Question: If a person has harshness and cruelty in his heart [towards others], then what can soften his heart from this harshness and cruelty?
Response: There is nothing better nor befitting than the Noble Qur.aan; that is what shall soften his heart, as Allaah Jalla wa ‘Alaa said:
{Those who believed [in the Oneness of Allaah], and whose hearts find rest in the remembrance of Allaah, verily, in the remembrance of Allaah do hearts find rest.}, soorah ar-Ra’d, aayah 28
So that which softens the hearts is the Qur.aan, if Allaah were to reveal it;
{…on a mountain, you would surely have seen it humbling itself and rent asunder by the fear of Allaah}, soorah al-Hashr, aayah 21
And likewise the gatherings of the righteous, as well as listening to the Qur.aan, and listening to lectures [encouraging one another upon good], and the [general] remembrance [of Allaah] – this is what shall soften the hearts [in shaa.-Allaah].
