Consequently...
Consequently, it does not need any detailed explanation to show that Umayyah and Hashim, Harb and 'Abd al-Muttalib and Abu Sufyan and Abu Talib were not match of each other from any angle. This is not denied by any historian nor by any biographer.
In fact, after this reply even Mu'awiyah did not dare refute it, because the fact could be concealed that after 'Abd Manaf it was Hashim alone who possessed conspicuous prestige among the Quraysh, and the most important positions with relation to the Ka'bah namely siqayah (i.e., the superintendence of the water-supply, especially with a veiw to the needs of pilgrims) and rifadah (provisioning of pilgrims) was assigned to him.
As such, at the time of hajj, caravan after caravan used to come and stay with him and he was such a generous host to them that those who partook of his generosity and benevolence would praise him for long thereafter. The worthy son of this very large-hearted and courageous father was 'Abd al-Muttalib whose name was Shaybah and surname was Sayyidu'l-Batha' (the Chief of the Valley of Mecca).
He was the successor to the distinction of Abraham's line and owner of the greatness and chiefdom of Quraysh. The high courage and far-sightedness showed by him before Abraham is a shining star of the family of 'Abd Manaf.'Abd Manaf was a pearl and 'Abd al-Muttalib was the lustre of the pearl. 'Abd al-Muttalib's son was Ahu Talib whose lap served as the cradle for 'Abdullah's orphan child and the training place of the Prophet.
He brought up the Prophet in his care, and shielded him against his enemies. To compare Abu Sufyan, Harb and Umayyah with them or to regard them as their matches is the same as to close one's eyes to the lustre of light and to regard it as darkness.
After recounting this geneological difference the next point of distinction that Amir al-mu'minin has described is that he himself is a muhajir (immigrant from Mecca) while Mu'awiyah is a taliq (i.e., one of those whom the Prophet had spared on the day of fall of Mecca).
Therefore, when the Prophet entered Mecca victorious he enquired from the Quraysh how they thought he would deal with them, and all said that being a generous son of a generous father they expected only good from him, whereupon the Prophet said, "Go away, you have all been spared." That is, "you did deserve to be detained as slaves but as a mark of obligation you have been left free." These spared ones included Mu'awiyah and Abu Sufyan also.
