Qusaiyy had 4 sons: ‘Abdud-Dār, ‘Abdul-‘Uzzā, ‘Abdu Manāf and ‘Abdu Qusaiyy. Since ‘Abdud-Dār was the eldest, upon his deathbed Qusaiyy entrusted the entirety of his responsibilities, namely, the three offices in the custodianship of the Ka‘bah, Dārun-Nadwah and Liwā’ to him. However, ‘Abdud-Dār was not a man of his father’s ability and intelligence. Therefore, ‘Abdu Manāf who was a very intelligent and able man acquired the common rule of the Quraish. ‘Abdu Manāf had 4 sons: ‘Abdu Shams, Muṭṭalib, Hāshim and Nawfal, all four of them inherited the abilities of their father. As such, succeeding the death of ‘Abdu Manāf, they collectively sought to take away the custodianship of the Ka‘bah from the children of ‘Abdud-Dār, upon which both parties fell into mutual dissention. Some of the tribes of the Quraish took one side while the others took another. All were at the brink of war, but ultimately a decision was made in peace and harmony. The two offices of Rifādah and Siqāyah were given to the ‘Abdu Manāf, and the remaining three, in other words, the administration of Dārun-Nadwah, Liwā’ and Ḥijābah, remained with the ‘Abdud-Dār. After mutual consultation, the ‘Abdu Manāf made Hāshim the custodian of the tasks of Siqāyah and Rifādah.1
