HOW TO KNOW IF A HADITH IS SAHIH ACCORDING TO AHLUS-SUNNAH

Al-Imam As-Suyutiyy said in his alfiyyah (Page 8):

«وَخُذْهُ حَيْثُ حَافِظٌ عَلَيْهِ ‌نَصْ … وَمِنْ مُصَنَّفٍ بِجَمْعِهِ يُخَصْ»

which means: if you find a Hafidh explicit said so (“this hadith is sahih“) then take it from him, or a hafidh authored a book specific for it (in which he says “all the hadith in it are sahih“)
