Uthman bin Mawhab reported,

A man came to perform the pilgrimage at the House. He saw a group of people sitting and asked, "Who are these people seated here?"They replied, "These are Quraysh."He asked, "Who is the elder among them?"They said, "Ibn Umar."So he approached him and said, "I want to ask you about something. Will you answer me?"He continued, "I adjure you by the sanctity of this House, do you know that Uthman fled on the day of Uhud?"Ibn Umar said, "Yes."The man asked, "Do you know that he was absent from Badr and did not witness it?"Ibn Umar said, "Yes."The man asked, "Do you know that he stayed behind from the Pledge of Ridwan and did not witness it?"Ibn Umar said, "Yes."The man exclaimed, "Allahu Akbar!"Ibn Umar said, "Come, let me inform you and clarify for you what you have asked about. As for his fleeing on the day of Uhud, I bear witness that Allah has pardoned him for it. As for his absence from Badr, the daughter of the Messenger of Allah ﷺ was his wife and she was ill, so the Prophet ﷺ said to him, 'You will have the reward of one who witnessed Badr and his share of the spoils.' As for his absence from the Pledge of Ridwan, if there had been anyone in the heart of Mecca more honored than Uthman bin Affan, the Prophet would have sent him in his place. So he sent Uthman. The Pledge of Ridwan took place after Uthman had departed for Mecca. The Prophet ﷺ then raised his right hand and said, 'This is the hand of Uthman,' and he struck it against his other hand and said, 'This is on behalf of Uthman.' Now go with this answer."

Sahih

عن عثمان بن موهب قال

جاء رجل حج البيت فرأى قوما جلوسا فقال: من هؤلاء القعود؟ قالوا: هؤلاء قريش، قال: من الشيخ؟ قالوا: ابن عمر، فأتى فقال: إني سائلك عن شيء أتحدثني؟ قال: أنشدك بحرمة هذا البيت، أتعلم أن عثمان فر يوم أحد؟ قال: نعم، قال: فتعلمه تغيب عن بدر فلم يشهدها؟ قال: نعم، قال: فتعلم أنه تخلف عن بيعة الرضوان فلم يشهدها؟ قال: نعم قال: فكبر، قال ابن عمر: تعال لأخبرك ولأبين لك عما سألتني عنه: أما فراره يوم أحد فأشهد أن الله عفاعنه، وأما تغيبه عن بدر فإنه كان تحته بنت رسول الله ﷺ وكانت مريضة، فقال له النبي ﷺ: إن لك أجر رجل ممن شهد بدرا وسهمه وأما تغيبه عن بيعة الرضوان فإنه لو كان أحد أعز ببطن مكة من عثمان بن عفان لبعثه مكانه، فبعث عثمان، وكانت بيعة الرضوان بعد ما ذهب عثمان إلى مكة، فقال النبي ﷺ بيده اليمنى: هذه يد عثمان، فضرب بها على يده فقال: هذه لعثمان اذهب بهذا، الآن معك.
