Yahya related to me from Malik from Nafi that Abdullah ibn Umar, shortened the prayer when he left for hajj or umra at Dhu'l Hulayfa.  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ إِذَا خَرَجَ حَاجًّا أَوْ مُعْتَمِرًا قَصَرَ الصَّلاَةَ بِذِي الْحُلَيْفَةِ  

Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah that his father rode to Rim and shortened the prayer on the journey. Malik said, "That was about four mail-stages." (approximately forty-eight miles).  

أَنَّهُ رَكِبَ إِلَى رِيمٍ فَقَصَرَ الصَّلاَةَ فِي مَسِيرِهِ ذَلِكَ قَالَ مَالِكٌ وَذَلِكَ نَحْوٌ مِنْ أَرْبَعَةِ بُرُدٍ  

Yahya related to me from Malik from Nafi from Salim ibn Abdullah that Abdullah ibn Umar rode to Dhat an-Nusub and shortened the prayer on the journey. Malik said, "There are four mail-stages between Dhat an-Nusub and Madina."  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ رَكِبَ إِلَى ذَاتِ النُّصُبِ فَقَصَرَ الصَّلاَةَ فِي مَسِيرِهِ ذَلِكَ قَالَ مَالِكٌ وَبَيْنَ ذَاتِ النُّصُبِ وَالْمَدِينَةِ أَرْبَعَةُ بُرُدٍ  

Yahya related to me from Malik from Nafi from Ibn Umar that he used to travel to Khaybar and he would shorten the prayer.  

أَنَّهُ كَانَ يُسَافِرُ إِلَى خَيْبَرَ فَيَقْصُرُ الصَّلاَةَ  

Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah that Abdullah ibn Umar used to shorten the prayer when he travelled for a whole day.  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ يَقْصُرُ الصَّلاَةَ فِي مَسِيرِهِ الْيَوْمَ التَّامَّ  

Yahya related to me from Malik from Nafi that he used to travel one mail-stage with Ibn Umar, and he would not shorten the prayer.  

أَنَّهُ كَانَ يُسَافِرُ مَعَ ابْنِ عُمَرَ الْبَرِيدَ فَلاَ يَقْصُرُ الصَّلاَةَ  

Yahya related to me from Malik that he had heard that Abdullah ibn Abbas used to shorten the prayer when he travelled a distance equivalent to that between Makka and Ta'if, and that between Makka and Usfan and that between Makka and Jedda. Malik said, "That is four mail-stages, and to me that is the most preferable distance for shortening the prayer." Malik said, "Someone who intends to travel does not shorten the prayer until he has left the houses of the village. And he does not do it in full until he comes to the first houses of the village, or is nearby."  

أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ كَانَ يَقْصُرُ الصَّلاَةَ فِي مِثْلِ مَا بَيْنَ مَكَّةَ وَالطَّائِفِ وَفِي مِثْلِ مَا بَيْنَ مَكَّةَ وَعُسْفَانَ وَفِي مِثْلِ مَا بَيْنَ مَكَّةَ وَجُدَّةَ قَالَ مَالِكٌ وَذَلِكَ أَرْبَعَةُ بُرُدٍ وَذَلِكَ أَحَبُّ مَا تُقْصَرُ إِلَىَّ فِيهِ الصَّلاَةُ قَالَ مَالِكٌ لاَ يَقْصُرُ الَّذِي يُرِيدُ السَّفَرَ الصَّلاَةَ حَتَّى يَخْرُجَ مِنْ بُيُوتِ الْقَرْيَةِ وَلاَ يُتِمُّ حَتَّى يَدْخُلَ أَوَّلَ بُيُوتِ الْقَرْيَةِ أَوْ يُقَارِبُ ذَلِكَ
