The Grocer & The Satan: Sufi Story by Shaykh Saadi
Shaykh Saadi narrates story of a grocer, who spent entire day lying to customers, deceit and corruption in weighing things.
However, when he ended the business every day, he loudly cursed Satan for mischief.
One day Shaitaan got annoyed and retorted to him:”You spend your whole day listening to my advice and doing mischief & corruption, but when you finish business, you start cursing on me. Which sides you are anyways?!”
