The Al-Durar Al-Sunniyyah Wal-Kalam Al-Tayyib developer presents the free Islamic app, "الشرح الممتع لابن عثيمين صوت" for Android users. This educational app consists of audio lessons that explain the book "زاد المستقنع لابن عثيمين" in a modern and authentic way. The book is considered one of the most important texts in Islamic jurisprudence and is served by investigation, annotation, and explanation among Muslims.

The author, Sheikh Muhammad bin Saleh Al-Uthaymeen, used to teach the book to his students and encourage them to memorize it. Later, Sheikh Ibn Al-Uthaymeen began teaching it to people in Al-Jami' Al-Kabir in Unaizah and explaining it to them scientifically. These sessions were recorded and circulated. Then, some of the sheikh's students followed this audio material, classified and arranged it, and extracted its hadiths to produce the book "الشرح الممتع على زاد المستقنع."
