Abu Dawud Book 14, Hadith Number 3084.

Narated By Muhammad ibn Khalid as-Sulami : As-Sulami’s grandfather, who was a Companion of the Apostle of Allah (PBUH) said: I heard the Apostle of Allah (PBUH) say: When Allah has previously decreed for a servant a rank which he has not attained by his action, He afflicts him in his body, or his property or his children.
