It is reported that Abūl-ʿĀliyah said:

There will come upon the people a time when their hearts will be derelict of the Qurān; they will find neither sweetness nor pleasure by it. If they fall short of doing what they have been commanded to do, they will say: Allāh is most forgiving, merciful (He will forgive us), and if they do what they have been forbidden from doing, they will say: we will be forgiven, we haven’t committed any shirk with Allāh. Their affairs will all be based on [false] hope, having no truth and sincerity with it. They will wear the skins of lambs over hearts of wolves. The best of them in his religion will be someone who compromises.

Imām Aḥmad, Al-Zuhd article 1741.

It is reported that Abū Al-Dardā' – Allāh be pleased with him – said:

There is no good in this life except for one of two men: a man listening carefully, receiving and holding [knowledge]; or someone knowledgeable speaking.

Ibn Ḥibbān, Rawḍatu Al-ʿUqalāʾ 1:42.
