Qur'an defines a sound heart as turning to and submitting fully to Allah, having fear and love of Allah as much as one can and a sincere faith.
Those who believe and whose hearts find peace in the remembrance of Allah. Only in the remembrance of Allah can the heart find peace. (Surat ar-Ra’d, 28)
A sound heart in the Islamic context means a heart that is purified from all forms of impurity that draw one away from Allah.
Truly Allah has knowledge of the Hour, sends down abundant rain, and knows what is in the womb. And no self knows what it will earn tomorrow, and no self knows in what land it will die. Allah is All-Knowing, All-Aware. (Surah Luqman, 34)

'Ali Ibn Abi Talib (radiyallahu anhu) said: "Whoever has the following six characteristics does all that is required to make him enter Paradise and avoid Hell: to know Allah (M) and obey him, to know Satan and disobey him, to know the truth and follow it, to know falsehood and avoid it, to know the life of this world and renounce it and to know the Hereafter and seek it."

Allah's message, one of the things that the believer who is qualified to do so
has to do is develop himself and to gain every kind of useful knowledge in
order to communicate Allah's deen
