Narrated Muhammad ibn Khalid as-Sulami:
on his father's authority said his grandfather reported: He was a Companion of the Messenger of Allah (ﷺ) said: I heard the Messenger of Allah (ﷺ) 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.
Abu Dawud said: Ibn Nufail added in his version: "He then enables him to endure that." The agreed version goes: "So that He may bring him to the rank previously decreed from him by Allah."
