Sahih al-Bukhari #1Sincerity & IntentionSAHIHSAHIH
إِنَّمَا الْأَعْمَالُ بِالنِّيَّاتِ، وَإِنَّمَا لِكُلِّ امْرِئٍ مَا نَوَى، فَمَنْ كَانَتْ هِجْرَتُهُ إِلَى دُنْيَا يُصِيبُهَا أَوْ إِلَى امْرَأَةٍ يَنْكِحُهَا فَهِجْرَتُهُ إِلَى مَا هَاجَرَ إِلَيْهِ
Actions are judged by intentions, and every person shall have what they intended. So whoever emigrated for worldly benefits or to marry a woman, then their emigration is for what they emigrated for.
