Professor Ansarian said: you should not be skeptical toward anyone. Every day, we hear people talking behind others back, or we hear something about some special people on the phone, we have not witnessed what we hear, or they have not occurred before our very eyes. we should not believe them. The holy Quran says:
“وَلَا تَقْفُ مَا لَيْسَ لَكَ بِهِ عِلْمٌ إِنَّ السَّمْعَ وَالْبَصَرَ وَالْفُؤَادَ كُلُّ أُولَئِكَ كَانَ عَنْهُ مَسْئُولًا”
Do not follow what you do not know; the ears, eyes, and hearts will all be held responsible for their deeds. (Surah Al-Isra-36)
in other words, try not to believe what you have not seen with your own two eyes.
