Be generous in celebrations; Establish strong bonds of brotherly love/sisterhood; Make sure everyone can enjoy special occasions without feeling left out due to lack of resources or money

The hadith narrated by Anas tells us about the importance of celebrating weddings with generosity. It is narrated that when 'Abdur-Rahman came to the Prophet's company, he established a bond of brotherly love between him and Sa'd bin Ar-Rabi'. This shows us how important it is for Muslims to have strong bonds of brotherhood and sisterhood. Furthermore, the Prophet encouraged 'Abdur-Rahman to give a wedding banquet even if it was with one sheep. This teaches us that we should be generous in our celebrations no matter what our financial situation may be. We should always strive to make sure that everyone can enjoy special occasions like weddings without feeling left out due to lack of resources or money.
