the two prayer. Then he stopped and said to the Mu'adhdhin: "Say the Iqamah, and when I say the Taslim at the end of Zuhr, say the Iqamah (again) straight away." So he said the Iqamah and he prayed Zuhr, two Rak'ahs, then he said the Iqamah (again) straight away, and he prayed 'Asr, two Rak'ahs. Then he rode off quickly until the sun set and the Mu'adhdhin said to him: "The prayer, O Abu 'Abdur-Rahman!" He said: "Do what you did before." He rode on until the starts appeared, then he stopped and said: "Say the Iqamah, then when I say the Taslim, say the Iqamah. So he said the Iqamah and he prayed Maghrib, three Rak'ahs, then he said the Iqamah (again) straight away and he prayed 'Isha', then he said one Taslim, turning his face. Then he said: "The Messenger of Allah ﷺ said: 'If any one of you has urgent need that he fears he may miss, let him pray like this.'"  

عَنِ الصَّلاَةِ فِي السَّفَرِ فَقُلْنَا أَكَانَ عَبْدُ اللَّهِ يَجْمَعُ بَيْنَ شَىْءٍ مِنَ الصَّلَوَاتِ فِي السَّفَرِ فَقَالَ لاَ إِلاَّ بِجَمْعٍ ثُمَّ أَتَيْتُهُ فَقَالَ كَانَتْ عِنْدَهُ صَفِيَّةُ فَأَرْسَلَتْ إِلَيْهِ أَنِّي فِي آخِرِ يَوْمٍ مِنَ الدُّنْيَا وَأَوَّلِ يَوْمٍ مِنَ الآخِرَةِ فَرَكِبَ وَأَنَا مَعَهُ فَأَسْرَعَ السَّيْرَ حَتَّى حَانَتِ الصَّلاَةُ فَقَالَ لَهُ الْمُؤَذِّنُ الصَّلاَةَ يَا أَبَا عَبْدِ الرَّحْمَنِ فَسَارَ حَتَّى إِذَا كَانَ بَيْنَ الصَّلاَتَيْنِ نَزَلَ فَقَالَ لِلْمُؤَذِّنِ أَقِمْ فَإِذَا سَلَّمْتُ مِنَ الظُّهْرِ فَأَقِمْ مَكَانَكَ فَأَقَامَ فَصَلَّى الظُّهْرَ رَكْعَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ أَقَامَ مَكَانَهُ فَصَلَّى الْعَصْرَ رَكْعَتَيْنِ ثُمَّ رَكِبَ فَأَسْرَعَ السَّيْرَ حَتَّى غَابَتِ الشَّمْسُ فَقَالَ لَهُ الْمُؤَذِّنُ الصَّلاَةَ يَا أَبَا عَبْدِ الرَّحْمَنِ فَقَالَ كَفِعْلِكَ الأَوَّلِ فَسَارَ حَتَّى إِذَا اشْتَبَكَتِ النُّجُومُ نَزَلَ فَقَالَ أَقِمْ فَإِذَا سَلَّمْتُ فَأَقِمْ فَصَلَّى الْمَغْرِبَ ثَلاَثًا ثُمَّ أَقَامَ مَكَانَهُ فَصَلَّى الْعِشَاءَ الآخِرَةَ ثُمَّ سَلَّمَ وَاحِدَةً تِلْقَاءَ وَجْهِهِ ثُمَّ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ إِذَا حَضَرَ أَحَدَكُمْ أَمْرٌ يَخْشَى فَوْتَهُ فَلْيُصَلِّ هَذِهِ الصَّلاَةَ  

"I asked Salim bin 'Abdullah about how his father prayed when traveling. We asked him: 'Did he combine any of his prayers when traveling?' He said that Safiyyah bint Abi 'Ubaid was married to him, and she wrote to him, when he was at some farmland of his, saying: 'This is the last of my days in this world, and the first day of the Hereafter." [1] He rode quickly to go to her, and when the time for Zuhr came, the Mu'adhdhin said to him: "The prayer, O Abu 'Abdur-Rahman!" But he paid no attention to him until it was between the time for the two prayers, then he stopped and said: "Say the Iqamah and when I say the Taslim, say the Iqamah." Then he rode on again, and when the sun set the Mu'adhdhin said to him; "The prayer!" He said: "Do as you did for Zuhr and 'Asr." When the stars had appeared, he stopped and said to the Mu'adhdhin: "Say the Iqamah and when I say the Taslim, say the Iqamah." He prayed, then when he had finished he turned to us and said: "The Messenger of Allah ﷺ said: 'If any one of you has an urgent need that he fears he may miss, let him pray like this.'" [1] Meaning that she was dying. (Using translation from Nasāʾī 588)  

عَنْ صَلَاةِ أَبِيهِ فِي السَّفَرِ وَسَأَلْنَاهُ هَلْ كَانَ يَجْمَعُ بَيْنَ شَيْءٍ مِنْ صَلَاتِهِ فِي سَفَرٍ؟ فَذَكَرَ أَنَّ صَفِيَّةَ بِنْتَ أَبِي عُبَيْدٍ وَكَانَتْ تَحْتَهُ كَتَبَتْ إِلَيْهِ وَهُوَ فِي زِرَاعَةٍ لَهُ إِنِّي فِي آخِرِ يَوْمٍ مِنَ الدُّنْيَا وَأَوَّلِ يَوْمٍ مِنَ الْآخِرَةِ فَرَكِبَ فَأَسْرَعَ السَّيْرَ حَتَّى إِذَا حَانَتْ صَلَاةُ الظُّهْرِ قَالَ لَهُ الْمُؤَذِّنُ الصَّلَاةَ يَا أَبَا عَبْدِ الرَّحْمَنِ فَلَمْ يَلْتَفِتْ حَتَّى إِذَا كَانَ بَيْنَ الصَّلَاتَيْنِ نَزَلَ فَقَالَ أَقِمْ فَإِذَا سَلَّمْتُ فَأَقِمْ فَصَلَّى ثُمَّ رَكِبَ حَتَّى إِذَا غَابَتِ الشَّمْسُ قَالَ لَهُ الْمُؤَذِّنُ الصَّلَاةَ قَالَ كَفِعْلِكَ لِصَلَاةِ الظُّهْرِ وَالْعَصْرِ ثُمَّ سَارَ حَتَّى إِذَا اشْتَبَكَتِ النُّجُومُ نَزَلَ ثُمَّ قَالَ لِلْمُؤَذِّنِ أَقِمْ فَإِذَا سَلَّمْتُ فَأَقِمْ فَصَلَّى ثُمَّ انْصَرَفَ ثُمَّ الْتَفَتَ إِلَيْنَا فَقَالَ قَالَ رَسُولُ اللهِ ﷺ «إِذَا حَفَزَ أَحَدَكُمُ الْأَمْرُ الَّذِي يَخَافُ فَلْيُصَلِّ هَذِهِ الصَّلَاةَ»
