In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Imaam Abdul Bin Baaz [rahimahullaah] said: The student of knowledge is very eager not to hide anything he knows. He is eager to clarify the truth and refute the opponents of the Religion of Islaam. He is neither lackadaisical nor does he seek to escape.
When the opponents of Islaam appear with that which obscures and defames Islaam, he brings forth refutation against them by writing, by word of mouth and other than that.
He does not seek to escape, rather he comes forward at the appropriate time to aid the truth and refutes the opponents of Islaam by writing and other than it- by means of the radio, the newspapers or TV, or through any means he can.
He does not hide what he has of knowledge, rather he writes, gives khutbah and refutes the people of innovation and other than them from the opponents of Islaam based on what Allaah has bestowed upon him of strength – in accordance with his knowledge and that which Allaah has made easy for him. Allaah [The Most High] said:
إِنَّ ٱلَّذِينَ يَكۡتُمُونَ مَآ أَنزَلۡنَا مِنَ ٱلۡبَيِّنَـٰتِ وَٱلۡهُدَىٰ مِنۢ بَعۡدِ مَا بَيَّنَّـٰهُ لِلنَّاسِ فِى ٱلۡكِتَـٰبِۙ أُوْلَـٰٓٮِٕكَ يَلۡعَنُہُمُ ٱللَّهُ وَيَلۡعَنُہُمُ ٱللَّـٰعِنُونَ
إِلَّا ٱلَّذِينَ تَابُواْ وَأَصۡلَحُواْ وَبَيَّنُواْ فَأُوْلَـٰٓٮِٕكَ أَتُوبُ عَلَيۡہِمۡۚ وَأَنَا ٱلتَّوَّابُ ٱلرَّحِيمُ
Verily, those who conceal the clear proofs, evidences and the guidance, which We have sent down, after We have made it clear for the people in the Book, they are the ones cursed by Allaah and cursed by the cursers. Except those who repent and do righteous deeds, and openly declare (the truth which they concealed). These, I will accept their repentance. And I am the One Who accepts repentance, the Most Merciful” [2:159-160]
