How Did Islam Really Spread?
A 14-minute paper-collage documentary for YouTube that answers the question the way historians do: from what people left behind. Conquest is stated plainly; so is the slow, mostly voluntary conversion that followed it, the merchants, teachers, courts and farmers who carried the faith where no army went, and the exceptions where force was used.

Description
How did Islam really spread? Armies conquered in decades; conversion took centuries. The spread of Islam, told from the sources. No music: only natural sound, paper and voice. From Medina and the Islamic conquests to Indonesia, the Sahara, the Volga and Bengal: how Islam spread, told through what people left behind. Conquest and forced conversion are named plainly, and historians such as Hugh Kennedy and Richard Eaton answer: was Islam spread by the sword?

Notes for the reviewer
- Two sacred moments, each used once. Qur'an 2:256 writes itself in a Mushaf font during an 8.5 s silence (about 4:19–4:28): room tone only, no recitation. The bookend hadith (Musnad Ahmad 16957, Tamim al-Dari (ra); isnad sahih per al-Arna'ut, sahih per al-Albani) appears in an ink bloom at 13:08–13:35. Sacred text is never torn or blotted; it fades away whole.
- Please have a native Arabic reader proofread every Arabic line: 2:256 and 49:14, the Bukhari 3925 and 4302 cards, Umar ibn Abd al-Aziz's letter (ch. 4) and the bookend hadith. Some vocalisation was added by the researcher, not copied from a printed edition.
- Balance. Conquest is said plainly in the first 20 seconds and again in chapter 3, where the hostile Coptic witness's account of the killings is included. The tax incentive, Umayyad governors who discouraged conversion, and the cases where force or coercion played a part are each named and sourced. Chapter 9 gives the historians' verdict (Kennedy, Lapidus): most conversion was voluntary and slow; forced conversion was real but exceptional.
- Two narration lines differ from the approved script. They were changed to what the voice could say clearly. P49 now reads “…using informants, but he never crossed the desert.” (the take added “but”, and the script now matches). P62 now reads “You count tents.” (the original “In tents.” was heard as “Intense” in every take).
- Listen at 13:38, where the story voice hands over to the Qaf call to action. Line 1 was retaken to match the film's pitch and both lines were EQ-matched. Every band measures within 2 dB, but an AI listener still hears a slight step.
- The Qaf phone screen shows Qaf's real answer to this question, an unedited excerpt. “Searched 38 sources” counts the sources Qaf cited, not everything it read.
- sunnah.com blocked automated reading (HTTP 403) during research. The hadith numbers and gradings were checked on the hadithunlocked.com mirror, which uses the same numbering and lists the graders. Please open the sunnah.com links in the description by hand before upload.
- Known style notes. The wide maps and the tissue overlay score 2.0–2.5 out of 5 with the AI style judge. I looked at them myself and kept them. The bookend palms stay where they are, because moving them covered the village roofs.
