You are doing things that appear, in your eyes, finer than a hair, yet during the time of the Messenger of Allah ﷺ we used to count them among the destructive sins.
حدثنا عبد الملك بن عمرو حدثنا عباد يعني ابن راشد عن داود بن أبي هند عن أبي نضرة
إنكم لتعملون أعمالا هي أدق في أعينكم من الشعر كنا نعدها على عهد رسول الله ﷺ من الموبقات
Its isnad is sahih. Ammar bin Rashid is a mistake, its correct form is Abbad bin Rashid, as in 10942, because the narrator is the same person, and he is trustworthy. Bukhari narrated the hadith, 11/329, number 6492 [Fath], in the Book of Raqaiq, chapter on being wary of minor sins, from Anas. This hadith is a warning to everyone who belittles small deeds and the sins they assume Allah will not hold them accountable for.
