Quran

Abdulla bin Masoud (t) said: "They will be given light commensurate with their deeds. Some will be given their light as high as a palm tree, for others, it will be as high as a standing person, and the least light given will be as little as the tip of a person’s thumb where it comes on and goes out repeatedly." Al-Baghawi: 4/324.

This will become the biggest regret and affliction, when one is shown the way to safety and salvation until he believes he is saved and sees the dwellings of those who are destined for bliss, he is cut off from them and overcome with misfortune.

(Should be humbled), this means to be in a higher stage of faith, where their hearts soften, calm down, submit, become humiliated and reassured, and turn away from perishable life and seek the eternal one.

Hence, the remembrance of Allah (the Quran), becomes remedy for the faith and cure for the sickness of the heart, as Allah's remembrance clears the taints of the hearts. Al-Biqai: 19/279.
Question: What is the best cure for the hardened heart?

(Hardened), due to the passing of time. (Their hearts), became stiffened and bent to the point where they were not prone to obedience and goodness. Al-Qushayri said: Hardness of the heart results from pursuing desires, and clarity of the heart and following desires do not coexist. Al-Biqai: 19/280.

This description likens the need of the believers' hearts for the remembrance of Allah to the dry land in need of rain, and the effect of the remembrance of Allah in purifying and enlightening the souls to that of the rain reviving the barren land. Ibn Ashur: 27/393.
