Aisha, RadhiAllahu Anha, Ummul Momineen (Mother of Believers) reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, entered while I was with another woman. The Prophet, SallAllahu Alayhi Wa Sallam, said:
مَنْ هَذِهِ
Who is this?
I said, “She is a woman who never sleeps because she is always praying.” The Prophet, SallAllahu Alayhi Wa Sallam, said:
عَلَيْكُمْ مِنْ الْعَمَلِ مَا تُطِيقُونَ فَوَاللَّهِ لَا يَمَلُّ اللَّهُ حَتَّى تَمَلُّوا وَكَانَ أَحَبَّ الدِّينِ إِلَيْهِ مَا دَاوَمَ عَلَيْهِ صَاحِبُهُ
You must only perform deeds you are capable of doing. By Allah, Allah will not withhold from you until you give up. The most beloved deeds to Allah are those performed regularly.

سَدِّدُوا وَقَارِبُوا وَأَبْشِرُوا فَإِنَّهُ لَنْ يُدْخِلَ الْجَنَّةَ أَحَدًا عَمَلُهُ
Follow the right course, seek nearness to Allah, and give glad tidings. Verily, none of you will enter Paradise by his deeds alone.
They said, “Not even you, O Messenger of Allah?” The Prophet, SallAllahu Alayhi Wa Sallam, said:
وَلَا أَنَا إِلَّا أَنْ يَتَغَمَّدَنِيَ اللَّهُ مِنْهُ بِرَحْمَةٍ وَاعْلَمُوا أَنَّ أَحَبَّ الْعَمَلِ إِلَى اللَّهِ أَدْوَمُهُ وَإِنْ قَلَّ

كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا عَمِلَ عَمَلًا أَثْبَتَهُ وَكَانَ إِذَا نَامَ مِنْ اللَّيْلِ أَوْ مَرِضَ صَلَّى مِنْ النَّهَارِ ثِنْتَيْ عَشْرَةَ رَكْعَةً
If the Messenger of Allah, SallAllahu Alayhi Wa Sallam, took up a practice, he would be resolved to make it a habit. If the Prophet slept through his night prayer or he was ill, he would pray twelve cycles in the day.

‘Alqamah reported: I asked Aisha, RadhiAllahu Anha, “O mother of the believers, how were the deeds of the Messenger of Allah, SallAllahu Alayhi Wa Sallam? Did he designate anything for certain days?” Aisha, RadhiAllahu Anha, said:
لَا كَانَ عَمَلُهُ دِيمَةً وَأَيُّكُمْ يَسْتَطِيعُ مَا كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَسْتَطِيعُ
