Every Muslim should dress well, because Allah loves beauty. As long as that beauty does not violate Allah’s boundaries and the Prophet ﷺ guidance.
A hadith from ‘Abdullah ibn Mas’ud (may Allah blesses him), that the Prophet ﷺ said,
إنَّ اللهَ جميلٌ يُحبُّ الجمالَ
“Allah is Beautiful, He loves beauty” [Muslim].
And dressing well itself, is not considered as arrogance. A hadith from ‘Abdullah ibn Mas’ud (may Allah blesses him), that the Prophet ﷺ said,
لا يدخل الجنة من كان في قلبه مثقال ذرة من كبر
“No one who has an atom’s-weight of arrogance in his heart will enter Paradise”
فقال رجل: إن الرجل يحب أن يكون ثوبه حسنًا، ونعله حسنة
A man said, “O Messenger of Allah, what if a man likes his clothes and his shoes to look good?”
فقال: إن الله جميل يحب الجمال، الكبر بَطَر الحق، وغمط الناس
He ﷺ said, “Allah is Beautiful and loves beauty. Arrogance means rejecting the truth and looking down on people” [Saheeh Muslim]ز
So, dress well and beautiful. Allah loves that. But, don’t dress in a way to boast your self.
