Furthermore, one thing we must know is that Imam Ali (as) did not call to himseld because he did not want the people to apostate. So what Imam Ali (as) actually did PROTECTED Islam.
Salam,
Brother PLEASE try to ponder and reflect on your statement. If `Ali did not preach the message, then what applies to him applies to the Prophet (saw): {O Messenger (Muhammad SAW)! Proclaim (the Message) which has been sent down to you from your Lord. And if you do not, then you have not conveyed His Message.}
`Ali's job acc to you folks IS TO GUIDE, he never did. Why would the Prophet (saw) be commanded to proclaim the message and get a guarantee of protection then the leader right after him hides that same message and never proclaims it?
Secondly, your words "`Ali did not call to him in order to PROTECT ISLAM" This means that the belief in divine infallible leaders is not necessary for having faith.
If the so called Imamah was necessary for Islam, then it needed to be preached for Islam to be "protected". However, not announcing it to "protect Islam" says a lot about this irrational belief.
Just ponder on this and don't repeat the arguments of the Shia leaders without thought.
Please ponder on the comparison with Prophet Harun (as).
[Moses] said, "O Aaron, what prevented you, when you saw them going astray, From following me? Then have you disobeyed my order?"
[Aaron] said, "O son of my mother, do not seize [me] by my beard or by my head. Indeed, I feared that you would say, 'You caused division among the Children of Israel, and you did not observe [or await] my word.' "
Imam Ali (as) - yes, he is a guide. But by calling to himself he would be doing the opposite of guiding, because according to the hadith people might become kafirs due to this. So by you saying "well he should have just guided people" - this may result in people rejected the shahada and Islam in general, thereby doing the complete opposite.
Firstly, Hujjah cannot be established on assumptions, and this contradicts the obligatory principle of Amr bil maroof wa nahi anil munkar(Enjoining good & forbidding evil). Imagine Prophet(saw) assuming that Abu Jahl will never accept his prophethood so he doesn’t gives him the Message, this would sound irrational and nonsense, because hujjah cannot be established based on assumptions. And regarding forbidding the wrong we read in Shia hadeeth that:
The messenger of Allah(saw) said: Allah bears grudge (dislikeness) for the “WEAK BELIEVER”, who doesn’t have any religion(Deen). It is asked: Who will be believer who doesn’t have any religion? Prophet(saw) said: The one who doesn’t fulfill the obligation of “Forbidding Wrong”. (Furu’al Kafi Vol. 5 Page. 59).
Shias try to counter these points by bringing up the incident of Prophet Harun(as), when Prophet Musa(as) left him with the people, and those people started worshiping a calf and didn’t listen to Harun(as). However this issue is a proof against Shia, because Harun(as) did indeed try to forbid those people from wrong and evil,
to the extent that they were about to kill him. This proves that he was not only forbidding them from tongue but also protesting them as much as he could. This is evidenced in the following verses of Quran:
And
Hârûn (Aaron) indeed had said to them beforehand: “O my people! You are being tried in this, and verily, your Lord is (Allâh) the Most Beneficent, so follow me and obey my order.” They said: “We will not stop worshipping it (i.e. the calf), until Mûsa (Moses) returns to us.” (Quran 20:90-91)
When Musa returned to his people, angry and sad, he said, .How bad is the thing you have done in my absence! How did you act in haste against the command of your Lord?. He dropped down the Tablets, and grabbed the head of his brother, pulling him towards himself.
He (Harun) said, .My mother‘s son, the people took me as weak and were about to kill me. So do not let the enemies laugh at me, and do not count me with the wrong-doers.(Quran 7:150).
Harun(as) didn’t just assume that people will disobey him, so he needs to be silent, on the contrary Harun(as) tried hard to forbid those people from wrong and evil and invited them towards good, to the extent that they were about to kill him, as they overpowered him and found him weak.
