A life full of sins = a world full of sickness.

بـسـم الله والحـمـد لله والـصلاة والـسـلام عــلى رسـول الله، وبـعـد

Ibn al-Qayyim رحمه الله said: “As a whole, whoever sins, then sins remove away the blessings from the Deen and the Dunyaa, so that he won’t find any blessings in his age [1], his religious affairs [2] and his worldly affairs [3].” [al-Jawaab al-Kaafi (1/84)]

[1] Life full of suffering and illnesses.
[2] Less good deeds.
[3] A person may have much wealth, but he may have a problem with his wife, children or the society abhors him etc.

We ask Allah for our well being.
