When we dispatched the caravan, Abu Dawud meaning toward Medina, he said, I used to deliver admonitions after the dawn prayer and then prostrate. Ibn Umar forbade me from doing so, but I did not stop, three times.Then he came back and said, "I prayed behind the Messenger of Allah ﷺ, and with Abu Bakr and Umar and Uthman , and they did not prostrate until the sun had risen."
حدثنا عبد الله بن الصباح العطار حدثنا أبو بحر حدثنا ثابت بن عمارة
لما بعثنا الركب قال أبو داود يعني إلى المدينة قال كنت أقص بعد صلاة الصبح فأسجد فنهاني ابن عمر فلم أنته ثلاث مرار ثم عاد فقال إني صليت خلف رسول الله ﷺ ومع أبي بكر وعمر وعثمان رضي الله عنهم فلم يسجدوا حتى تطلع الشمس
Isnad daif. Bayhaqi (2/326) narrated it from the hadith of Abu Dawud through the same route. Abu Bahr Abdul-Rahman bin Uthman is daif (Taqrib). Ahmad (2/24, 106) narrated it from Waki, from Thabit bin Umara, through the same route, with the wording, "I prayed with the Messenger of Allah ﷺ, Abu Bakr, Umar, and Uthman, and there is no prayer after dawn until the sun rises." Its isnad is hasan.
