I am just saying we should not wish a bad afterlife on anyone. No one hates Islamism more then me, but any beef we have is only within context of this world.
Brother, these people are zalims, and zalims are people of hell. A person to whom message of Islam has reached, and they know Islam, still believe and preach Kufur like suicide and killing of innocents, and spread fitna in this world by killing and creating mayhem, their end has to be in hell.
The intercession of our Prophet, the Master of all creations, is for all who have iman. We can hate the actions of these guys, but do have any doubt that so long as he died on iman, he may benefit from the glory of our Prophet's infinite capacity to love and seek forgiveness for the ummah who follow them is, atleast to my mind, a bigger concern on the galactic scale.
There is no doubt about intercession of Prophet (SAW). Anyhow, I think that many Muslims have misunderstood the condition of intercession. Just like Brahmans think that they are next to God, Jews think that they are chosen people, and Christians think that mere believe on Jesus would give them salvation, Shaitan in similar way has made some Muslims believe that just because they are Muslim, Prophet (SAW) would do intercession for them and they would go to heaven.
On the other hand, Prophet (SAW) is most close to Allah than any of his creations, and would not do anything that Allah may not like. Allah has clearly said in Quran that intercession would be with permission and no doubt that Prophet (SAW) would have unrestrictive permission, thus if he would intercede for anyone, they would get forgiven and their victims would get compensated by Allah. So, obviously Prophet (SAW) would not intercede for Zalims and Fitna creators.
Allah has promised his creation that he would do justice to all on judgment day. That means, all who are harmed would get their revenge, unless they themselves forgive or are justly compensated. No Muslim does any favour on Prophet (SAW) by being Muslim, as religion Islam is not religion of Prophet (SAW) but religion of Allah, and Prophet (SAW) was a messenger of Allah. So, doing intercession for people Prophet (SAW) do not have any personal relation other than they believe on him as Prophet would be ridiculous.
Thus, Prophet (SAW) would do intercession for only those who are close to him with his person. Such people could be close because they are from his own blood, and others who may not be from his blood but have developed relationship of spiritual closeness with Prophet (SAW). That is why many pious Muslims try to develop that spiritual relationship with Prophet (SAW) by their immense love and respect, and sending darud and salaam on Prophet (SAW) vigorously and regularly, so that they qualify for that intercession. These people also make sure that they do not harm creation of Allah intentionally and unnecessarily, as those who harm other creations of Allah intentionally and unnecessarily are Zalims and Zalim could never develop any spiritual relationship with Prophet (SAW), as person (Zaat) of Prophet (SAW) was Rahmat, who oppose all sort of Zulum and Fitna.
