باب وُجُوبِ مَحَبَّةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَكْثَرَ مِنَ الأَهْلِ وَالْوَلَدِ وَالْوَالِدِ وَالنَّاسِ أَجْمَعِينَ وَإِطْلاَقِ عَدَمِ الإِيمَانِ عَلَى مَنْ لَمْ يُحِبَّهُ هَذِهِ الْمَحَبَّةَ
None of you is a believer until I am dearer to him than his child, his father, and the whole of mankind.
