Heart in the Quran

Do you think that we had use the heart given correctly? Have we fully capitalize the nikmat given? Rasulallah mention:

On the authority of Abu 'Abdullah al-Nu'man bin Bashir, radiyallahu 'anhu, who said: I heard the Messenger of Allah, sallallahu 'alayhi wasallam, say:

Love

"Truly, what is lawful is evident, and what is unlawful is evident, and in between the two are matters which are doubtful which many people do not know. He who guards against doubtful things keeps his religion and honour blameless, and he who indulges in doubtful things indulges in fact in unlawful things, just as a shepherd who pastures his flock round a preserve will soon pasture them in it. Beware, every king has a preserve, and the things Allah has declared unlawful are His preserves. Beware, in the body there is a flesh; if it is sound, the whole body is sound, and if it is corrupt, the whole body is corrupt, and behold, it is the heart."[Al-Bukhari & Muslim]

Jika baik hati itu maka baiklah seluruh jasadnya=D
Some says, our behaviour would portray our heart condition. A good person, have a good heart. That is the basic idea. A normal scenario in our community,

"Alaahh, diorang yang pakai tudung pun perangai lagi buruk"

What do you think? I am still thinking a perfect answer to give myself. But I believe, it is not that tudung that will determine whether you are a good person or not. But when you have your hijab on, meaning that you have obey Allah's word, Allah's rule. And I believe that is the most important.

يَا أَيُّهَا الَّذِينَ آمَنُوا ادْخُلُوا فِي السِّلْمِ كَافَّةً وَلَا تَتَّبِعُوا خُطُوَاتِ الشَّيْطَانِ إِنَّهُ لَكُمْ عَدُوٌّ مُبِينٌ
O ye who believe! Enter into Islam whole-heartedly; and follow not the footsteps of the evil one; for he is to you an avowed enemy.[2:208]

So we cant choose. Ok in this part(let say solah) I would like to follow Islam's rule, while in this (let say hijab) I dont want to. It totally against the ayat. And to be highlighted, Allah stress in the ayah, "O ye who believe (Wahai orang2 yang beriman)" and who is it? Isnt it us?
And about behaviour, it is actually the reflection of your heart. With a good hear, secara fitrahnya you would have a good manner.

"And certainly We have created for hell many of the jinn and the men; they have hearts with which they do not understand, and they have eyes with which they do not see, and they have ears with which they do not hear; they are as cattle, nay, they are in worse errors; these are the heedless ones."[7:179]

Allah regard heart is to be use to understand His words(quran), ears to listen to His command(ayat2 quran)
