Sahih Muslim 44
Sahih Muslim · Book 1: The Book of Faith · The obligation to love the messenger of Allah (saws) more than one's family, son, father, and all other people; And mentions of an absolute absence of faith regarding one who does not love him with such love
It is reported on the authority of Anas b. Malik that the Messenger of Allah said:
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، حَدَّثَنَا شُعْبَةُ ، قَالَ سَمِعْتُ قَتَادَةَ ، يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يُؤْمِنُ أَحَدُكُمْ حَتَّى أَكُونَ أَحَبَّ إِلَيْهِ مِنْ وَلَدِهِ وَوَالِدِهِ وَالنَّاسِ أَجْمَعِينَ " .
None of you is a believer until I am dearer to him than his child, his father, and the whole of mankind.
