Imam an-Nawawi (may Allah have mercy upon him) said:

“He (a student of knowledge) should not belittle a benefit he saw or heard, whatever subject it may be. Rather he should hasten to write it down and then regularly review what he has recorded” [al-Majmoo’ (1/70) as cited by Shaikh Mohammed bin Maani in Al-Fawaakih al-Janniyyah (pg. 26)]
