The scholars have mentioned that whoever satisfies his limbs with evil temptations and desires, has indeed planted in his heart seeds of regret.
And these seeds will continue to grow until they completely overwhelm a person, resulting in that person falling into spiritual depression and anxiety.
Therefore, the Muslim must be careful, and continuously seek Allahs forgiveness and turn to Him in repentance.
And the greatest matter that will keep you away from sins and transgression, is seeking knowledge, and engaging in righteous deeds, both of which never end.
Allah ﷻ describes the believers:
وَيَدرَءونَ بِالحَسَنَةِ السَّيِّئَةَ
“And they push away evil with good”.
Surat Ar-Raad:22
