Hadith.3749 - It is narrated from Ishaq ibn Ammar who said:
I said to Abu Abdillah (as), "I receive dirhams from a man, weigh them, then distribute them, and a surplus remains in my hand. What should I do?"
Imam (as) said: "Did you not strive to be accurate in your measure?"
I said: "Yes."
Imam (as) said: "Then there is no harm."
