From the Terrible Harms of Boredom

Imām Ibn Al-Qayyim, may Allāh have mercy on him, said:

Nothing is more harmful to a slave-worshiper than his becoming bored of Allāh’s blessings [and favors], for then he will really not see them as blessings, nor express his gratitude to Him for them, nor feel any happiness about them; rather, he will feel angry and resentful about them, complain about them, and consider them calamities–[all] this, while they [might] be from among the greatest of Allāh’s blessings upon him.

So most people are enemies to the blessings of Allāh upon them, and they don’t realize it.

Al-Fawāʾid, p. 263, as quoted by Shaikh ʿAbdullāh Al-Bukhārī.
