Hifz of Qur'aan

It has been attributed to Ibn Mas'uud that he said:

Memorizing the Qur'aan is difficult for us but acting on it is easy for us.  Indeed, there will after us those for him memorizing the Qur'aan will be easy but acting on it will be difficult.

قال  عبد الله بن مسعود رضي الله عنه
إنّا صَعُب علينا حفظ القرآن وسهُل علينا العمل به وإن مَن بعدنا يسهل عليهم حفظ القرآن ويصعب عليهم العمل به

القرطبي
