حَدَّثَنَا يَحْيَى بْنُ يَحْيَى التَّمِيمِيُّ قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ يَحْيَى بْنِ أَبِي كَثِيرٍ قَالَ سَمِعْتُ أَبِي يَقُولُا لَا يُسْتَطَاعُ الْعِلْمُ بِرَاحَةِ الْجِسْمِ

Narrated to us by Yahya bin Yahya At Tamimi, he said he informed us Abdullah bin Yahya bin Abu Katsir he said I heard his father say 'Knowledge cannot be obtained by resting the body (lazily).'
