Zubayr reported,

I saw myself with the Messenger of Allah ﷺ on the day of Uhud, when fear pressed hard upon us and Allah sent sleep over us, so that there was not one of us whose chin was not resting on his chest. By Allah, I could hear, as though in a dream, the words of Mutib bin Qushayr, "Had we had any say in the matter, we would not have been killed here." I memorized what he said, and Allah revealed concerning that, "Then, after distress, He sent down upon you security, a drowsiness" up to His words "we would not have been killed here", which was the statement of Mutib bin Qushayr, and He said, "Say, even if you had been in your houses" up to "and Allah is Knowing of what lies within the breasts" [Al Imran 3:154].

عن الزبير قال

لقد رأيتني مع رسول الله ﷺ يوم أحد حين اشتد علينا الخوف، وأرسل علينا النوم، فما منا أحد إلا وذقنه أو قال: ذقنه في صدره، فو الله إني لأسمع كالحكم قوم معتب بن قشير: لو كان لنا من الأمر شيء ما قتلنا ها هنا فحفظتها فأنزل الله عز وجل في ذلك: {ثم أنزل عليكم من بعد الغم أمنة نعاسا} إلى قوله {ما قتلنا ههنا} لقول معتب بن قشير قال: {قل لو كنتم في بيوتكم} حتى بلغ {والله عليم بذات الصدور} [سورة آل عمران: ١٥٤].
