Hadith: The Prophet (may Allah's peace and blessings be upon him) held a wedding dinner for his marriage to one of his wives with two Mudds of barley

عن صفية بنت شيبة رضي الله عنها قالت: «أَوْلَمَ النبي صلى الله عليه وسلم على بعض نسائه بِمُدَّيْنِ من شعير».
[صحيح] - [رواه البخاري]

Safiyyah bint Shaybah (may Allah be pleased with her) reported: 'The Prophet (may Allah's peace and blessings be upon him) held a wedding dinner for his marriage to one of his wives with two Mudds of barley.
[Authentic hadith] - [Narrated by Bukhari]

Explanation

This Hadīth informs us that the Prophet (may Allah's peace and blessings be upon him) married one of the Mothers of the Believers and held a wedding dinner, for which just two Mudds of barley were cooked; nothing else was available, and this signifies the Prophet's limited resources. Nevertheless, he did not neglect this Sunnah, despite his difficult situation. And this proves that a wedding dinner can be held with less than a sheep, and also that it is valid to hold a wedding dinner with the food that is available, as one is required to offer what is within one’s ability.
