Abu ʿAbdillah Muhammad ibn Idris ash-Shafi’ee 204 AH (May Allah have mercy on him) said,

اصبر على مر الجفا من معلم *** فإن رسوب العلم في نفراته
Be patient over the teacher’s strictness and harshness
For the stores of knowledge are present in his harshness

ومن لم يذق ذل التعلم ساعة *** تجرع ذل الجهل طول حياته
Whoever does not taste the humility of learning, even for an hour
Will drink the humility of ignorance for the rest of his life

ومن فاته التعليم وقت شبابه *** فكبر عليه أربعا لوفاته
For him who misses out on learning in his youth,
Then announce four takbirs over him for his death is due

حياة الفتى – والله – بالعلم والتقى *** إذا لم يكونا لا اعتبار لذاته
By Allah, the life of a youth is by knowledge and piety
If they are not present, then nothing can express his
