He heard Abu Hurayrah say: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Allah, the Mighty and Majestic, said: Every deed of the son of Adam is for him, except fasting; it is for Me, and I will reward it. Fasting is a shield. So when it is the day of fasting for one of you, let him not engage in obscene speech, nor raise his voice in foolishness. If someone insults him or fights him, let him say: 'I am a fasting person.' By the One in Whose hand is the soul of Muhammad, the change in the breath of the mouth of the fasting person is more pleasant to Allah than the fragrance of musk." (1)

This hadith was also narrated from Abu Hurayrah by Sa'id ibn al-Musayyab:

2218 - Al-Rabi' ibn Sulayman informed us, saying: Ibn Wahb narrated to us, saying: Yunus informed me, from Ibn Shihab, who said: Sa'id ibn al-Musayyab narrated to me
that Abu Hurayrah said (2): I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "Allah, the Mighty and Majestic, said: Every deed of the son of Adam is for him, except fasting; it is for Me, and I will reward it. By the One in Whose hand is the soul of Muhammad, the change in the breath of the mouth of the fasting person is more pleasant to Allah than the fragrance of musk." (3)

--------------------------------------------
(1) A sound hadith, and this chain contains a divergence by Abdullah — who is Ibn al-Mubarak — from the narrators who narrated from Ibn Jurayj, for they narrated it — as mentioned in the previous narration via Hajjaj — from Ibn Jurayj, from 'Ata', from Abu Salih Dhakwan al-Samman. The author said after it in "Al-Sunan al-Kubra" (2538) and (3243): Ibn al-Mubarak is more eminent and higher in our view than Hajjaj, and the hadith of Hajjaj is more correct in our view... to the end of his words. Suwayd is Ibn Nasr.
It will also be mentioned in abbreviated form under number (2229).
(2) In (M) and (H): that he heard Abu Hurayrah say.
(3) Its chain is sound. Ibn Wahb: he is Abdullah al-Misri, and Yunus: he is Ibn Yazid al-Ayli. It is in "Al-Sunan al-Kubra" under number (2539).
It was also narrated by Muslim (1151): (161) from Harmalah, from Ibn Wahb, with this chain.
It was also narrated by Ahmad (7788), al-Bukhari (5927), and the author in "Al-Kubra" (3248) via Ma'mar, from al-Zuhri, with it.
