كتاب الحيل
Read the English translation first, with the original Arabic directly underneath.
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 Messenger, then his emigration was for Allah and His Messenger, and whoever emigrated to take worldly benefit or for a woman to marry, then his emigration was for what he emigrated for."
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
