Messenger of Allah ﷺ said to me, "The most beloved fasting to Allah was the fasting of (the Prophet) David who used to fast on alternate days. And the most beloved prayer to Allah was the prayer of David who used to sleep for (the first) half of the night and pray for 1/3 of it and (again) sleep for a sixth of it."  

لِي رَسُولُ اللَّهِ ﷺ أَحَبُّ الصِّيَامِ إِلَى اللَّهِ صِيَامُ دَاوُدَ كَانَ يَصُومُ يَوْمًا وَيُفْطِرُ يَوْمًا وَأَحَبُّ الصَّلاَةِ إِلَى اللَّهِ صَلاَةُ دَاوُدَ كَانَ يَنَامُ نِصْفَ اللَّيْلِ وَيَقُومُ ثُلُثَهُ وَيَنَامُ سُدُسَهُ  

The best fasting in the eye of Allah is that of David, for he fasted for half of the age (he fasted on alternate days), and the best prayer in the eye of Allah, the Exalted and Majestic, is that of David (peace be upon him), for he slept for half of the night and then stood for prayer and then again slept. He prayed for one-third of the night after midnight. He (the narrator) said: I asked 'Amr b. Dinar whether 'Amr b. Aus said that he stood for prayer one-third of the night after midnight. He said: Yes.  

أَنَّ النَّبِيَّ ﷺ قَالَ أَحَبُّ الصِّيَامِ إِلَى اللَّهِ صِيَامُ دَاوُدَ كَانَ يَصُومُ نِصْفَ الدَّهْرِ وَأَحَبُّ الصَّلاَةِ إِلَى اللَّهِ ﷻ صَلاَةُ دَاوُدَ عَلَيْهِ السَّلاَمُ كَانَ يَرْقُدُ شَطْرَ اللَّيْلِ ثُمَّ يَقُومُ ثُمَّ يَرْقُدُ آخِرَهُ يَقُومُ ثُلُثَ اللَّيْلِ بَعْدَ شَطْرِهِ قَالَ قُلْتُ لِعَمْرِو بْنِ دِينَارٍ أَعَمْرُو بْنُ أَوْسٍ كَانَ يَقُولُ يَقُومُ ثُلُثَ اللَّيْلِ بَعْدَ شَطْرِهِ قَالَ نَعَمْ  

“The most beloved fast to Allah is the fast of Dawud, for he used to fast one day and not the next. And the most beloved of prayer to Allah is the prayer of Dawud; he used to sleep half of the night, pray one-third of the night and sleep one-sixth of the night.”  

قَالَ رَسُولُ اللَّهِ ﷺ أَحَبُّ الصِّيَامِ إِلَى اللَّهِ صِيَامُ دَاوُدَ كَانَ يَصُومُ يَوْمًا وَيُفْطِرُ يَوْمًا وَأَحَبُّ الصَّلاَةِ إِلَى اللَّهِ صَلاَةُ دَاوُدَ كَانَ يَنَامُ نِصْفَ اللَّيْلِ وَيُصَلِّي ثُلُثَهُ وَيَنَامُ سُدُسَهُ

And the most beloved prayer to Allah was the prayer of David who used to sleep for (the first) half of the night and pray for 1/3 of it and (again) sleep for a sixth of it." (Using translation from Bukhārī 3420)  

عَنِ النَّبِيِّ ﷺ قَالَ «أَحَبُّ الصَّلَاةِ إِلَى اللَّهِ صَلَاةُ دَاوُدَ كَانَ يَنَامُ نِصْفَ اللَّيْلِ وَيَقُومُ ثُلُثَ اللَّيْلِ وَيَنَامُ سُدُسَهُ وَأَحَبُّ الصِّيَامِ إِلَى اللَّهِ صِيَامُ دَاوُدَ كَانَ يَصُومُ يَوْمًا وَيُفْطِرُ يَوْمًا»

And the most beloved prayer to Allah was the prayer of David who used to sleep for (the first) half of the night and pray for 1/3 of it and (again) sleep for a sixth of it." (Using translation from Bukhārī 3420)  

قَالَ رَسُولُ اللهِ ﷺ «أَحَبُّ الصِّيَامِ إِلَى اللهِ صِيَامُ دَاوُدَ كَانَ يَصُومُ يَوْمًا وَيُفْطِرُ يَوْمًا وَأَحَبُّ الصَّلَاةِ إِلَى اللهِ صَلَاةُ دَاوُدَ كَانَ يَنَامُ نِصْفَ اللَّيْلِ وَيَقُومُ ثُلُثَهُ وَيَنَامُ سُدُسَهُ»

The Messenger of Allah ﷺ said to me: The fast most liked by Allah is the one observed by Dawud (David), and the prayer dearer to Allah is the one offered by Dawud (David): he would sleep half the night, and stand (in prayer) one-third of it, and sleep one-sixth of it. He would go without fasting one day, and fast the other day. (Using translation from Abū Dāʾūd 2448)   

"أحبُّ الصيام إلى اللهِ: صيامُ داودَ، كان يصومُ يومًا ويُفْطِرُ يومًا، وأحبُّ الصلاةِ إلى اللهِ: صلاةُ داودَ، كان ينام نصف اللَّيْل وبقوم ثلثه وينام سُدُسَه" .
