There are differences but we should accept them
"And lest your power depart." [The Holy Quran, 8: 46] What is the meaning of this? This verse exactly reflects our current situation. When there is discord, when we are suspicious of one another, and when we consider one another as traitors, we will naturally avoid cooperation. Even if we do cooperate with one another, we will not be sincere. That is exactly what the enemy is after. Both Shia and Sunni scholars must understand this. It is quite natural for two denominations of a religion to have differences in some of their primary and secondary principles. Of course they are normally similar in the majority of their principles. But difference is not the same as hostility. In some cases, the fatwas that are issued by Shia muftis are radically different. Similarly, the fatwas issued by Sunni muftis are sometimes very different from one another. But when there is difference, one should not necessarily engage in insulting and slandering. We should accept the differences.That is to say, no particular denomination should think that the members of the Prophet's household belong to them. That is not the case: They belong to the world of Islam. Is there anyone who cannot accept Fatima Zahra (a.s.)? Is there anyone who cannot accept Imam Hussein (a.s.), the master of those who live in Paradise? Is there anyone who cannot accept the honorable Shia Imams? Shia Imams may be considered a religious leader by some, and some others believe that it is not obligatory to obey them, but all Muslims accept them. These are the facts, and we must understand and institutionalize them. Of course there are some people who do not understand these things. They give in to the enemy's provocations, while they think they are doing the right thing.
