According to a hadith, the first three people whom Allah will call to send them to hell will be a scholar, a martyr, and a wealthy man. The hadith is as follows:
The Martyr:
On the authority of Abu Hurayrah (may Allah be pleased with him), who said: I heard the Messenger of Allah (PBUH) say:
The first of people against whom judgment will be pronounced on the Day of Resurrection will be a man who died a martyr. He will be brought and Allah will make known to him His favors and he will recognize them. [ The Almighty] will say: And what did you do about them? He will say: I fought for you until I died a martyr. He will say: You have lied – you did but fight that it might be said [of you]: He is courageous. And so it was said. Then he will be ordered to be dragged along on his face until he is cast into Hell-fire.
The Scholar or Qari:
[Another] will be a man who has studied [religious] knowledge and has taught it and who used to recite the Quran. He will be brought and Allah will make known to him His favors and he will recognize them. [The Almighty] will say: And what did you do about them? He will say: I studied [religious] knowledge and I taught it and I recited the Quran for Your sake. He will say: You have lied – you did but study [religious] knowledge that it might be said [of you]: He is learned. And you recited the Quran that it might be said [of you]: He is a reciter. And so it was said. Then he will be ordered to be dragged along on his face until he is cast into Hell-fire.
The Richman:
[Another] will be a man whom Allah had made rich and to whom He had given all kinds of wealth. He will be brought and Allah will make known to him His favors and he will recognize them. [The Almighty] will say: And what did you do about them? He will say: I left no path [untrodden] in which You like money to be spent without spending in it for Your sake. He will say: You have lied – you did but do so that it might be said [of you]: He is open-handed. And so it was said. Then he will be ordered to be dragged along on his face until he is cast into Hell-fire.
