First to have electricity

In 1909, it became the first place in the Arabian Peninsula to be provided with electrical lights.

When the Ottomans introduced electricity to the Arabian Peninsula, the first place to be lit up was the mosque of the Prophet ṣallallāhu 'alayhi wa sallam (peace and blessings of Allāh be upon him). By some accounts, it would be a few more years before the Sultan himself had full electricity in his own palace in Istanbul.
