Walimah

After the first night, to invite one’s friends, relatives, family and the poor for the Walimah is Sunnah. It is not necessary to prepare a great amount of food. A little food prepared according to one’s means and feed a few relatives or friends will suffice in fulfilling the Sunnah.

The worst Walimah is that where only the rich and the irreligious are invited and the poor, destitute and the pious are left out.
