ابن حجر العسقلاني
Ibn Shihab al-Zuhri is regarded as one of the greatest Sunni authorities on "Hadith". The leading critics of Hadith such as Ibn al-Madini, Ibn Hibban, Abu Hatim, Al-Dhahabi and Ibn Hajar al-Asqalani are all agreed upon his indisputable authority. He received "ahadith" from many "Sahaba" (Companions) and numerous scholars among the first and second generations after the Companions narrated from him.
