With respect

1. What is the opinion of Allamah about the Muslims’ wars after the Prophet?

2. Is the Caliphs’ proceeds in war makings, which accidentally has led to extension of Islam, acceptable?

3. Does the law of murder, which is mentioned in Qur’an, mean attack, rape and exterminating?

 The answer of your questions are as follow order:

1. The claim that Islam was introduced to the world by sword is not a valid claim; because Islam, first of all, was introduced to the world by the letters that the Messenger of God (peace be upon him), after treaty of Hudaybiyyah, wrote for the world’s kings, and by that means called them toward submission to God. After the Messenger of God (peace be upon him) also Muslims, by leaning on their sword’s power, did not prevail over Iran and Rome; since their sword’s power was not greater than the sword’s power of those superpowers, and naturally could not lead them to prevail over Kasra and Kaiser lonely. Therefore, it is fair that the most important factor of the influence, survival and extension of Islam in different countries is its attractive, exquisite and man-constructor teachings which still lead to its influence, survival and extension in different countries, as his honor Allamah Mansoor Hashemi Khorasani (may God protect him), in the issue of “The right way of confronting unbelievers” from the noble book “Return to Islam”[1] , mentioned to this important point and has said:

“Muslims’ dominance during the primary Islamic decades over the western and eastern emperors, was not due to their developed propaganda or even military means, but it was only the charisma in their message that was able to make the glitters of the world emperors lose favor among people and paved the way for their political and military developments, despite their limited facilities”.

With this description, it seems that the claim of Islam's influence, survival, and extension in different countries by leaning on the sword is an apparent exaggeration and unfairness that is derived solely from anti-Islamists inducements. Of course, there is no doubt that Muslims, after the Messenger of God (peace be upon him), had wars in different countries, but these wars were not typically with the people of those countries, but were with their unbeliever and oppressive rulers who have often dominated those regions through war and tried to oppress the peasantry, and with this description the Muslims’ wars must be regarded as the aim of liberating these regions from the occupation of unbelievers and oppressors; As for instance,  from  Rabi'i ibn Amer, the representative of Muslims in Qadisiyyah war for having conversation with Rostam Farrokhzad the commander of Iran’s army, is quoted that in response to his question about Muslims’ propensity for having war with them, said: “God has aroused us and God has brought us to take out whoever He wills from the slavery of men to the slavery of God and from the poverty of the world to its ample and from the oppression of religions to justice of Islam, and sent us with His religion until we call his people toward Him, then whoever accepts it, we accept from him and come back from him, and leave him with his land to govern it by himself”[2], and this is in accordance with the special worldview of Islam that knows earth for the God, and do not recognize ownership of men over it officially and says: ﴿إِنَّ الْأَرْضَ لِلَّهِ يُورِثُهَا مَنْ يَشَاءُ مِنْ عِبَادِهِ ۖ وَالْعَاقِبَةُ لِلْمُتَّقِينَ﴾[3]; “Indeed earth is for God, He bestows it to any one of His servants He wills and the future eventually belongs to the pious people”.

2. According to the basis of Allamah Mansoor Hashmi Khorasani (may God protect him) in the noble book “Return to Islam”[4], launching the war is permissible only with the permission of the God’s Caliph on earth, but it seems that such a permission, for Muslims’ wars with non-Muslims, after The Messenger of God (peace be upon him), has been existed implicitly at least during the time of Abu Bakr, Umar and Uthman; because there is no clear and proved opposition, narrated from the Ahl al-Bayt of The Messenger of God (peace be upon him) to these wars -even during the time of sovereignty of Ali and Hassan- but numerous supports and collaborations have been narrated in this regard, in which it can be mentioned among them to: Ali's with Omar consultation about the battle of al-Jisr, the conquest of Nahavand, the war with the Romans, the conquest of Jerusalem, the conquest of Khorasan and the conquest of Susa; regardless of that their possession of the trophies and slaves of these wars is certain and can imply to their belief in legitimacy of these wars, implicitly.

3. God's command to fight with the unbelievers and the oppressors is destroying the infidelity and oppression and saving the oppressed people of the world, not looting, raping, and exterminating, as He has said: ﴿وَقَاتِلُوهُمْ حَتَّى لَا تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ لِلَّهِ ۖ فَإِنِ انْتَهَوْا فَلَا عُدْوَانَ إِلَّا عَلَى الظَّالِمِينَ﴾[5]; “Fight them until faithlessness is no more, and religion becomes [exclusively] for Allah. Then if they relinquish, there shall be no reprisal except against the wrongdoers”; because God does not need looting, raping and exterminating, but He does not tolerate infidelity and oppression in the world, as He has said: ﴿إِنْ تَكْفُرُوا فَإِنَّ اللَّهَ غَنِيٌّ عَنْكُمْ ۖ وَلَا يَرْضَى لِعِبَادِهِ الْكُفْرَ ۖ﴾[6]; “If you disbelieve, undoubtedly God does not need you, while He is not satisfied with blasphemy”, and He has said: ﴿وَمَا اللَّهُ يُرِيدُ ظُلْمًا لِلْعَالَمِينَ﴾[7]; “And God does not like any oppression for the people of the world!”.

It is strange that the unbelievers and the oppressors, always throughout their history, have fought against the world's oppressed people for the purpose of globalizing infidelity and oppression, and have refrained from no exterminating, raping or looting, but the Muslims’ wars with the aim of globalizing monotheism and justice and saving oppressed people of the world is considered as inadmissible and an example of looting, raping and exterminating! Undoubtedly, this is an evil conspiracy from them for dominating Taughut’s over the world, as God has said: ﴿الَّذِينَ آمَنُوا يُقَاتِلُونَ فِي سَبِيلِ اللَّهِ ۖ وَالَّذِينَ كَفَرُوا يُقَاتِلُونَ فِي سَبِيلِ الطَّاغُوتِ فَقَاتِلُوا أَوْلِيَاءَ الشَّيْطَانِ ۖ إِنَّ كَيْدَ الشَّيْطَانِ كَانَ ضَعِيفًا﴾[8]; “Those who believed in, fight in the way of God and those who became infidels, fight in the way of Taughut, therefore fight against friends of Satan that Satan’s deception is weak”!
