requested of me now". (Al-Bukhari, Sahih, Jam'i al-Qur'an, hadith no. 4986; see also Ibn Abu Dawud, al-Masahif, pp. 6-9) His reaction to the task and its difficulties are further explained: "...By Allah, if he (Abu Bakr) had ordered me to shift one of the mountains it would not have been harder for me than what he had ordered me concerning the collection of the Quran... So I started locating the Quranic material and collecting it from parchments, scapula, leafstalks of date palms and from the memories of men. [Bukhari ] Al-Zarakhsi comments, What Zaid means in fact is that he sought out verses from scattered sources, to collate them against the recollections of the huffaz. In this way everyone participated in the collection process. No one possessing any portion of it was left out, and so no one had reason for expressing concern about the verses collected, nor could anyone complain that the text had been gathered from only a select few.

Ibn Hajar al-Asqalani draws special attention to Zayd's statement, "I found two verses of Sura al-Bara'a with Abu Khuzaima al-Ansari," as demonstrating that Zayd's own writings and memorization were not deemed sufficient. Everything required verification. Ibn Hajar further comments: Abu Bakr had not authorized him to record except what was already available [on parchment]. That is why Zaid refrained from including the last two verses of Sura Bara'a until he came upon it in written form, even though he and his fellow Companions could recall it perfectly well from memory. The task required Zayd ibn Thabit to collect written copies of the Quran, with each verse having been validated with the oral testimony of at least two companions. The Quran was collected under the auspices of committee of four senior ranking Companions headed by Zayd ibn Thabit. This compilation was kept by the Caliph Abu Bakr, after his death by his successor, Caliph Umar, who on his deathbed gave them to Hafsa bint Umar, his daughter and one of Muhammad's widows.
