signs, symptoms and cures of the spiritual diseases of the heart
Love of this world is considered blameworthy, though this does not include wanting things of this world in order to be free from burdening others with one's needs, nor does it include desiring provision from the world for the purpose of attaining the best of the Hereafter.
For example, we should love aspects of this world that helps us achieve felicity in the Hereafter, such as the Qur'an, the Ka'ba, the Prophet ﷺ, our parents, godly people, books of knowledge, children, and others who help us in our religious affairs. As for wealth, we should love helping the needy with it.
Love of the world is praised or blamed based on what good or harm it brings to a person. If it leads to a diseased heart—such as greediness and arrogance—then it is blameworthy. If it leads to spiritual elevation and healing of the heart, then it is praiseworthy. Anything that is obtained from the necessities of living on earth—food, housing, shelter, and the like—is beneficial and is not considered "worldly" per se.
Attaining wealth and position for the benefit of the needy is not considered blameworthy.
[Love of praise:] People naturally love praise, but it should be for something one has actually done. Furthermore, the cause of praise should be something that is praiseworthy in the sight of God. It is not necessarily wrong to want people to appreciate what one has done. One must make the distinction between flattery and appreciation. The Prophet ﷺ said, "Throw dirt in the faces of flatterers," those who pour accolades upon others, worthy or not, like poets who compose appallingly obsequious poetry praising a tyrant.
Praising or thanking someone for doing good is expressing gratitude. Flatter, on the other hand, is being disingenuous with praise.
What scholars traditionally have warned against, with regard to attaining wealth, is the danger of eventual transgression. The more wealth one acquires, the higher the probability that one will become preoccupied with other than God. Also, vying for wealth can become an addiction and lead to ostentation, which is considered a disease of the heart.
Love of praise is another disease, particularly the love of praise for something one has not done. This is caused by desiring something from other than God.
People often praise others because they want something from them. What is particularly blameworthy is when people enjoy receiving praise for something they have not done.
For example, in academia, some professors receive tribute for work their students actually did. In the corporate culture, it is not unheard of for managers to be credited for the accomplishment of a team of people, to whom the managers sometimes attribute nothing.
"The world is a bridge; so pass over it to the next world, but do not try to build on it" (Jesus, peace be upon him).
"Do not curse the world, for God created the world, and the world is a means to reaching [knowledge of] God" (the Prophet ﷺ)
"And He has subjugated for you what is in the heavens and what is on earth, all of it from Him. Indeed, therein are sure signs for a people who reflect" (The Qur'an, 45:13).
When the Prophet ﷺ learned of the good that someone had done, he would say, "May God reward you with goodness."
"Whoever is not thankful to people will not be thankful to God" (the Prophet ﷺ).
"Do not think that those who rejoice in what they have done and who love to be praised for what they have not done—do not think that they will escape punishment. Theirs shall be a painful chastisement" (The Qur'an, 3:188).
