"There are five things that corrupt the heart:

1️⃣ Excessive socializing/mixing with people;

2️⃣ Constantly indulging in overeating (filling the stomach);

3️⃣ Excessive sleep;

4️⃣ Strengthening attachments to others besides Allah;

5️⃣ Worldly desires/aspirations!"

Imam Ibn al-Qayyim (Rahimahullah)

(Madarij al-Salikin: 1/451)
