To love the Holy Prophet s.a. is a part of faith

عَنْ أَنَسٍ، قَالَ قَالَ النَّبِیُّ صَلَّی اللہُ عَلَیْہِ وَسَلَّمَ لَا یُوْمِنُ أَحَدُکُمْ حَتَّی أَکُوْنَ أَحَبَّ اِلَیْہِ مِنْ وَالِدِہِ وَوَلَدِہِ وَالنَّاسِ أَجْمَعِیْنَ

Hazrat Anas^ra narrates that the Holy Prophet^sa said:

“None of you will have faith till he loves me more than his father, his children and all mankind.”

(Sahih al-Bukhari, Kitab al-Iman, Hadith 15)
