"A man came to the Prophet and said: 'O Messenger of Allah! What is it that makes Hajj obligatory?' He said: "The provisions and a means of conveyance."  

الترمذي:٨١٣حَدَّثَنَا يُوسُفُ بْنُ عِيسَى حَدَّثَنَا وَكِيعٌ حَدَّثَنَا إِبْرَاهِيمُ بْنُ يَزِيدَ عَنْ مُحَمَّدِ بْنِ عَبَّادِ بْنِ جَعْفَرٍ عَنِ ابْنِ عُمَرَ قَالَ

جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ مَا يُوجِبُ الْحَجَّ قَالَ الزَّادُ وَالرَّاحِلَةُ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ وَالْعَمَلُ عَلَيْهِ عِنْدَ أَهْلِ الْعِلْمِ أَنَّ الرَّجُلَ إِذَا مَلَكَ زَادًا وَرَاحِلَةً وَجَبَ عَلَيْهِ الْحَجُّ وَإِبْرَاهِيمُ بْنُ يَزِيدَ هُوَ الْخُوزِيُّ الْمَكِّيُّ وَقَدْ تَكَلَّمَ فِيهِ بَعْضُ أَهْلِ الْعِلْمِ مِنْ قِبَلِ حِفْظِهِ
