Keywords: Existence; Heart; al-Qalb I. INTRODUCTION The Prophet, as the noblest human being, has a mission to convey the risalahilahi (the letter of God). Risalahilahi is the revelation in the form of the Qur'an and hadith. Al-Qur'an and hadith are sources of law for Muslims. However, according to Muslim scholars, both of them are different in quality. The whole Qur'an is recognized its existence (qat}‘i> al-dila>lah), while the hadith generally is still an estimation of its existence (z}anni> al-dila>lah). Therefore, a new hadith can be true after clarifying it through research on its sanad and matan. The existence of hadiths is considered when the hadits are contained in the books of s}ah}i>h}ain (S}ah}i>h} al- Bukha>ri> and S}ah}i>h } Muslims), because the majority of scholars apply the requirements in selecting hadith, namely the continued sanad, the narrators are fair and strong in maintenance (d}a>bit} ), not having illat and not contradicting. In terms of the content of the discussion, the Qur'an and hadith contain discussions about worship, law, and mu'amalah. One of the contents conveyed by both of them is a matter of the heart. For example, in the Qur'an, it is stated that it turns out that bad deeds can cover the heart, as Allah says in QS. al-Mut}affifi>n/83: 14, as follows.  ك  ون ُ ب ِ س ْ ك  واي ُ ان  اك  م ْ م ِ  ِ  و ُ ل ُ ىق  ل  ع  ان  ر ْ ل  ب ا ل
