Hijazi script

Sanaa manuscript: an early Quranic manuscript in Hijazi script (8th century AD)

Hijazi script (Arabic: خَطّ ٱَلحِجَازِيّ, romanized: khaṭṭ al-ḥijāzī) is an early Arabic script that developed in the Hejaz region of the Arabian Peninsula, including cities of Mecca and Medina, and was used in some of the earliest Qur'anic manuscripts. It was often shown in a sloping style called a Ma'il script (Arabic: مائل, romanized: māʾil, lit. 'sloping').

The script is notably angular in comparison with other Arabic scripts and tends to slope to the right. The script initially contained no dots or diacritical marks to indicate vowel sounds, though some included small red dots or short strokes to indicate vowels and mark verse divisions.

The Madani Script (Hijazi Script) is used in the official signs in Medina including its museums (as shown in the picture).
