Narrated 'Abdullah bin Hisham:

We were with the Prophet and he was holding the hand of 'Umar bin Al-Khattab. 'Umar said to Him, "O Allah's Apostle! You are dearer to me than everything except my own self." The Prophet ﷺ said, "No, by Him in Whose Hand my soul is, (you will not have complete faith) till I am dearer to you than your own self." Then 'Umar said to him, "However, now, by Allah, you are dearer to me than my own self." The Prophet ﷺ said, "Now, O 'Umar, (now you are a believer)."

حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنِي ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي حَيْوَةُ، قَالَ حَدَّثَنِي أَبُو عَقِيلٍ، زُهْرَةُ بْنُ مَعْبَدٍ أَنَّهُ سَمِعَ جَدَّهُ عَبْدَ اللَّهِ بْنَ هِشَامٍ، قَالَ كُنَّا مَعَ النَّبِيِّ ﷺ وَهْوَ آخِذٌ بِيَدِ عُمَرَ بْنِ الْخَطَّابِ فَقَالَ لَهُ عُمَرُ يَا رَسُولَ اللَّهِ لأَنْتَ أَحَبُّ إِلَىَّ مِنْ كُلِّ شَىْءٍ إِلاَّ مِنْ نَفْسِي. فَقَالَ النَّبِيُّ ﷺ " لاَ وَالَّذِي نَفْسِي بِيَدِهِ حَتَّى أَكُونَ أَحَبَّ إِلَيْكَ مِنْ نَفْسِكَ ". فَقَالَ لَهُ عُمَرُ فَإِنَّهُ الآنَ وَاللَّهِ لأَنْتَ أَحَبُّ إِلَىَّ مِنْ نَفْسِي. فَقَالَ النَّبِيُّ ﷺ " الآنَ يَا عُمَرُ ".
