assalamu 'alaykum brother Muhammad Raza from India, Answer 1) There is a difference between 'alauddin and his empire, and the people living in the empire. When Genghis Khan attacked his empire, he killed the innocent people as well. No one knows how many murids of Sayyidna Najmuddin Kubra raDiyaAllahu 'anhu were martyred. It is a fact that thousands of Sufis in Urgench (northern Uzbekistan) where, so many of the Kubrawi murids were stationed, actively engaged in jihad against the invading Mongols. Sayyidna Najmuddin Kubra himself was martyred by the Mongols in Khawarizm/Urgench itself. So, I do not believe that Sayyidina Najmuddin wished for the empire to get destroyed, because he and all other Sunnis were themselves living in the empire and they did jihad against the Mongols. But it is possible he made bad du'a for 'alauddin. Answer 2) We do not know exactly how the caravan got ravaged. It is commonly stated that Khawarizm Shah ravaged that caravan. This is possible, but what are the scenarios on the ground at that time, the contexts, and conditions. If Khawarizm Shah did it out of pride and power, then it was indeed very stupid of him. Islamically, I do not know, we would have to examine the details around this incident in detail. However, we do know that we do not kill the guests who come to our lands, but we serve them hospitality instead. There are other possibilities too, such as some other enemies of Islam and Muslims doing it, and spreading the wrong propaganda around. As you know, the crusaders had spies all around. They knew about the Khawarizmis. Much later, the displaced Khawrizmi army itself ravaged some of the crusaders in the Levant. These are just theories mixed with some facts. We would need to do proper research here from the primary sources, such as Ibn Athir's manuscripts. Answer 3) As you know, the Seljuqs were then just fighting among themselves everywhere from Aleppo all the way to Khurasan and Caucasus. The ones in Khurasan just bribed the Khawarizmi governers to support them to fight the other Seljuqs. All Khawarizmis, all Seljuqs were Mamluk Turks, Khurasan/Iran dwellers. They were both from the central asian turkish tribes, mamluk tribes. They were all Sunni, but fought eachother for power, control, and land like Sunnis nowadays. The enmity between them was for power, control, and land. The Khawarizmis included fresh, strong Turks from the hinterland. Seljuqs were already almost entirely assimilated into local populations.
