Bandar seri begawan: Muslims are reminded to always try to take care of their hearts by increasing zikir and reading the Quran. If the heart is clean, calm, and illuminated by the light of faith, then all parts of the body will also be subject to goodness and used to carry out righteous deeds that are pleasing to Allah Subhanahu Wata'ala. The matter was stated in the Friday Sermon titled "Cleansing The Heart, Attaining a Sound Heart". Having a clean and safe heart is the dream of every Muslim. To achieve it, Muslims must make a sincere effort to maintain and preserve several things. First, Hablun Minallah, which is maintaining a relationship with Allah Subhanahu Wata'ala, especially by maintaining prayers and performing them on time.
According to Radio Television Brunei, the second point emphasized in the sermon is reviving the culture of reading the Quran. The Quran is medicine for the heart. Muslims are encouraged to read, internalize, and practice the teachings of the Quran. Consistency is stressed, even if the reading is done in small amounts but continuously. Third, increasing zikir and istighfar is highlighted as zikir acts to calm a restless heart, and istighfar cleanses stains. Zikir also trains individuals to control emotions such as anger, envy, and grievances.
The sermon further advises maintaining good manners in speech and on social media. A dark heart is not only due to major sins but also due to the sins of the tongue, such as gossiping, defamation, belittling others, spreading disgrace, and writing without knowledge or verification of the truthfulness of something. Lastly, the importance of Hablum Minannas, maintaining relationships with fellow humans, is emphasized for achieving a sound heart.
