When Muhammad ﷺ was thirty-five years old, the Quraysh undertook the rebuilding of the Ka'bah after it was damaged by floods. A dispute arose over who would have the honor of placing the Black Stone (al-Hajar al-Aswad) back in its corner. The tribes were on the verge of conflict when they agreed to let the next person to enter the Ka'bah precinct decide. Muhammad ﷺ entered, and they exclaimed 'Al-Amin!' (The Trustworthy One). He placed the Black Stone on a cloth and had representatives of each tribe hold a corner and lift it together, then he placed the stone with his own hands.
