Ibn ‘Abbas said that 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.’’(Qur’an 2:197) Bukhari transmitted it.
