إِنَّ مِنْ أَشَدِّ أُمَّتِي لِي حُبًّا نَاسًا يَكُونُونَ بَعْدِي، يَوَدُّ أَحَدُهُمْ لَوْ رَآنِي بِأَهْلِهِ وَمَالِهِ
Translation: Some of the people of my community who love me most intensely will come after me; one of them would wish to see me even at the cost of family and wealth.
Source: مسلم
أَشَدِّ أُمَّتِي لِي حُبًّا expresses intensity of love; أَشَدّ is a comparative/superlative form. يَوَدُّ means “he deeply wishes,” and لَوْ رَآنِي expresses a longing to see the Messenger ﷺ.
Love of the Prophet ﷺ is expressed practically by learning his teachings, following them, and striving to adopt his character. The report particularly highlights the longing of later believers.
