Humbleness.
One of the trait of a Muslim is that he feels humbled, seeing himself as slave of Allah. He prefers the people even those living in poverty over himself.
He acknowledges that everything he has, his wealth, his children, and his body doesn't belong to him but they all belong to Allah and that He has granted him as trusts. Therefore he avoids boasting.
Allah says in Quran
وَعِبَادُ ٱلرَّحْمَـٰنِ ٱلَّذِينَ يَمْشُونَ عَلَى ٱلْأَرْضِ هَوْنًۭا وَإِذَا خَاطَبَهُمُ ٱلْجَـٰهِلُونَ قَالُوا۟ سَلَـٰمًۭا
The ˹true˺ servants of the Most Compassionate are those who walk on the earth humbly, and when the foolish address them ˹improperly˺, they only respond with peace. Surah Furqan 63
۞ وَٱعْبُدُوا۟ ٱللَّهَ وَلَا تُشْرِكُوا۟ بِهِۦ شَيْـًۭٔا ۖ وَبِٱلْوَٰلِدَيْنِ إِحْسَـٰنًۭا وَبِذِى ٱلْقُرْبَىٰ وَٱلْيَتَـٰمَىٰ وَٱلْمَسَـٰكِينِ وَٱلْجَارِ ذِى ٱلْقُرْبَىٰ وَٱلْجَارِ ٱلْجُنُبِ وَٱلصَّاحِبِ بِٱلْجَنۢبِ وَٱبْنِ ٱلسَّبِيلِ وَمَا مَلَكَتْ أَيْمَـٰنُكُمْ ۗ إِنَّ ٱللَّهَ لَا يُحِبُّ مَن كَانَ مُخْتَالًۭا فَخُورًا
Worship Allah ˹alone˺ and associate none with Him. And be kind to parents, relatives, orphans, the poor, near and distant neighbours, close friends, ˹needy˺ travellers, and those ˹bondspeople˺ in your possession. Surely Allah does not like whoever is arrogant, boastful—
Surah An-Nisa 36
And Prophet peace be upon him said
“Allah has revealed to me that you should be humble towards one another so that none of you boasts to another.”
Ibn Majah
Sunnah.com reference : Book 37, Hadith 80
English reference : Vol. 5, Book 37, Hadith 4179
Arabic reference : Book 37, Hadith 4319
Arrogance and pride is path to Hellfire, as it is reported in ahadith.
It is narrated on the authority of 'Abdullah that the Messenger of Allah (ﷺ) observed:
He who has in his heart the weight of a mustard seed of pride shall not enter Paradise.
Sahih Muslim 91c
Satan refused to obey Allah out of his arrogance, he felt that he was better than Adam peace be upon him. Thus he was cursed forever and expelled from Paradise, and will be in Hellfire.
How terrible pride can be!
Pride is not about wearing beautiful clothing and having lot of wealth as long as that don't lead to the pride. It is about rejecting the Truth, looking down on people.
Man should know that he was once a sperm, and that he carries fece in his body, that his body will rot after his death and will be thrown away in a grave, just like all human beings.
He also should acknowledge that he depends on Allah. Who is Independent Being and has no need of anything. For He is Most Praiseworthy.
Allah does not look at our appearance and wealth but He looks at our hearts.
He says in the Quran
يَـٰٓأَيُّهَا ٱلنَّاسُ إِنَّا خَلَقْنَـٰكُم مِّن ذَكَرٍۢ وَأُنثَىٰ وَجَعَلْنَـٰكُمْ شُعُوبًۭا وَقَبَآئِلَ لِتَعَارَفُوٓا۟ ۚ إِنَّ أَكْرَمَكُمْ عِندَ ٱللَّهِ أَتْقَىٰكُمْ ۚ إِنَّ ٱللَّهَ عَلِيمٌ خَبِيرٌۭ
O humanity! Indeed, We created you from a male and a female and made you into peoples and tribes so that you may ˹get to˺ know one another. Surely the noblest of you in the sight of Allah is the most righteous among you. Allah is truly All-Knowing, All-Aware
Surah Al-Hujurat 13
Prophet peace be upon him said:
O people, your Lord is one and your father Adam is one. There is no favor of an Arab over a foreigner, nor a foreigner over an Arab, and neither white skin over black skin, nor black skin over white skin, except by righteousness. Have I not delivered the message?
Source: Musnad Aḥmad 22978, Grade: Sahih
Wealthy or poor, black or white, Arab or non Arab. No one is superior except by piety.
Being the son of a politician doesn't make you superior, being the son of a well-respected scholar doesn't make you superior, unless you start practicing Islam and try to have the best character according to your ability otherwise a practicing black slave will end up being better than you...
May Allah forgive our sins and grant us beautiful character.
And Allah knows best.
