When the Messenger of Allah S reached thirty-five years of age, the Quraysh wanted to demolish the Ka’bah to rebuild it again, as its walls had cracked and it was just about to fall down. Moreover, it did not have a roof so a group of thieves stole the treasures kept inside it. Therefore, the Quraysh had to rebuild it; they were eager to keep it in good shape. They agreed that they would use only pure money, so money gained from usury or from repressing people was not used in rebuilding it. But they feared that demolishing the Ka’bah would earn Allah’s anger.
