The Prophet (ﷺ) clarified that a person does not attain the complete obligatory faith until his love is in accordance with what the Messenger (ﷺ) brought of commands, prohibitions, and other matters—so that he loves what he commanded and dislikes what he forbade.
Lessons
The Hadīth represents a rule of yielding to the Shariah and submitting to it.
It warns us not to refer to our minds or habits for judgment and give them precedence over what the Messenger (ﷺ) came with. Imān (faith) is negated from those who act like that.
It is obligatory to refer for judgment to the Shariah in all matters, based on his statement: "with what I have come with."
Imān increases by good deeds and decreases by sins.
Explanation in Arabic
بين النبي صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ أن الإنسان لا يكونا مؤمنًا كامل الإيمان الواجب حتى تكون محبته تابعة لما جاء به الرسول صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ من الأوامر والنواهي وغيرها، فيحب ما أمر به، ويكْرَهُ ما نَهَى عنه.
الحديث قاعدة في التسليم للشرع والانقياد له.
تحذير الإنسان من أن من يحكم العقل أو العادة ويقدمه على ما جاء به الرسول صلى الله عليه وسلم، ففاعل ذلك قد نُفي الإيمان عنه.
وجوب تحكيم الشريعة في كل شيء، لقوله: «لِمَا جِئتُ به».
