Suyuti [Itqan 1, uk. 124.] anataja zaidi ya watu ishirini maarufu waliohifadhi wahyi, miongoni mwao walikuwa Abu Bakr, 'Umar, 'Uthman, 'Ali, Ibn Mas'ud, Abu Huraira, 'Abdullah bin 'Abbas, 'Abdullah bin 'Amr bin al-'As, 'A'isha, Hafsa, na Umm Salama.
Suyuti [Itqan 1, p. 124.] mentions more than twenty well-known persons who memorized the revelation, among them were Abu Bakr, 'Umar, 'Uthman, 'Ali, Ibn Mas'ud, Abu Huraira, 'Abdullah bin 'Abbas, 'Abdullah bin 'Amr bin al-'As, 'A'isha, Hafsa, and Umm Salama.
Miongoni mwa haya, Mtume ﷺ mwenyewe alisisitiza hasa yafuatayo:
From among these, the Prophet himself recommended especially the following:
"Imesimuliwa kutoka kwa Masruq: 'Abdullah bin 'Amr alimtaja 'Abdullah bin Mas'ud, akasema: Nitampenda mtu huyo daima, kwani nilimsikia Nabii ﷺ akisema: Jifunzeni Qur'an kutoka kwa wanne: 'Abdullah bin Mas'ud, Salim, Muadh na Ubay bin Ka'b'. [Bukhari, VI, Na. 521.] Hadith nyingine inatujulisha kuhusu Masahaba wale ambao walikuwa wameihifadhi Qur'an yote na kuipitia pamoja na Nabii ﷺ kabla ya kufariki kwake:"
'Narrated Masruq: 'Abdullah bin 'Amr mentioned 'Abdullah bin Mas'ud and said: I shall ever love that man for I heard the Prophet saying: Take (learn) the Qur'an from four: 'Abdullah bin Mas'ud, Salim, Muiadh and Ubay bin Ka'b'. [Bukhari, VI, No. 521.] Another hadith informs us about those Companions who had memorized the Qur'an in its entirety and gone over it with the Prophet before his death:
'Imesimuliwa kutoka kwa Qatada: Nilimuuliza Anas bin Malik: Ni nani aliyekusanya Qur'an wakati wa Nabii ﷺ? Alijibu, "Wanne, wote wao walikuwa katika Answar: Ubay bin Ka'b, Mu'adh bin Jabal, Zaid bin Thabit na Aba Zaid." [Bukhari, VI, Na. 525.] Ukweli kwamba baadhi ya ripoti za mwanzo kabisa za kihistoria zinataja kwa namna ya pekee, katika masimulizi ya vita vilivyopiganwa, Waislamu waliouawa waliokuwa wakiijua (sehemu ya) Qur'an kwa moyo, unaonyesha wazi kwamba kuhifadhi ufunuo kwa kukariri kulichukuliwa kuwa jambo muhimu na lilifanywa sana tangu zama za mwanzo. [See below, on collection of the Qur'an in Abu Bakr's time.]
'Narrated Qatada: I asked Anas bin Malik: Who collected the Qur'an at the time of the Prophet? He replied, Four, all of whom were from the Ansar: Ubay bin Ka'b, Mu'adh bin Jabal, Zaid bin Thabit and Aba Zaid.' [Bukhari, VI, No. 525.] The fact that some of the earliest historical reports make special mention in the accounts of the battles that were fought, of Muslims killed who knew (something of) the Qur'an by heart, gives a clear indication that memorization of the revelation was considered important and widely practised from the earliest times.
