Allah (SWT) says:
“The likeness of those who were given to carry the Torah, then they did not carry it,is as the likeness of an ass that carries books. Evil is the likeness of the people who gave lies to the signs of God and God does not guide the wrong-doing people.” (Al.Jumma: 05)
Here the word “Lie” is of worth consideration. Slander can be from words or from the action. It means it can be verbal or practical. Its also a kind of slandering if Bani Israel said that Torah is not a revealed book, but the history is evident that they never betrayed in this regard. Yes, they did the practical defamation. That practical defamation which Muslim Ummah is portraying now. Instead of making Quran a guidance, a pathway and a torchlight most of Muslims have kept it in the cupboards.
Quran has narrated it as:
“Evil is the likeness of the people who gave lies to the signs of God”
If its not the betrayal of Allah’s saying than what it is??
Either we take many oaths of having Faith in Quran from our tongue , if we do not follow,adopt and implement the teachings of Quran and do not alter our individual and social ways in accordance with it than in-fact we are disobeying Quran.
