Love of Ahlull Bayt (the Prophet’s family and progeny) is an integral part of all Muslims’ faith. Some misguided people think that Sunni do not love Ahlul Bayt, due to misguided sects such as Nasibis and Wahhabis and due to their false preaching and misguidance, some people from Sunni creed and sects think that loving Ahlul Bayt is becoming Shia!
Both ways are wrong, Ahlu Sunna always loved and followed the way of ahlul bayt.
Due to the corruption that is happening in the Muslim world, people have been misguided so much after the Ottoman Caliphate was destroyed!
All Imams of Tasawwuf (Tariqah) are from Ahlul Bayt, it is from the Spiritual Knowledge and Purification of Heart revealed and transmitted from time to time.
So when you start Malice against ahlul bayt and Sahaba, that time you are playing a disrespectful game with the trust of Allah’s Messenger (alaihiswalathu wa salam)!, Beware, be careful oh Jahil Sunnis and Jahil Shias!
Daylmi narrates from Sayyiduna Abu Sa’eed that the Prophet (s.a.w) said :

أهل بيتي والأنصار كٌرشي وعيبتي وصحابي وموضع مسرتي وأمانتي فاقبلوا من محسنهم وتجاوزوا عن مسيئهم
‘My Ahl ul Bait and the Ansaar are my wealth, my body, my household and my family, the locus of my happiness and my trust. So accept the good deeds of their good and overlook the mistakes of any of them (not from the Hudood of Allah).’ [Daylami in Al-Firdaws, Vol. 1, Page 407, Hadith 1645]
So, Imam Shafi’ (R.A) s Testimony on Ahlul Bayt is very relevant at this time. I am sure those who are sick in their heart and those who want to cause fitnah will reject these testimonies:
In one of the hajj rituals when pilgrims were at Mina and when some enemies of the Ahlul-Bayt (as) were in attendance, Shafi’i called the love of Ahlul-Bayt an entitlement of the family of the Prophet and addressed the pilgrims as such:

یا راکِباً قِف بالمُحَصَّبِ مِن منیًوَاهتِف بِقاعِدِ خَیفِها وَالنَّاهِضِسَحَراً إذا فاضَ الحَجیجُ إلی مِنیًفَیضاً کَمُلتَطِمِ الفُراتِ الفائِضِإن کانَ رَفضاً حُبُّ آلِ مُحمَّدٍفَلیَشهَدِ الثَّقَلانِ أنّی رَافضِی

Translation:“O’ Pilgrims! On your way to the House of Allah, pause shortly in the sands of Muzdalifah. At dawn, when the caravans of pilgrims move toward Mina, like a roaring river, call upon them and say: “If the love of the Prophet’s family means “rafdh”, then let mankind know, that surely I am a “Rafedhi.”
One of the points raised in Shafi’i’s poems is love of Ahlul-Bayt, the family of the Prophet (peace be upon him and his family) which he deems obligatory. Shafi’i maintains that if a person does not declare salawaat for him and his family, his prayer is incomplete and will not be accepted:
یا آلَ بَیتِ رَسولِ الله حُبُّکُمُفَرضٌ مِنَ الله فی القُرآنِ أنزَلَهُکَفاکُم مِن عظیمِ القَدرِ أنّکُممَن لَم یُصلِّ عَلَیکُم لَا صَلَاةَ لَهُ

Translation:“O Ahle Bait of the Prophet of Allah! Love for you has been made obligatory for us by Allah, as revealed in the Holy Qur’an (referring to the above verse). It is sufficient for your dignity that if one does not send salutations to you in the ritual prayers, his prayers will not be accepted.”
قَالُوا: تَرَفَّضتَ قُلتُ: کَلَّامَا الَّرفضُ دینی وَ لا إعتِقادیلکِن تَوَلَّیتُ غَیرَ شَکٍّخَیرَ إمَامٍ وَ خَیرَ هَادیإن کَانَ حُبُّ الوَلِیِّ رَفضاًفإنَّنی أرفَضُ العِبادَ

