The videos you watch and the messages you read become a part of your heart and have an impact on your mind and beliefs.
You have only one heart and it’s the most precious part of you. Your heart rules over your entire body, if it is upright then your whole body will be upright, and vice versa.
For the sake of Allah, protect it dearly and don’t allow your eyes and ears to fall on something that will corrupt your heart.
رَبَّنَا لَا تُزِغْ قُلُوبَنَا بَعْدَ إِذْ هَدَيْتَنَا وَهَبْ لَنَا مِنْ لَدُنْكَ رَحْمَةً
﴿٨ آل عمران﴾
“Our Lord, let not our hearts deviate after You have guided us and grant us from Yourself mercy. Indeed, You are the Bestower.”
Surah Aale Imran 8
