Hadith 31-334

وَبِهذَا الإسناد قالَ: قالَ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَآلِهِ: يوحى اللَّه عَزَّ وَجَلَّ إِلى الحفظة الكرام البررة لا تكتبوا عَلَى عَبْدِي وَاُمَّتِي ضجرهم وَعثرتهم بَعْد العصر.

According to the same documentation, God’s Prophet (S) said, “The Honorable the Exalted God revealed to the ‘al-Kiram al-Barara’ who are the guardian angels appointed for man, not to record any slippages of My servants after they say their afternoon prayers.”
