Prophet Muhammad said:
No one will enter Paradise who has an ant’s weight of pride in his heart.
A man said:
“What if a man likes his clothes to look good and his shoes to look good?”
God is beautiful and loves beauty. Pride means denying the truth and looking down on people. (Muslim)
Beauty is the opposite of ugliness. The beauty that exists in creation attests to God’s beauty as well as His power. He who created beauty is the most entitled to beauty.
And indeed Paradise is adorned with beauty beyond imagining. God is beautiful and this is why the greatest of all pleasures in Paradise is to look upon God’s Face. God says:
[Some] faces, that Day, will be radiant; looking to their Lord. (75: 22-23)
He refers to His names as being the Most Beautiful:
And the Most Beautiful Names belong to God, so call on Him by them… (7:180)
Noted Islamic scholar Ibn Al-Qayyim had the following to say about beauty in Islam:
“God is to be acknowledged for beauty that bears no resemblance to anything else, and He is to be worshiped by means of the beauty which He loves in words, deeds and attitudes.
God loves His slaves to beautify their tongues with the truth, to beautify their hearts with sincere devotion, love, repentance and trust in Him, to beautify their faculties with obedience, and to beautify their bodies by showing His blessings upon them in their clothing and by keeping them pure and free of any filth, dirt or impurity, by removing the hairs which should be removed, by circumcision, and by clipping the nails.
Thus they recognize God through these qualities of beauty and seek to draw close to Him through beautiful words, deeds and attitudes.
They acknowledge Him for the beauty which is His attribute and they worship Him through the beauty which He has prescribed and His religion.” (Al-Fawaa’id, 1/185)
