I'm so surprised at how much people speak about Islaam as if they're so knowledgable about it.
Allaah says in the Qur'an (translation of the meaning):
That home of the Hereafter (i.e. Paradise) We assign to those who do not desire exaltedness upon the earth or corruption. And the [best] outcome is for the righteous.
[Qur'an 28: 83]
And the true servants of the Most Merciful are those who walk the earth with humility and when the ignorant address them, they respond with words of peace.
And Allaah narrates to us what Luqman said to his son:
O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] determination.
"And turn not your face away from men with pride, nor walk in insolence through the earth. Verily, Allah likes not each arrogant boaster.
And be moderate (or show no insolence) in your walking, and lower your voice. Verily, the harshest of all voices is the voice (braying) of the ass (donkey)."
[Qur'an 31: 17-19]
The Prophet, may Allah bless him and grant him peace, said, "No one who has an atom's weight of pride in his heart will enter the Garden." A man said, "And if the man likes his clothes to be good and his sandals to be good?" He said, "Allah is Beautiful and loves beauty. Pride means to renounce the truth and abase [look down on] people." [Saheeh Muslim]
Haritha ibn Wahb said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'Shall I tell you about the people of the Fire? All those who are coarse, domineering, and arrogant.'" [Agreed upon]
Allaah tells us who the greatest among mankind are;
O mankind! We have created you from a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honourable of you with Allah is that (believer) who has At-Taqwa
[i.e. one of the Muttaqun (pious.] Verily, Allah is All-Knowing, All-Aware.
[Qur'an 49: 13]
piety, "God-consciousness." Taqwa involves constant awareness and remembrance of Allah, and conscious efforts to adhere to His commandments and abstain from whatever He has forbidden.
None of us should boast in pride that "I have the most taqwa" since it is Allaah Alone knows who truelly is good. So we remain modest and continue doing good deeds, hoping to gain Allaah's Mercy for the good we do, so that we may enter His paradise. Yet to be arrogant about the deeds we do is an attribute of satan, and it shows a lack of sincerety.
And Allaah knows best.
