40 Hadith Nawawi 1

It is narrated on the authority of Amirul Mu'minin, Abu Hafs 'Umar bin al-Khattab (may Allah be pleased with him), who said:

I heard the Messenger of Allah, ﷺ, say: "Actions are (judged) by motives (niyyah), so each man will have what he intended. Thus, he whose migration (hijrah) was to Allah and His Messenger, his migration is to Allah and His Messenger; but he whose migration was for some worldly thing he might gain, or for a wife he might marry, his migration is to that for which he migrated."

[Al-Bukhari & Muslim]

عَنْ أَمِيرِ الْمُؤْمِنِينَ أَبِي حَفْصٍ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ: " إنَّمَا الْأَعْمَالُ بِالنِّيَّاتِ، وَإِنَّمَا لِكُلِّ امْرِئٍ مَا نَوَى، فَمَنْ كَانَتْ هِجْرَتُهُ إلَى اللَّهِ وَرَسُولِهِ فَهِجْرَتُهُ إلَى اللَّهِ وَرَسُولِهِ، وَمَنْ كَانَتْ هِجْرَتُهُ لِدُنْيَا يُصِيبُهَا أَوْ امْرَأَةٍ يَنْكِحُهَا فَهِجْرَتُهُ إلَى مَا هَاجَرَ إلَيْهِ".
رَوَاهُ إِمَامَا الْمُحَدِّثِينَ أَبُو عَبْدِ اللهِ مُحَمَّدُ بنُ إِسْمَاعِيل بن إِبْرَاهِيم بن الْمُغِيرَة بن بَرْدِزبَه الْبُخَارِيُّ الْجُعْفِيُّ [رقم:1]، وَأَبُو الْحُسَيْنِ مُسْلِمٌ بنُ الْحَجَّاج بن مُسْلِم الْقُشَيْرِيُّ النَّيْسَابُورِيُّ [رقم:1907] رَضِيَ اللهُ عَنْهُمَا فِي "صَحِيحَيْهِمَا" اللذَينِ هُمَا أَصَحُّ الْكُتُبِ الْمُصَنَّفَةِ.
