«وَأَنْضِيَ إِلَيْهِ رِكَابَ الطَّلَبِ»
And wear out the mounts of seeking in order to reach it.
Rikāb refers to riding animals, while anḍiya suggests exhausting them through strenuous travel. The expression is metaphorical: the desire to learn is imagined as a traveler whose mount grows tired.
The narrator's passion is not passive. It takes the form of deliberate effort and repeated journeys.
