Doing good to impress others will lead one to Hell-fire

On the authority of Abu Hurayrah Radhiyallahu anh, who said: I heard the Messenger of Allah Sallallahu alihi wassalam 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 favours 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. [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 his His favours 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. [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 his His favours 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.
It was related by Muslim (also by at-Tirmidhi and an-Nasa'i). This is a Hadeeth Qudsi. (A Sacred Hadith is, as to the meaning, from Allah the Almighty; as to the wording, it is from the messenger of Allah (PBUH). It is that which Allah the Almighty has communicated to His Prophet through revelation or in dream, and he, peace be upon him, has communicated it in his own words. Thus Qur'an is superior to it because, besides being revealed, it is Allah SWT's wording.)

Oh Allah, keep my intentions and worship always pure and solely to please You, and nobody else. Protect me, Ya Allah, from the above the group of people, aameen...

- The martyr who died so that people will say he is courageous.
- The learned (who was very learned in religious studies)who wants people to say of him, "he is learned".
- The Qur'an reciter who wishes for people to say: He is a reciter.
- The one who spent his wealth in charity so that people will say: He is very open-handed.
