28-Kufuri Bakko is an Islamic learnable best book written by Muhammad Ilyas Attar Qadri Razavi. We are Muslims, and we should think very carefully about every word, which is not shared by God with our words. This book is written about twenty-eight sentences that go out of our mouth in the wrong order. And as a result, we have many great sins. So, we have to read this book and avoid those great sins.
