Questioner: If I have turned to [wanting to practise] the religion and have no knowledge and an Islamic group asks me to go out with them for da’wah and some brothers at the mosque warn me stating that this jamaa’ah is called the Tableeghi Jamaa’ah and it is not right for me to go out with them because they have corrupt beliefs, what should I do?
Al-Albaani: Seek knowledge, what’s the problem, seek knowledge.
Questioner: Ya’ni, is it permissible for me to go out with them now?
Al-Albaani: Their going out is not from the Sunnah. Their sitting in the mosques and seeking knowledge and studying the Book of Allaah as occurs in the authentic hadith, that is what is legislated. As for their going out like this in groups, and most of them only know very little about Islaam, this is something which they have opposed the Muslims from the time of the Prophet to this day in.
Before this time, thirty or forty years ago, there was no Jamaa’ah that would go out like this with tens or hundreds of people without even a single scholar found amongst them.
The people of knowledge are widespread in Jordan and Syria and we advise these people to sit in the gatherings of knowledge and to learn, and this is what we advise you with too. We say to you: attend the gatherings of knowledge, the sittings of knowledge and learn.
As for this going out [khuruj]–it has no basis in the Sunnah.
