The value of Intention in Islam

﷽

عَنْ عُمَرَ بْنِ الْخَطَّابِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّمَا الْأَعْمَالُ بِالنِّيَّةِ وَإِنَّمَا لِامْرِئٍ مَا نَوَی فَمَنْ کَانَتْ هِجْرَتُهُ إِلَی اللَّهِ وَرَسُولِهِ فَهِجْرَتُهُ إِلَی اللَّهِ وَرَسُولِهِ وَمَنْ کَانَتْ هِجْرَتُهُ لِدُنْيَا يُصِيبُهَا أَوْ امْرَأَةٍ يَتَزَوَّجُهَا فَهِجْرَتُهُ إِلَی مَا هَاجَرَ إِلَيْه
{Sahih Muslim (3) Hadees No.430} 

It has been narrated on the authority of Umar bin al-Khattab that the Messenger of Allahﷺ said: (The value of) an action depends on the intention behind it. A man will be rewarded only for what he intended. The emigration of one who emigrates for the sake of Allah and His Messengerﷺ is for the sake of Allah and His Messengerﷺ; and the emigration of one who emigrates for gaining a worldly advantage or for marrying a woman is for what he has emigrated.
