The Book of the Believer · Hadith 29 (#Ḥadīth #29)
Chapter 1 | The Severity of a Believer’s Afflictions
29 - وعنه (ع) قال ما فَلتَ المؤمنُ من واحدةٍ من ثلاث، أو جمِعتْ عليه الثلاثةُ: أن يكون معه مَن يغلق عليه بابَه في داره، أو جارٍ يؤذيه أو مَن في طريقه إلى حوائجه يؤذيه، ولوأنّ مؤمناً على قلّة جبلٍ لبعث الله شيطاناً يؤذيه، ويجعل الله له من إيمانه أنساً.
29. It has been also narrated that Abu 'Abd Allah said: A believer never escapes one of three (problems) if not all three! Either a family member who shuts him out, or a neighbor who troubles him, or a person he meets on his way to work (who troubles him). Even if a believer were (to isolate himself) on a mountain top, Allah would send a devil to bother him. And Allah provides for him (the believer) comfort from his faith.”
