Narrated Abu Huraira: The Prophet said, "The reciting of the Zabur (i.e. Psalms) was made easy for David. He used to order that his riding animals be saddled, and would finish reciting the Zabur before they were saddled. And he would never eat except from the earnings of his manual work."

Narrated `Abdullah bin `Amr: Allah's Apostle was informed that I have said: "By Allah, I will fast all the days and pray all the nights as long as I live." On that, Allah's Apostle asked me. "Are you the one who says: 'I will fast all the days and pray all the nights as long as I live?' " I said, "Yes, I have said it." He said, "You cannot do that. So fast (sometimes) and do not fast (sometimes). Pray and sleep. Fast for three days a month, for the reward of a good deed is multiplied by ten time, and so the fasting of three days a month equals the fasting of a year." I said, "O Allah's Apostle! I can do (fast) more than this." He said, "Fast on every third day. I said: I can do (fast) more than that, He said: "Fast on alternate days and this was the fasting of David which is the most moderate sort of fasting." I said, "O Allah's Apostle! I can do (fast) more than that." He said, "There is nothing better than that."

Narrated `Abdullah bin `Amr bin Al-As: The Prophet said to me, "I have been informed that you pray all the nights and observe fast all the days; is this true?" I replied, "Yes." He said, "If you do so, your eyes will become weak and you will get bored. So fast three days a month, for this will be the fasting of a whole year, or equal to the fasting of a whole year." I said, "I find myself able to fast more." He said, "Then fast like the fasting of (the Prophet) David who used to fast on alternate days and would not flee on facing the enemy."

And the most beloved fast is the fast of Dawud (peace be upon him). He used to sleep in the (initial) half of the night and worship during one third of the night. Then, when one sixth of the night remained, he would sleep. Similarly, he used to fast one day and not fast the next day. Ali bin al-Madini (may Allah have mercy on him) said that Aisha (may Allah be pleased with her) also said regarding this that whenever the Prophet (peace and blessings of Allah be upon him) was with me at the time of suhoor, he would be sleeping.

Narrated `Abdullah bin `Amr: Allah's Apostle 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."

Mujahid said that «فصل الخطاب‏» means understanding of judgment. «ولا تشطط‏» means do not be unjust and guide us to the straight path. "This man is my brother; he has ninety-nine «نعجة‏» (ewes)." The word «نعجة‏» is also used for a woman, and «نعجة‏» is also said for a goat. "And I have only one ewe, so he says, 'Give it to me as well.'" This is like «كفلها زكرياء‏» , meaning «ضمها» . "And he overpowers me in speech." Dawud (peace be upon him) said, "He has certainly wronged you by asking for your ewe to add to his ewes, and indeed many partners oppress one another." Up to Allah the Exalted's statement «أنما فتناه‏» . Ibn Abbas (may Allah be pleased with them both) said that ( «فتناه‏» means) We tested them. Umar (may Allah be pleased with him) used to recite it with a shaddah on the letter ta: «فتناه‏» . "So they sought forgiveness from their Lord, and they bowed and turned in repentance."

Narrated Mujahid: I asked Ibn `Abbas, "Should we perform a prostration on reciting Surat-Sa`d?" He recited (the Sura) including: 'And among his progeny, David, Solomon..(up to)...so follow their guidance (6.84-91) And then he said, "Your Prophet is amongst those people who have been ordered to follow them (i.e. the preceding apostles).

Narrated Ibn `Abbas: The prostration in Sura-Sa`d is not amongst the compulsory prostrations, though I saw the Prophet prostrating on reciting it.

Very oft-returning and attentive. The saying of Solomon: "My Lord, grant me a kingdom such as shall not belong to anyone after me." And in Surah Al-Baqarah, Allah the Exalted says: "And they followed what the devils used to recite during the reign of Solomon." And in Surah Saba, He said: "(We subjected) the wind to Solomon, its morning course was a month's journey and its evening course was a month's journey, and «قطر‏» meaning We made a fountain of molten brass flow for him ( «وأسلنا له عين القطر‏» meaning) «وأذبنا له عين الحديد» ." "And among the jinn were those who worked before him by the permission of his Lord." Until the end of the verse «من محاريب‏» . Mujahid said: «محاريب‏» are buildings that are less than palaces. «تماثيل» are images and basins, and «جواب‏» means cisterns like those made for camels. "And firmly fixed cauldrons." Until the verse «الشكور‏» . Then when We decreed death for him, nothing indicated to them his death except a creature of the earth (a termite) which was eating his staff. So when he fell down, the jinn realized that he had died. Allah the Exalted's statement until «المهين‏» . "Solomon said: I became distracted from the remembrance of my Lord because of the love of this wealth «فطفق مسحا‏» , al-kh, meaning he began to pass his hand over the manes and the forelocks and hind legs of the horses." «الأصفاد» means «الوثاق‏» shackles, chains. Mujahid said: «الصافنات‏» is derived from «صفن الفرس» , it is used when a horse stands on the tip of its hoof with one leg raised, «الجياد‏» means swift in running. «جسدا‏» means Satan (who sat on Solomon's throne wearing his ring). «رخاء‏» means gently, gladly. «حيث أصاب‏» means wherever they wished to go. «فامنن‏ أعط‏.‏‏» means, to whom He wills, He gives without account, without any hardship, without restriction.

Narrated Abu Huraira: The Prophet said, "A strong demon from the Jinns came to me yesterday suddenly, so as to spoil my prayer, but Allah enabled me to overpower him, and so I caught him and intended to tie him to one of the pillars of the Mosque so that all of you might see him, but I remembered the invocation of my brother Solomon: 'And grant me a kingdom such as shall not belong to any other after me.' (38.35) so I let him go cursed."
