(19) باب النِّيَّةِ فِي الْيَمِينِ
It was narrated from 'Umar bin Al-Khattab that the Prophet said:
"Actions are but by intentions, and each person will have but that which he intended. Thus, he whose emigration was for the sake of Allah and His Messenger, his emigration was for the sake of Allah and His Messenger, and he whose emigration was to achieve some worldly gain or to take some woman in marriage, his emigration was for that for which he emigrated."
