Allaah (The Most High) said:
يَوْمَ لَا يَنْفَعُ مَالٌ وَلَا بَنُونَ
إِلَّا مَنْ أَتَى اللهَ بِقَلْبٍ سَلِيمٍ
The Day whereon neither wealth nor sons will avail; Except him who brings to Allah a clean heart. [Soorah Ash-Shu’araa..Aayaat 88-89]
This (i.e. clean heart) is what will benefit you, save you from punishment and make you worthy of abundant reward (i.e. in the afterlife).
Some Characteristics of the Clean Heart
It is free from Shirk, doubt (i.e. about the religion) and love of evil.
It does not persist upon Bidah and Sins (i.e. it returns to repentance).
It is characterised with sincerity, certainty (i.e. about the religion) and love of good.
What it loves and desires agrees with what Allaah loves and what Allaah has revealed (i.e. the Qur’aan and the Sunnah).
