Qays bin Marwan reported,

He came to Umar and said, "Commander of the Faithful, I have come from Kufa, where I left behind a man dictating copies of the Quran from memory."Umar grew angry and swelled with rage until he nearly filled the space between the two crossbars of the saddle. He said, "Woe to you, who is he?"The man replied, "Abdullah bin Masud."His anger gradually subsided and faded away until he returned to his normal state. Then he said, "Woe to you, by Allah, I do not know of anyone left among the people more deserving of that than him, and I will tell you why.The Messenger of Allah ﷺ used to stay up late at night with Abu Bakr discussing matters concerning the Muslims. One night he stayed late with him while I was present. Then the Messenger of Allah ﷺ went out, and we went out with him. Suddenly there was a man standing and praying in the mosque. The Messenger of Allah ﷺ stood listening to his recitation. When we were just about to recognize him, the Messenger of Allah ﷺ said, 'Whoever wishes to recite the Quran fresh as it was revealed, let him recite it according to the recitation of Ibn Umm Abd.'Then the man sat down to make supplication, and the Messenger of Allah ﷺ began saying to him, 'Ask and you will be given. Ask and you will be given.'"Umar said, "I told myself, by Allah, I will go to him in the morning and give him the good news. So I went to him in the morning to deliver the good news, but I found that Abu Bakr had beaten me to him and had already told him. By Allah, I never raced him to any good deed except that he beat me to it."

Sahih

عن قيس بن مروان

أنه أتى عمر فقال: جئت يا أمير المؤمنين من الكوفة، وتركت بها رجلا يملي المصاحف عن ظهر قلبه، فغضب وانتفخ حتى كاد يملأ ما بين شعبتي الرحل، فقال: ومن هو ويحك؟ قال: عبد الله بن مسعود، فما زال يطفأ ويسرى عنه الغضب حتى عاد الى حاله التي كان عليها. ثم قال: ويحك والله ما أعلمه بقي من الناس أحد هو أحق بذلك منه، وسأحدثك عن ذلك، كان رسول الله ﷺ لا يزال يسمر عند أبي بكر الليلة كذاك في الأمر من أمر المسلمين، وإنه سمر عنده ذات ليلة وأنا فخرج رسول الله ﷺ وخرجنا معه، فإذا رجل قائم يصلي في المسجد، فقام رسول الله ﷺ يستمع قراءته، فلما كدنا أن نعرفه قال رسول الله ﷺ: من سره أن يقرأ القرآن رطبا كما أنزل فليقرأه على قراءة ابن أم عبد. قال: ثم جلس الرجل يدعو فجعل رسول الله ﷺ يقول له: سل تعطه سل تعطه. قال عمر: قلت والله لأغدون إليه فلا بشرنه، قال: فغدوت إليه لأبشره فوجدت أبا بكر قد سبقني إليه فبشره، ولا والله ما سابقته إلى خير قط إلا سبقني إليه.
