Quran :- (49:13) Human beings, We( Allah) created you all from a male and a female, and made you into nations and tribes so that you may know one another. Verily the noblest of you in the sight of Allah is the most God-fearing of you. Surely Allah is All-Knowing, All-Aware.
“It is not taqwa that you turn your faces toward East or West, but it is taqwa to believe in Allah and the Last Day, and the Angels, and the Book and the Messengers, to spend of your substance out of love for Him, for your kin, for orphans, for the needy, for the wayfarer, for those who ask, and for the ransom of slaves; to be steadfast in prayer and practice regular charity; to fulfill the contracts you have made; to be firm and patient, in pain and adversity. Those are the truthful and those are the muttaqun.” [Qur’an 2:177]
And the Prophet said: (صلى الله عليه وسلم)
"0 you people! Your Lord is One. Your (original) father is one. All of you are offspring’s of Adam, and Adam's origin was dust. The noblest among you is the most God-fearing person. An Arab does not have a right to claim superiority over a non-Arab, nor has a non-Arab a right to claim superiority over an Arab, except through righteous deeds. 0 Lord ! Please witness that I have conveyed (the message). And (you listeners), let those who are now present convey to those who are absent".
The Prophet (صلى الله عليه وسلم) said, “The most common thing which leads people to Paradise is taqwa of Allah and good conduct, and the most common thing which leads people to the Hell Fire is the mouth and the private parts.” [Tirmidhi]
Allah’s Messenger (Peace and Blessings be Upon Him), in one of his Hadiths says:” Lawful things are defined, so are unlawful things. However, there are some suspicious things between these two. When a shepherd puts his sheep out to pasture near a forest, there is a possibility that sheep could enter into that forest at any time; similarly, the one who does not refrain from doubtful things could go into harams. “
Hadrat Umar ibn Khattab (R.A) once asked Hadrat Ibn Ka’ab (R.A) the definition of taqwa. In reply Hadrat Ibn Ka’ab asked, “Have you ever had to traverse a thorny path?” Hadrat Umar replied in the affirmative and Hadrat Ka’ab continued, “How do you do so?”
Hadrat Umar said that he would carefully walk through after first having collected all loose and flowing clothing in his hands so nothing gets caught in the thorns hence injuring him. Hadrat Ka’ab said, “This is the definition of taqwa, to protect oneself from sin through life’s dangerous journey so that one can successfully complete the journey unscathed by sin.”
Umar ibn Abdul Aziz (ra) once said, "Taqwa is not by fasting the day and not by praying the night. And it's not by mixing between the two of them. But taqwa is leaving what Allah (swt) has made Haram and by doing what Allah (swt) has made Fard. After one has done this, Allah (swt) will provide good things for that person."
Hadrat Hasan Basri said, “Taqwa is the basis of Deen. Desire and greed destroy this basis.”
This Hadith about bankruptcy is dreadful and terrifying:
“Bankrupt from my Ummah is a person that comes with deeds such as prayers, fast and alms in the Doomsday. Nonetheless, he swore at people, slandered, defrauded them, and hurt or chastised some of them. His rewards are divided up among those people whom he harmed. If his deeds do not suffice, then some misdeeds of those people are placed onto him and he is sent to hell.”
