Saying Allahu Akbar on coming near the Black Stone

The Prophet ﷺ performed tawaf of the House of Allah riding a camel. Whenever he came to the Black Stone, he would point towards it with something he had with him (a crooked stick) and say ” اَللّٰهُ اَكْبَرُ “.

1. Sahih al-Bukhari, no. (1613). “الشي”, (some) thing, means a stick.
