وَأَقِمِ الصَّلَاةَ طَرَفَيِ النَّهَارِ وَزُلَفًا مِّنَ اللَّيْلِ ۚ إِنَّ الْحَسَنَاتِ يُذْهِبْنَ السَّيِّئَاتِ ...

The initial response to a call for the Truth is that it is ignored. Thereafter opposition starts and then it soon goes beyond all limits. This is a very critical situation for the call-givers. At that time the believers begin to consider different ways of thinking. One way is to become irritated and to imagine that, with the help of force, they should clash with those on whom theoretical reasoning had proved ineffective. The other way is to amend their message suitably in order to make it acceptable to the addressees, by omitting those portions which displease them. The first way amounts to going to extremes, while the second means compromising with falsehood, and both of these are equally wrong in the eyes of God; especially the second approach (i.e. amendment of the message in order to make it acceptable) which amounts to a sin, because that which is most desired by Almighty God is the unequivocal declaration of Truth, and in the case of compromises, there cannot be any such declaration. Whenever obstacles arise in the path of giving the call to the Truth, the call-giver should turn towards God as much as possible, because He, being Omnipotent, is the sole and certain means of solving all problems.
