We as Ahlus sunnah accept the hadith: Man Kunto Mawlahu fa `Aliyyun mawlahu i.e. For whosoever I am Mawla then Ali is his Mawla [Sunnan Tirimdhi, Hadith # 3713, where Imam Tirimdhi called it "Hasan Sahih" and Albani proved it to be Sahih too]
Let's see the authenticity of this beautiful hadith in words of Nasir ud-din Albani:
Translation: (The Prophet - Peace be upon him said): For whosoever I am Mawla then Ali is his Mawla, O Allah befriend those who befriend Ali and be enemy of those who are enemy to Ali (Albani Says): This hadith has come from Zayd ibn Arqam, Sad bin Abi Waqqas, Buraida bin Husayb, Ali bin Abi Talib, Abu Ayyub al Ansari, Bara bin Azib, Abdullah Ibn Abbas, Anas bin Malik, Abu Saeed and Abu Hurraira (Ridhwan Allahu Ajmain), The Hadith of Zayd bin Arqam comes with 5 (different) ways!... [Albani in: Silsilat ul ahadith as-Sahiha, Volume No. 4, Page No. 330, Hadith Number 1750]
Albani then says:
