Abū ʿAbd al-Raḥmān said: Abū ʿAmmār's name is ʿArīb ibn Ḥumayd, and ʿAmr ibn Shuraḥbīl is known by the kunya Abū Maysarah. Salamah ibn Kuhayl differed from al-Ḥakam in his chain of transmission, and al-Ḥakam is more reliable than Salamah ibn Kuhayl.(1)

36 - Chapter: The Measure of Zakāt al-Fiṭr

2508 - Muḥammad ibn al-Muthannā informed us, saying: Khālid — namely Ibn al-Ḥārith — narrated to us, saying: Ḥumayd narrated to us, from al-Ḥasan, who said:

Ibn ʿAbbās — while he was the governor of Baṣrah — said at the end of the month: "Bring forth the zakāh of your fast." The people then looked at one another, so he said: "Who among those present here is from the people of Madīnah?"

(1) The men of this chain of transmission are trustworthy; Sufyān is al-Thawrī. It appears in al-Sunan al-Kubrā under number (2298). The narration of Salamah ibn Kuhayl here is, according to al-Bukhārī, more plausible than the narration of al-Ḥakam ibn ʿUtaybah mentioned before it, contrary to what the author held.

Aḥmad (23843) and Ibn Mājah (1828) also transmitted it via Wakīʿ, with this chain of transmission.

Aḥmad also transmitted it (23840), as did al-Tirmidhī in al-ʿIlal al-Kabīr (205) and al-Bayhaqī in al-Sunan al-Kubrā 4/159, through multiple paths from Sufyān al-Thawrī, with the same content, and in Aḥmad's version there is an addition mentioning the fast of ʿĀshūrā'.

Al-Ḥāfiẓ Ibn Ḥajar strengthened its chain of transmission in al-ʿUjāb 1/430 and declared it authentic in Fatḥ al-Bārī 3/267.

Al-Tirmidhī asked al-Bukhārī about this ḥadīth of Salamah ibn Kuhayl and the ḥadīth of al-Ḥakam ibn ʿUtaybah that preceded it, and al-Bukhārī said: "I have not heard anyone give a ruling on this matter, except that the ḥadīth of Salamah ibn Kuhayl is more plausible to me — however, this contradicts what is narrated from the Prophet ﷺ regarding zakāt al-fiṭr. Ibn ʿUmar said: 'The Messenger of Allah ﷺ made zakāt al-fiṭr obligatory…'" The ḥadīth of Ibn ʿUmar has already preceded under numbers (2500–2505).

Al-Bayhaqī said following the ḥadīth: "This does not indicate the abrogation of its obligation, for the revelation of one obligation does not necessitate the abrogation of another. The scholars are unanimous on the obligation of zakāt al-fiṭr, even if they differ on whether it is called an obligation (farḍ). It is not permissible to abandon it, and with Allah is success."
