Publisher's note for the book "Common Mistakes": In the name of Allah, the Most Gracious, the Most Merciful. All praise is due to Allah and peace be upon His chosen servants. To begin with, the monthly magazine Al-Kawsar of Markazud Dawah Al-Islamia Dhaka has been regularly published for the past 11 years. Alhamdulillah, due to His grace, this magazine has gained widespread recognition among scholars, students, and all classes of Muslims. Readers believe that Al-Kawsar plays a significant role in meeting the educational and religious needs of Bengali speakers. One recurring section that readers have favored since the beginning is "Common Mistakes." Various types of mistakes spread in society due to illiteracy, misinformation, and fragmented education. Sometimes, mistakes arise from unintentional pronunciation errors. However, it is always desirable for any mistake, regardless of its cause, to be corrected. The monthly Al-Kawsar is making that effort. Due to its popularity, the first compilation of "Common Mistakes" (up to December 2011) was published by Rahnuma Publications in November 2012. Since then, due to high demand, they have had to publish the book multiple times. We express our gratitude to them for presenting the compilation to readers for the first time and for its beautiful publication and distribution over the past few years. After the expiration of the publication period of the book in their hands, it is now being published by the publication department of Markazud Dawah Al-Islamia Dhaka. Here, the "Common Mistakes" compiled from Muharram 1426 Hijri to Muharram 1433 Hijri have been included. Before reprinting, it has been revisited by Darut Tasneef of Markazud Dawah Al-Islamia Dhaka. Nevertheless, if any errors or inconsistencies are noticed by anyone, we request you to inform us so that they can be corrected in the next edition. May Allah, the Most High, accept the efforts of Markazud Dawah, Maulana Muhammad Abdul Malek, and the monthly Al-Kawsar, grant the best rewards to all well-wishers and all involved, keep them well in this world and the Hereafter, and make this compilation of "Common Mistakes" beneficial for Muslims. Ameen. Abul Hasan Muhammad Abdullah Rais, Markazud Dawah Al-Islamia Dhaka.
