① Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) said:
"Convey to the people what they know; do you wish that Allah and His Messenger ﷺ be denied by revealing unknown matters?"
Reference: (Bukhari, Knowledge: 1/272, Chapter: Those Who Are Given Knowledge Over Others)
① It is narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah ﷺ said:
ما من داع يدعو إلىٰ ضلالة إلا كان عليه من الإثم مثل آثام من تبعه لا ينقص ذٰلك من أوزارهم شيئا
"Whoever invites to misguidance will bear the sin of those who follow him in it, and this does not lessen their burden or sins in any way."
Reference: (Muslim, Book of Knowledge, Hadith: 2674/16. Muwatta: 1/218, Hadith: 41)
① Sayyiduna Abdullah bin Umar رضي الله عنهما narrates, the Messenger of Allah صلی اللہ علیہ وسلم said:
إن الله لا يقبض العلم انتراعا ينتزعه من الناس، ولٰكن يقبض العلم بقبض العلماء حتىٰ إذا لم يبق عالما اتخذ الناس رؤساء جهالا، فسئلوا فأفتوا بغير علم فضلوا وأضلوا
"Allah will not take away knowledge by removing it from the hearts of the people, but He will take away knowledge by causing the death of the scholars. Until when no scholar remains, people will appoint the ignorant as their leaders, and when asked about matters, they will issue rulings without knowledge. Thus, they will themselves be misguided and will misguide others."
