question #3 Sahih al-Bukhari 6082, Book 78, Hadith 110 : How can one fulfill the obligation of a wedding banquet with limited resources?

When `Abdur-Rahman came to us, the Prophet (ﷺ) established a bond of brotherhood between him and
Sa`d bin Ar-Rabi`. Once the Prophet (ﷺ) said, “As you (O `Abdur-Rahman) have married, give a wedding
banquet even if with one sheep.”
