And all the other Mushaf were burnt by the Caliph Uthman with the consensus of the companions. This written version, termed as Uthman’s script, was kept by the Caliph Uthman with himself in Madina. When Zaid (r.a) has done his job, the Mushaf with Hafsa bin umar was returned to her.
For this purpose Uthman borrowed the first written version of the Holy Quran from Hafsa to make a standard copy. In the 25 A.H.(646 A.G.) the third caliph Uthman (r.a) directed Zaid bin Thabit along with three other Companions Abdullah bin Zubair, Saad bin Alas and Abdur Rahman bin Harith bin hashim (r.a) to prepare a single standard, authentic and reliable copy from the first written version of the Holy Quran possessed by Hafsa (r.a). It was worth nothing that some other versions as Mushaf Ubai Ibn Kab and Mushaf Ibn Masud, were also exist at that time. This first complied text known as Al Jamul Awwal was kept with Abu Bakr (r.a), then with the second Caliph Umar and at at last with Hafsa bin Umar (r.a) mother of believers. Zaid bin Thabit (r.a) put together all the parts of the Holy Quran in the form of a written complied text as he was instructed by the first caliph Abu Bakr (r.a). When the prophet died in 11 A.H.(632 A.G.), all parts of the Holy Quran was preserved, both in writing and in the memory of the companions, with the same order of the Ayat and Suwar in the holy Quran as the Prophet Muhammad exactly received it and then dictated it to others. The companions not only learnt the Quran by heart during the prophet’s life, but they also wrote it down on different kinds of materials such as bones, stones, leaves, skin, etc.
Most of the companions learnt the Holy Quran by heart as it was revealed to the prophet Muhammad (Sallahu alahi wassalam) through the arch angel Jibreel. The Holy Quran was transmitted to the prophet Muhammad in seven Ahruf to accommodate the different Arab tribes as compared to their local dialectal phenomenon.
