Qalb

Ash-Shu'ara 26:89

Except one who comes to Allah with a sound heart.

Qaf 50:37

Indeed in that is a reminder for whoever has a heart.

Allah has sealed up their hearts and ears and a covering has fallen over their eyes, and they have incurred the severest punishment

In their hearts is a disease which Allah has increased all the more and a painful doom is in store for them for the lie they utter

But even after seeing these Signs your hearts hardened and became as hard as rocks; nay, even harder than rocks. For there are some rocks out of which springs gush forth, and others which split open, and water issues out of them; then there are some which tumble down for fear of Allah. And Allah is not unaware of what you are doing

They say, "Our hearts are secure." Nay, the fact is that Allah has cursed them for their disbelief; so they are little disposed to believe

Recall also to mind the Covenant We made with you while We raised the Tur over you: `Follow strictly the precepts We are giving you and give ear to Our Commandments.' Your forefathers replied, "We have heard but we will not obey." They were so prone to unbelief that they cherished the calf in their hearts. Tell them (O Muhammad). "If indeed you are believers, yours is a strange Faith that enjoins you to do such evil things

Say to them, "Whoever is enemy to Gabriel, should understand that he has, by Allah's command, revealed to your heart the Qur'an which confirms what was revealed before it, and brings Guidance and glad tidings to the Believers

The ignorant people say, "Why does not Allah Himself talk to us or why does not a Sign come to us?" The people before them also talked like this, for all (who swerve from the Right Path) have the same mentality. We have already shown clear Signs to those who believe

Thus have We made you a Community of the "Golden Mean" so that you may be witnesses in regard to mankind and the Messenger may be a witness in regard to you. We had appointed the former giblah towards which you used to turn your face merely to test who would follow the Messenger and who would turn back. It was indeed a hard test but not for those who had been blessed with Guidance from Allah. Allah will not let go to waste this faith of yours; rest assured that He is full of pity and mercy for mankind

We have seen you (O Muhammad), turning your face over and over again towards Heaven. Now, therefore, We turn you towards the giblah that you like best: so turn your face towards the Masjid Haram. Henceforth, wheresoever you may be, turn your face at prayer towards it. The people who were given the Book know it well that the commandment (about the change of giblah) is in fact from their Lord, and is based on the Truth, but Allah is not unaware of what they are doing (in spite of this)

There is a certain type of man who charms you in this worldly life with his glib talk. He calls Allah to witness again and again that he cherishes good intentions in his heart, whereas, in fact, he is the deadliest opponent of the Truth

Allah hears everything you utter and knows everything. Allah does not call you to Account for unintentional and meaningless oaths, but will surely take you to task for oaths taken deliberately and in earnest: Allah is Forgiving and Forbearing

Call to mind the other event also, when Abraham said, "My Lord, show me how Thou bringest the dead back to life?" He said "Have you no faith in this?" Abraham humbly replied, "I do believe but I ask this to reassure my heart." Allah said, "Well, take four birds and tame them with yourself and then (cut them into pieces) and place a piece of each of them on each hill. Then call them and they will come running to you; know this for certain that Allah is All-Powerful, All-Wise

If you are on a journey and cannot find a scribe to write the document, then transact your business on the security of a pledge in hand. And, if any one transacts a piece of business with another merely on trust, then the one who is trusted should fulfil his trust and fear Allah, his Lord And never conceal evidence for he who conceals it, has a sinful heart: Allah knows everything that you do

It is He Who has revealed the Book to you. Some of its verses are absolutely clear and lucid, and these are the core of the Book. Others are ambiguous. Those in whose hearts there is perversity, always go about the part which is ambiguous, seeking mischief and seeking to arrive at its meaning arbitrarily, although none knows their true meaning except Allah. On the contrary, those firmly rooted in knowledge say: 'We believe in it; it is all from our Lord alone.' No one derives true admonition from anything except the men of understanding

They pray to Allah: 'Our Lord! Do not let our hearts swerve towards crookedness after You have guided us to the right way, and. bestow upon us Your mercy. Surely You, only You, are the Munificent Giver

Hold fast together to the cable of Allah and be not divided. Remember the blessing that Allah bestowed upon you: you were once enemies then He brought your hearts together, so that through His blessing you became brothers. You stood on the brink of a pit of fire and He delivered you from it. Thus Allah makes His signs clear to you that you may be guided to the right way

Allah has reminded you of this only as a glad tiding to you and so as to let your hearts be at rest. Help can only come from Allah, the All-Mighty, the All-Wise

And Allah provided this aid to you in order to cut off a part of those who disbelieved and frustrate them so that they retreat in utter disappointment

Muhammad is no more than a Messenger, and Messengers have passed away before him. If, then, he were to die or be slain will you turn about on your heels? Whoever turns about on his heels can in no way harm Allah. As for the grateful ones, Allah will soon reward them

Believers! If you follow those who deny the Truth, they will drive you back on your heels, and you will turn about, losers
