In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Shaikh Muhammad Baazmool [may Allaah preserve him] said:
The scholar possesses knowledge and precise understanding to aid him derive [sound] ruling [from the texts of the Sharee’ah]. So, when a Naazilah [i.e. an affair related to public safety or fear] occurs, he is able to quickly derive a ruling, teach the people, disseminate the ruling and explain the Sharee’ah ruling related to that [particular] Naazilah. The ability [to do this] is not acquired by merely reading books when a Naazilah occurs, without the oral skills, knowledge and prolonged experience possessed by the scholars.
