Question: Who was appointed arbitrator by the first convert to the faith that is the most common religion in Southeast Asia?

<P0-S0> in 1893, the city of chicago hosted the world columbian exposition, an early world's fair. <P0-S1> so many people were coming to chicago from all over the world that many smaller conferences, called congresses and parliaments, were scheduled to take advantage of this unprecedented gathering. <P0-S2> one of these was the world's parliament of religions, an initiative of the swedenborgian layman (and judge) charles carroll bonney. <P0-S3> the parliament of religions was by far the largest of the congresses held in conjunction with the exposition. <P0-S4> john henry barrows, a clergyman, was appointed as the first chairman of the general committee of the 1893 parliament by charles bonney. <SEP> <P1-S0> Country Population Christian Islam Irreligion Hindu Buddhist Folk religion Other religion Jewish Pop.% Pop.% Pop.% Pop.% Pop.% Pop.% Pop.% Pop.% Brunei 400,000 37,600 9.40 300,400 75.10 1,600 0.40 1,200 0.30 34,400 8.60 24,800 6.20 400 0.10 0 0.00 Burma 47,960,000 3,740,880 7.80 1,918,400 4.00 239,800 0.50 815,320 1.70 38,415,960 80.10 2,781,680 5.80 95,920 0.20 0 0.00 Cambodia 14,140,000 56,560 0.40 282,800 2.00 28,280 0.20 0 0.00 13,701,660 96.90 84,840 0.60 0 0.00 0 0.00 Indonesia 239,870,000 23,747,130 9.90 209,166,640 87.20 240,000 0.10 4,077,790 1.70 1,679,090 0.70 719,610 0.30 239,870 0.10 0 0.00 Laos 6,200,000 93,000 1.50 0 0.00 55,800 0.90 0 0.00 4,092,000 66.00 1,903,400 30.70 43,400 0.70 0 0.00 Malaysia 28,400,000 2,669,600 9.40 18,090,800 63.70 198,800 0.70 1,704,000 6.00 5,026,800 17.70 653,200 2.30 56,800 0.20 0 0.00 Philippines 105,000,000 89,000,000 85.00 5,127,000 5.50 7,350,000 7.00 10,000 0.00 1,758,000 1.50 1,398,900 1.50 93,260 0.10 28,473 0.03 Singapore 5,090,000 926,380 18.20 727,870 14.30 834,760 16.40 264,680 5.20 1,725,510 33.90 117,070 2.30 493,730 9.70 0 0.00 Thailand 69,120,000 622,080 0.90 3,801,600 5.50 207,360 0.30 69,120 0.10 64,419,840 93.20 60,000 0.09 0 0.00 0 0.00 Timor - Leste 1,120,000 1,115,520 99.60 1,120 0.10 0 0.00 0 0.00 0 0.00 1,120 0.10 0 0.00 0 0.00 Vietnam 94,700,000 7,765,400 8.20 175,700 0.20 28,031,200 29.60 151,200 0.16 15,530,800 16.40 42,899,100 45.30 351,400 0.40 0 0.00 Total 593,410,000 116,571,210 21.33 245,594,630 40.38 31,903,260 4.70 6,932,110 1.17 143,582,660 24.20 47,540,670 8.01 1,374,780 0.23 28,437 0.00 <SEP> <P2-S0> One account in Tabari says that the first male convert is Zayd ibn Harithah, a freed slave who had become Muhammad's adopted son. <P2-S1> It is known that Ali is the first person to convert to Islam, however some dispute this arguing he was only 12 years old at the time he embraced Islam. <SEP> <P3-S0> Following this battle, Ali fought a battle against Muawiyah, known as the Battle of Siffin. <P3-S1> The battle was stopped before either side had achieved victory, and the two parties agreed to arbitrate their dispute. <P3-S2> Seven months later, in February 658, the two arbitrators met at Adhruh, about 10 miles north west of Maan in Jordon. <P3-S3> Amr ibn al-As convinced Abu Musa Ashaari that both Ali and Muawiyah should step down and a new Caliph be elected. <P3-S4> Ali and his supporters were stunned by the decision which had lowered the Caliph to the status of the rebellious Muawiyah I. Ali was therefore outwitted by Muawiyah and Amr. <P3-S5> Ali refused to accept the verdict and found himself technically in breach of his pledge to abide by the arbitration. <P3-S6> This put Ali in a weak position even amongst his own supporters. <P3-S7> The most vociferous opponents in Ali's camp were the very same people who had forced Ali into the ceasefire. <P3-S8> They broke away from Ali's force, rallying under the slogan, "arbitration belongs to God alone." <P3-S9> This group came to be known as the Kharijites ("those who leave"). <P3-S10> In 659 Ali's forces and the Kharijites met in the Battle of Nahrawan. <P3-S11> Although Ali won the battle, the constant conflict had begun to affect his standing, and in the following years some Syrians seem to have acclaimed Muawiyah as a rival caliph. <P3-S12> After the battle Amr ibn al-As was appointed by Muawiyah as an arbitrator, and Ali appointed Abu Musa Ashaari. <SEP> <P4-S0> there are several theories to the islamisation process in southeast asia. <P4-S1> another theory is trade. <P4-S2> the expansion of trade among west asia, india and southeast asia helped the spread of the religion as muslim traders from southern yemen (hadramout) brought islam to the region with their large volume of trade. <P4-S3> many settled in indonesia, singapore, and malaysia. <P4-S4> this is evident in the arab-indonesian, arab-singaporean, and arab-malay populations who were at one time very prominent in each of their countries. <P4-S5> the second theory is the role of missionaries or sufis. <P4-S6> [citation needed] the sufi missionaries played a significant role in spreading the faith by introducing islamic ideas to the region. <P4-S7> finally, the ruling classes embraced islam and that further aided the permeation of the religion throughout the region. <P4-S8> the ruler of the region's most important port, malacca sultanate, embraced islam in the 15th century, heralding a period of accelerated conversion of islam throughout the region as islam provided a positive force among the ruling and trading classes.
