Narrated Aishah: The Messenger of Allah ﷺ as saying: Choose such actions as you are capable of performing, for Allah does not grow weary till you do. The acts most pleasing to Allah are those which are done most continuously, even if they amount to little. Whenever he began an action, he would do it continuously.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، ‏‏‏‏‏‏حَدَّثَنَا اللَّيْثُ، ‏‏‏‏‏‏عَنْ ابْنِ عَجْلَانَ، ‏‏‏‏‏‏عَنْ سَعِيدٍ الْمَقْبُرِيِّ، ‏‏‏‏‏‏عَنْ أَبِي سَلَمَةَ، ‏‏‏‏‏‏عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا، ‏‏‏‏‏‏أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ "اكْلَفُوا مِنَ الْعَمَلِ مَا تُطِيقُونَ، ‏‏‏‏‏‏فَإِنَّ اللَّهَ لَا يَمَلُّ حَتَّى تَمَلُّوا، ‏‏‏‏‏‏وَإِنَّ أَحَبَّ الْعَمَلِ إِلَى اللَّهِ أَدْوَمُهُ وَإِنْ قَلَّ، ‏‏‏‏‏‏وَكَانَ إِذَا عَمِلَ عَمَلًا أَثْبَتَهُ".

Narrated Aishah: The Prophet ﷺ called Uthman bin Maz'un. When he came to him, he said: Uthman, did you dislike my practice ? He said: No, by Allah, but I seek your practice. He said: I sleep, I pray, I keep fast, I (sometimes) leave fast, and I marry women. Fear Allah, Uthman, your wife has a right on you, your guest has a right on you, your self has a right on you ; you should keep fast and (sometimes) leave fast, and pray and sleep.

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ سَعْدٍ، ‏‏‏‏‏‏حَدَّثَنَا عَمِّي، ‏‏‏‏‏‏حَدَّثَنَا أَبِي، ‏‏‏‏‏‏عَنْ ابْنِ إِسْحَاقَ، ‏‏‏‏‏‏عَنْ هِشَامِ بْنِ عُرْوَةَ، ‏‏‏‏‏‏عَنْ أَبِيهِ، ‏‏‏‏‏‏عَنْ عَائِشَةَ، ‏‏‏‏‏‏أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعَثَ إِلَى عُثْمَانَ بْنِ مَظْعُونٍ، ‏‏‏‏‏‏فَجَاءَهُ، ‏‏‏‏‏‏فَقَالَ:‏‏‏‏ "يَا عُثْمَانُ، ‏‏‏‏‏‏أَرَغِبْتَ عَنْ سُنَّتِي ؟"قَالَ:‏‏‏‏ لَا وَاللَّهِ يَا رَسُولَ اللَّهِ، ‏‏‏‏‏‏وَلَكِنْ سُنَّتَكَ أَطْلُبُ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ "فَإِنِّي أَنَامُ، ‏‏‏‏‏‏وَأُصَلِّي، ‏‏‏‏‏‏وَأَصُومُ، ‏‏‏‏‏‏وَأُفْطِرُ، ‏‏‏‏‏‏وَأَنْكِحُ النِّسَاءَ، ‏‏‏‏‏‏فَاتَّقِ اللَّهَ يَا عُثْمَانُ فَإِنَّ لِأَهْلِكَ عَلَيْكَ حَقًّا، ‏‏‏‏‏‏وَإِنَّ لِضَيْفِكَ عَلَيْكَ حَقًّا، ‏‏‏‏‏‏وَإِنَّ لِنَفْسِكَ عَلَيْكَ حَقًّا، ‏‏‏‏‏‏فَصُمْ وَأَفْطِرْ، ‏‏‏‏‏‏وَصَلِّ وَنَمْ".

Alqamah said: Aishah was asked about the actions of the Messenger of Allah ﷺ. 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 ﷺ had ?

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، ‏‏‏‏‏‏حَدَّثَنَا جَرِيرٌ، ‏‏‏‏‏‏عَنْ مَنْصُورٍ، ‏‏‏‏‏‏عَنْ إِبْرَاهِيمَ، ‏‏‏‏‏‏عَنْ عَلْقَمَةَ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ سَأَلْتُ عَائِشَةَ:‏‏‏‏ كَيْفَ كَانَ عَمَلُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ؟ هَلْ كَانَ يَخُصُّ شَيْئًا مِنَ الْأَيَّامِ ؟ قَالَتْ:‏‏‏‏ لَا، ‏‏‏‏‏‏"كَانَ كُلُّ عَمَلِهِ دِيمَةً"وَأَيُّكُمْ يَسْتَطِيعُ مَا كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَسْتَطِيعُ ؟.
