Following the allocation that had been made previously, each tribe individually gathered stones and began to build their section of the Ka‘bah. When the reconstruction was complete and it was time to insert the Hajr-e-Aswad (black stone) into its place, then a great dispute arose. Swords were unsheathed and people were prepared to fight and kill one another to acquire the honor of raising the stone to its place.

After four or five days passed in this state with no decision being made, Abu Umayyah bin Mugheerah Makhzoomi, one of the eldest members of the Quraish, suggested that the decision be made by the first person to enter the doors of the Haram the next morning. Everybody was pleased with this suggestion.

Marroozi (rahimahullah) mentions:

When Abu ‘Abdillah (Imaam Ahmed bin Hambal (rahimahullah)) would remember death, he would cry so excessively that he would be choked by tears. Imaam Ahmed (rahimahullah) would say, “At times, fear of the Hereafter prevents me from eating and drinking. When I think of death, every affair and difficulty of this world becomes easy for me to endure. The life of this world is nothing more than passing phases, wherein a person consumes one meal after the next and wears one set of clothing after the next. The life of this world only remains for a few days. I do not regard anything as virtuous (in assisting one to the Hereafter) as possessing less of the world. If I was able to, I would have not associated with people so that nobody would speak about me.”

(Siyar A’laam min Nubalaa vol. 9 pg. 459)

Hijrah to Abyssinia:

After Hazrat ‘Uthmaan (radhiyallahu ‘anhu) accepted Islam, his uncle, Hakam bin Abil ‘Aas bin Umayyah, caught him and shackled him. He said to Hazrat ‘Uthmaan (radhiyallahu ‘anhu), “Have you turned away from the religion of your forefathers, accepting a new religion? By Allah! I will never release you until you forsake this new religion that you are following!” Hazrat ‘Uthmaan (radhiyallahu ‘anhu) replied, “By Allah! I will never leave this religion nor will I part from it!” Eventually, when Hakam saw the firmness and determination with which Hazrat ‘Uthmaan (radhiyallahu ‘anhu) adhered to Islam, he relented and released him.

Hazrat ‘Uthmaan (radhiyallahu ‘anhu) had performed both migrations to Abyssinia with his respected wife, Hazrat Ruqayyah (radhiyallahu ‘anha).

(Tabaqaat ibn Sa’d 3/40)

The next morning, Waleed was safe and sound. He thus took a shovel and proceeded to the Haram. People understood that Allah Ta‘ala approved of their action (of reconstructing the Ka‘bah) and thus everybody’s courage increased. Hence, they all gathered and worked together, with their hearts and souls, to accomplish this task. They continued digging until the original foundation laid by Hazrat Ebrahim (‘alaihis salaam) became visible. When a man from the Quraish tribe attempted to dig the foundation of Hazrat Ebrahim (‘alaihis salaam), a loud explosion was heard in the city of Makkah Mukarramah, due to which they immediately discontinued digging further. They then commenced building the Ka‘bah on the same original foundation.
