اعمال کے اجر وثواب کا دارومدار نیت پر ہے

Abu Hurayrah (may Allah be pleased with him) narrated that he heard the Messenger of Allah (peace be upon him) say: "On the Day of Resurrection the first to be brought forward will be a man who was martyred. Allah will remind him of His favours and he will acknowledge them. Allah will ask him, 'What did you do to fulfil their due?' He will say, 'I fought for Your sake until I was martyred.' Allah will say, 'You have lied. You fought only so that it might be said you were brave, and so it was said in the world.' Then the order will be given and he will be dragged on his face and cast into the Fire. Next a man will be brought who had learned knowledge and taught it and had recited the Qur'an. Allah will remind him of His favours and he (the scholar) will acknowledge them. Then Allah will ask, 'What did you do to give thanks for these favours?' He will say, 'O Allah, I acquired knowledge and taught it to people, and I recited the Qur'an to people for Your sake.' Allah will say, 'You have lied. You learned so that it might be said you were a scholar, and you recited the Qur'an so that it might be said you were a reciter, and so the world called you a scholar and a reciter.' Then the order will be given and he will be dragged on his face and cast into the Fire. Then a third man will be brought whom Allah had given ample means and every kind of wealth in the world. Allah will remind him of His favours and he will acknowledge them. Then Allah will ask, 'Having received My favours, what did you do?' He will say, 'O Allah, I spent wealth for Your sake in every cause in which You love it to be spent.' Allah will say, 'You have lied. You spent only so that it might be said you were generous, and the world called you generous.' Then the order will be given and he will be dragged on his face and cast into the Fire." (Muslim)

The acceptance or rejection of all deeds before Allah depends solely on sincerity of intention: that is, only those good deeds performed purely for the pleasure and approval of Allah will hold any worth in His sight. In contrast, however righteous and sound a deed may outwardly appear, if it contains the least trace of showing off, display or ostentation, then not only will that deed have no value, it will itself become a cause of the Fire.
