Love of the Prophet’s Family and the Companion is a practice of the Ahle Sunnah
The Holy Prophet (Sallallahu alaihi wa sallam) has declared the Prophet’s Family as the ark of deliverance and safety and the Companions as the stars of guidance.
Translation: My Companion are like the stars of guidance. Whomever you follow, you will be guided. (Mishkaatul Masabeeh, Pg No. 54; Zujajatul Masabeeh, Vol. 5, Pg No. 334)
Hadhrat Mulla Ali Qari writes in Mirqaat Ul Mafateeh on the authority of Imam Fakhruddin Radhi (May Allah shower His mercy on both of them):
Translation: By the grace and benevolence of Allah Ta’ala, we, the Ahle Sunnah are in the ship of the love of the Prophet’s Family and are also being guided by the stars of guidance i.e. the Companion of the Holy Prophet (Sallallahu alaihi wa sallam). We hope that Allah Most High will save us from horrors of the Day of Judgment and from the tortures of hell and will grant us high stations in heaven, which is eternal.
