ACTING UPON ONE’S KNOWLEDGE

In the name of Allah, the Most Gracious, the Most Merciful Zayd ibn Arqam, RadhiAllahu Anhu, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, said: اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عِلْمٍ لاَ يَنْفَعُ وَمِنْ قَلْبٍ لاَ يَخْشَعُ وَمِنْ نَفْسٍ لاَ تَشْبَعُ وَمِنْ دَعْوَةٍ لاَ يُسْتَجَابُ لَهَا O Allah, I seek refuge in you from knowledge that does not benefit, from a heart that is not reverent, from a soul that is not content, and from a supplication that is not answered .

He will go around them  as a donkey around a millstone. The people of Hell will gather around him and say: What has happened to you? Were you not enjoining good and forbidding evil? He will say: Of course, I used to enjoin good but I did not practice it myself, and I used to forbid evil but I practiced it myself .

I said: O Gabriel, who are these people? Gabriel said: Preachers from your nation who commanded people to be righteous and they forgot it themselves, yet they recited the Book. Will they not reason?
