“The people gathered together and were going over which of the blessings (of Allāh) is the best? A man said: ‘That which Allāh has concealed of (our shortcomings from) each other’.” He said: “So they view that to be strongest statement.”

[Hilyah Al-Awliyā 6/131]

Shaykhul-Islām Ibn Taymiyyah رحمه الله stated:

“The one who is withheld is the one whose heart is withheld from its Lord. And the prisoner is the one whose desires has imprisoned him.”
