Ayatollah Mohammad Hassan Zali (Fazel Golpaygani), an Iranian thinker, has stressed that differences in faith should not result in conflict and clashes.

Ayatollah Mohammad Hassan Zali noted, "Difference in faith should not result in conflict and clashes. Difference in faith should not result in desecration of sanctities, violation of rules, and lack of piety, while observing orders of God Almighty and Prophet Muhammad (PBUH)."

"Holy Quran cautions against any tough behavior, bad-temperedness, cursing and insult. Holy Quran says, “Verily, this Qur'an guides to that which is most just and right.”

The thinker stated, "Holy Quran advises us to speak with people in a good way, and eloquently and lead peaceful co-existence. There is not enough time to refer to the Holy Quran’s verses as far as the audience are all well informed of Holy Quran."

Ayatollah Zali underlined that Prophet Muhammad (PBUH) should be a model for Muslims because he is a beautiful model. The Prophet Muhammad (PBUH) was not a person to be bad-tempered. Holy Quran says, “It was thanks to Allah's mercy that you were gentle to them.”
