Sahih al-Bukhari 6953
Narrated `Umar bin Al-Khattab:
The Prophet (ﷺ) said, 'O people! The reward of deeds depends upon the intentions, and every person will 
get the reward according to what he has intended. So, whoever emigrated for Allah and His Apostle, 
then his emigration was for Allah and His Apostle, and whoever emigrated to take worldly benefit or 
for a woman to marry, then his emigration was for what he emigrated for."
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ بْنِ وَقَّاصٍ، قَالَ سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ ـ رضى الله عنه ـ يَخْطُبُ قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏
"‏ يَا أَيُّهَا النَّاسُ إِنَّمَا الأَعْمَالُ بِالنِّيَّةِ وَإِنَّمَا لاِمْرِئٍ مَا نَوَى، فَمَنْ كَانَتْ هِجْرَتُهُ إِلَى اللَّهِ وَرَسُولِهِ، فَهِجْرَتُهُ إِلَى اللَّهِ وَرَسُولِهِ، وَمَنْ هَاجَرَ إِلَى دُنْيَا يُصِيبُهَا أَوِ امْرَأَةٍ يَتَزَوَّجُهَا، فَهِجْرَتُهُ إِلَى مَا هَاجَرَ إِلَيْهِ ‏"‏‏.‏
