عَنِ ابْنِ عَبَّاسٍ
قَالَ: كَانَ أَهْلُ الْيَمَنِ يَحُجُّونَ فَلَا يَتَزَوَّدُونَ وَيَقُولُونَ: نَحْنُ الْمُتَوَكِّلُونَ فَإِذَا قَدِمُوا مَكَّةَ سَأَلُوا النَّاسَ فَأَنْزَلَ اللَّهُ تَعَالَى: (وتزَوَّدُوا فإِنَّ خيرَ الزَّادِ التَّقوى)
The people of the Yemen used to perform the pilgrimage without bringing provisions, declaring that they put their trust in God; and when they came to Mecca they begged from the people. So God most high sent down, “And bring provisions, but the best provision is piety.”(Al-Baqarah 2:197)
