One of the reasons why the da’wat nowadays is not effective is the abundance of haraam we are involved in. It won’t be an exaggeration if it is said that 70 to 80 percent of people engage in indecent works (including porn etc.). It brings you to a level when you begin to consider the wrong as right. One begins to feel nothing about it; there can be free mixing at work, at weddings, etc. Then at the wedding which is mixed, we will want to invite some Moulanas. So we will make a separate area for them and even say to them that we considered you and made this separate arrangement. It is as if we are doing that part for them, but then there is no consideration for Allah Ta‘ala and the sharee‘ah in the rest of the nikaah. Look at the manners of finance, interest, gambling and insurance. People get involved in it to such an extent that they go to the level of denial and begin to say that how can life carry on without these things. On account of the abundance of haraam the heart becomes disfigured and the mind and understanding are distorted. The whole family can be sitting in front of the TV and watching someone else’s wife and husband. This is wholesale zina.
