Shahih Muslim - 1972

Telah menceritakan kepada kami [Abu Bakr bin Abu Syaibah] telah menceritakan kepada kami [Ghundar] dari [Syu'bah] -dalam riwayat lain- Dan Telah menceritakan kepada kami [Muhammad bin Al Mutsanna] telah menceritakan kepada kami [Muhammad bin Ja'far] telah menceritakan kepada kami [Syu'bah] dari [Ziyad bin Fayyadl] ia berkata, saya mendengar [Abu 'Iyadl] dari [Abdullah bin Amru] radliallahu 'anhuma bahwa Rasulullah shallallahu 'alaihi wasallam bersabda kepadanya: "Berpuasalah satu hari maka bagimu pahala sepanjang masa.” Abdullah bin Amru berkata, “Sesungguhnya aku masih mampu lebih dari itu.” Beliau bersabda: “Kalau begitu berpuasalah dua hari, maka bagimu pahala sepanjang masa.” Beliau bersabda: “Kalau begitu berpuasalah tiga hari (dalam setiap bulan) bagimu pahala sepanjang masa." Abdullah bin Amru berkata, "Sesungguhnya saya masih kuat lebih dari itu." beliau bersabda: "Kalau begitu, berpuasalah empat hari (dalam setiap bulannya), bagimu pahala sepanjang masa." Abdulah berkata lagi, "Saya masih kuat lebih dari itu." beliau bersabda: "kalau begitu, berpuasalah dengan seutama-utama puasa di sisi Allah yaitu puasa Dawud 'Alaihis Salam, ia berpuasa sehari dan berbuka sehari." (HR. Muslim: 1972)

Abdullah b. Amr (Allah be pleased with them) reported that the Messenger of Allah (may peace be upon him) had said to him: Observe fast for a day and there would be reward for you for the rest (of the days). He said: I am capable of doing more than this. He then said: Observe fast for two days, and there would be reward for you for the rest (of the days). He said: I am capable of doing more than this. He (the Holy Prophet) said: Observe fast for three days and there would be reward for you for the rest of the days. He said: I am capable of doing more than this, whereupon he said: Observe fast for four days and there would be reward for you for the rest of the days. He said: I am capable of doing more than this. Thereupon he said: Then observe fast (which is the) best in the eye of Allah, the fast of David (peace be upon him) ; he used to observe fast one day and break on the other day. (Muslim: 1972)
