"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)
