Ibn al-Qayyim رحمه الله said, these four things draw and attract sustenance: 1. Tahajjud 2. Abundant istighfār before Fajr 3. Consistent charity 4. Dhikr in the morning and evening. And these four prevent rizq (sustenance): 1. Sleeping in the morning 2. Laziness 3. Few optional prayers 4. Betrayal of trust. 📑: Zad al-Ma'aad, vol. 4 | p. 378.
