Sunan Abi Dawud, Hadith 1365

'Alqamah said: 'Aishah was asked about the actions of the Messenger of Allah. Did he perform some actions exclusively on some particular days ? She said: No, he performed his actions regularly. Which of you has the strength as much as the Messenger of Allah had ?

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، قَالَ ‏:‏ سَأَلْتُ عَائِشَةَ كَيْفَ كَانَ عَمَلُ رَسُولِ اللَّهِ صلى الله عليه وسلم هَلْ كَانَ يَخُصُّ شَيْئًا مِنَ الأَيَّامِ قَالَتْ ‏:‏ لاَ، كَانَ كُلُّ عَمَلِهِ دِيمَةً، وَأَيُّكُمْ يَسْتَطِيعُ مَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَسْتَطِيعُ
