Hadith on Worship: The Prophet performs acts of worship consistently

‘Alqamah reported: I asked Aisha, “O mother of the believers, how were the deeds of the Messenger of Allah, peace and blessings be upon him? Did he designate anything for certain days?” Aisha said, “No. The Prophet would performs deeds regularly, and who among you are capable of doing as he did?”

عَنْ عَلْقَمَةَ قَالَ سَأَلْتُ عَائِشَةَ قَالَ قُلْتُ يَا أُمَّ الْمُؤْمِنِينَ كَيْفَ كَانَ عَمَلُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ هَلْ كَانَ يَخُصُّ شَيْئًا مِنْ الْأَيَّامِ قَالَتْ لَا كَانَ عَمَلُهُ دِيمَةً وَأَيُّكُمْ يَسْتَطِيعُ مَا كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَسْتَطِيعُ
