Imaam adh-Dhahabi 748 AH (the student of Ibn Taymeeyah) said:

فالذي يحتاج إليه الحافظ أن يكون تقيا ذكيا نحويا لغويا زكيا حييا سلفيا

“That which a scholar needs to be is:

-Taqiyan [possess fear of Allah (taqwa)]

-Dhakiyah [be intelligent]

-Nahwiyan [firm in Arabic grammar]

-Lugawiyan [firm in Arabic language]

-Zakiyan [pure in action and/or intentions]

-Hayiyan [shy]

-Salafiyyan [follow the way of the Salaf As Saleh]”
