Don't give a very direct look to the old books, I suppose hafizz dahabi didn't have tv, mobile, radio... Who knows what kinda of sins were there back in his age? Did the prophet gave his own tafsir on the quran? If yes why all these tafsir books? The slightest thing in our age comparing to their age could be interpreted as a kabair because they had less ways who can help to facilitate the sins coming into their lives.
Use your reason and tray to figure out instead of taking examples from the ancient lives
This is how I figure out.viewtopic.php?f=13&t=308446
