Riyad as-Salihin 84

There were two brothers in the days of the Prophet (sallallahu alayhi wa sallam). One of them used to attend the Prophet’s circle (to acquire knowledge) and the other used to earn their living). Once the latter complained to the Prophet (sallallahu alayhi wa sallam) against the former (for not earning his living). He (sallallahu alayhi wa sallam) replied, “Perhaps you are being provided because of him”.
