Rasulullah صلى الله عليه وسلم  had said :

“BEWARE OF THE FIRASAT (INSIGHT) OF THE MU'MIN, FOR VERILY, HE SEES WITH THE NOOR OF ALLAH.”

To illustrate this perception and insight of the heart, I will relate a story of a Jew who, having been informed of this quality of ‘firasat’, to be found in a Mu'min, decided to test
the veracity and truth of the statement of Rasulullah صلى الله عليه وسلم .

He donned the garb of a Muslim and approached Hazrat Junaid Baghdadi (Rahmatullah ‘alaih). After Salaam and some social niceties,he enquired : “What is this ‘firasat’ of a Mu'min?”

Hazrat Junaid Baghdadi (Rahmatullah ‘alaih) replied : “The firasat of a Mu'min is this: that you are a Jew and not a Muslim.” This manifestation of truth became a means of Hidayat (guidance) and the Jew embraced Islam.

Of course, the pre-condition to such ‘firasat’ is that the person has to be a true and perfect Mu'min (Believer); the ingredients of which are Taqwa and Righteous Deeds.