Translation:They say: You are a Rafedhi and heretic, I say: Never did I become a Rafedhi, apostasy is not my religion. But needless to say that in my heart, there is much love (and respect) for the greatest leader (Imam Ali (As). If loving Wali of Allah (the friend of God?) is Rafdh, then I’m Rafedhi of 1st rank!In other poems, he makes clear and tangible reference to the intercession of the Ahlul-Bayt (as) of the Holy Prophet (pbuh) hoping to be interceded with God by them on the Day of Resurrection, the day of reckoning:
لَئِن کانَ ذَنبِی حُبُّ آلِ محمَّدٍفذلِکَ ذَنبٌ لَستُ عَنهُ أتوبُهُمُ شُفَعائی یومَ حَشری و مَوقِفی إذاکثرتنی یوم ذاک ذنوب
If loving the household of Prophet (pbuh) is a sin, then I will never repent on this sin!Of course, on the Day of Judgment, they (Ahl-e-Bait) will be my intercessors on the Day when I shall be resurrected. That is when my sins are too many on that day.
بَرِئتُ إلَی المُهیمِنِ مِن أُناسٍیَرَونَ الرَّفضَ حُبَّ الفاطِمیّهإذا ذکروا عَلیّا أو بَنیهأفاضوا بالرّوایات الویّهعَلی آل الرّسُول صلاة رَبیوَ لَعنتُه لتلکَ الجَاهلیّه
I disassociate myself from those (people) who believe that remembering the sons of Fatima (AS) is Rafdh. If anyone talks about Ali (as) and Fatima (as) and their sons, they (enemies of Ahl-e-Bayt) mend this way, they think that it is foolishness (to remember Ali and Fatima). Supplications (Duroods and Salams) of my Allah be upon Prophet (pbuh). And the curse of Allah be upon this ignorance and infidelity (hating Ahul-Bayt).
و سائلی عن حُب أهل البیت هل؟أُقرّ إعلاناً به أم أجحدُهَیهاتَ ممزوجٌ بلحمی و دَمیحُبُّهم و هو الهُدی و الرشدُیا أهل بیتِ المصطفی یا عدتیوَ مَن علی حبّهُم أعتَمدُأنتم إلی اللهِ غَداً وَسیلَتیو کیف أخشی؟ و بکم اعتضدُولیّکم فی الخُلدِ حَیّ خَالدٌو الضدُ فی نارٍ لَظیً مُخلّدُ

Translation:“O those who ask me about my love of Ahlul-Bayt (as); should I confess openly that I love them or should I deny that? Never shall I deny their love because their love and affinity is blended in my flesh and blood. Their love is a means of my guidance and growth. O family of Muhammad, O those whom I turn to, O those whose love is my reliance, you are my intercessors on the Day of Judgment. Why should I be afraid when I trust you and have confidence in you? He who loves you will reside eternally in Paradise and your enemies will be for ever in Hell fire”
وَ لَمَّا رَأیتُ النَّاسَ قَد ذَهَبَت بِهِممَذَاهِبُهُم فِی أبحُرِ الغَیِّ وَ الجَهلِرَکِبتُ عَلَی اسمِ الله فِی سُفُنِ النَّجَاوَ هُم آل بَیتِ المُصطفَی خَاتَمِ الرُّسُلِوَ أمسَکتُ حَبلَ اللهِ وَ هُوَ وَلاءوهُمکَما قَد أُمِرنَا بالتَمسُّکِ بالحَبلِ
When I saw different religions and jurisprudential schools steering towards ignorance and misguidance, I embarked in the name of God on the ark of salvation i.e. the family of the Seal of Prophets and got hold of the divine covenant which is the very love of them. Indeed, God has commanded us to hold fast to the divine covenant.
