On the authority of Omar bin Al-Khattab, who said : I heard the messenger of Allah Sallallahu Alaihi Wasallam say : “Actions are but by intention and every man shall have but that which he intended. Thus he whose migration was for Allah and His messenger, his migration was for Allah and His messenger, and he whose migration was to achieve some worldly benefit or to take some woman in marriage, his migration was for that for which he migrated.” ~ Related by Bukhari and Muslim

One of the question in the dialogue between Rasulullah SAW and Iblees:
Rasulullah SAW asked: “Who do you like?”

Iblees replied: “People who relieve your syariat and hate people who learn Islam”.

عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللهُ عَنْهُمَـا ، عَنْ رَسُوْلِ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِيْمَـا يَرْوِيْهِ عَنْ رَبِّهِ تَبَارَكَ وَتَعَالَى ، قَالَ : «إِنَّ اللهَ كَتَبَ الْـحَسَنَاتِ وَالسَّيِّـئَاتِ ، ثُمَّ بَيَّنَ ذَلِكَ ، فَمَنْ هَمَّ بِحَسَنَةٍ فَلَمْ يَعْمَلْهَا ، كَتَبَهَا اللهُ عِنْدَهُ حَسَنَةً كَامِلَةً ، وَإِنْ هَمَّ بِـهَا فَعَمِلَهَا كَتَبَهُ اللّـهُ عَزَّوَجَلَّ عِنْدَهُ عَشْرَ حَسَنَاتٍ إِلَى سَبْعِمِائَةِ ضِعْفٍ إِلَى أَضْعَافٍ كَثِيْرَةٍ ، وَإِنْ هَمَّ بِسَيِّـئَةٍ فَلَمْ يَعْمَلْهَا ؛ كَتَبَهَا اللهُ عِنْدَهُ حَسَنَةً كَامِلَةً ، وَإِنْ هَمَّ بِهَـا فَعَمِلَهَا ، كَتَبَهَا اللهُ سَيِّئَةً وَاحِدَةً ». رَوَاهُ الْـبُخَارِيُّ وَمُسْلِمٌ فِـيْ صَحِيْحَيْهِمَـا بِهَذِهِ الْـحُرُوْفِ

From Ibn ‘Abbas radi’ anhu from the Prophet sallallaahu ‘alaihi wa sallam about the hadith which he narrates from his Lord Almighty. The Prophet sallallaahu ‘alaihi wa sallam said, “Verily, Allah writes the virtues and faults and then explain it. Whoever intends to do good but he is not do it, Allah will write it as one full goodness his side. If he intends to do good then do it, then Allah write on his side as ten to seven hundred times to many multiples of his goodness. Whoever intends to do bad, but he did not do it, then Allah wrote it in his hand as one goodness. And he intends to make mistakes and then do it, then Allah wrote it as a big as the mistake he did. “[HR. al-Bukhari and Muslim in their Shahiih book – al-Bukhâri (no. 6491), Muslim (no. 131 [207]) dan Ahmad (I/310, 361).]
