An excellent lecture in English in which Sh. Abdurrahim Green confirms that we all sin but how many of us unintentionally commit major sins? In this lecture, Sh. Abdurrahim Green informs us of some of the major sins that we do not know such as speaking about Allah and His religion without knowledge, arrogance, pride, supporting the disbelievers against the believers, magic, fortune telling, showing off, and heresies.
