Lack of Concern about Clothing out of Asceticism

Question :

Some youth today are remiss in taking care of their appearance, doing so out of a sense of asceticism and lack of concern for worldly garments, and that such concern is a waste of time. Others have told them that this contradicts. the Hadith:
"Indeed, Allah is beautiful and He loves beauty."
Please give us your view on this issue, may Allah reward you.

Answer:

In one Hadith it is mentioned that if Allah Almighty blesses His servant, He likes to see the effects of His blessing on him. Correct asceticism (Az-Zuhd) is praiseworthy, for the Prophet ﷺ said:
"Practice Zuhd in the world, Allah will love you."

That is, the lack of concern with sexual relations and seeking an increase in wealth which would divert one form the Hereafter. But when Allah provides a servant with wealth that is lawful and provides him with blessings, then it is the right of these blessings that he show gratitude and use them for what Allâh loves. In this vain, Allâh has permitted the good things for sustenance and ordered the usage of adornment, or clothing. Lack of concern for one's appearance leads to an objectionable appearance. So moderation in clothing is what is preferred. not being extravagant or lavish, nor stingy and tight-fisted.

And with Allah is the facilitation to do what is right.
