Walima is a feast arranged on the occasion of marriage. The husband should invariably give the feast.
Sayyiduna Anas (radi Allahu anhu) reported that the Messenger of Allah (sallal laahu alaihi wasallam) noticed a sign of yellow colour on Abdur Rahman Bin Awf (radi Allahu anhu). He asked: “What is this?” He replied: “I have married a woman for a measure of 5 Dirhams of gold”. He said: “May Allah bless you. Give a feast even though with a goat.” (Agreed) Same reported that Sayyiduna Rasoolullah (sallal laahu alaihi wasallam) did never feed for any of his wives what he fed for Sayyidah Zainab (radi Allahu anha). He gave feast (for her marriage) with a goat. (Agreed)
Sayyiduna Abdullah Bin Omar (radi Allahu anhuma) reported that the Holy Prophet (sallal laahu alaihi wasallam) said: “Whenever one of you is invited to a feast of marriage, attend it”. (Agreed)
Sayyiduna Abu Hurayra (radi Allahu anhu) reported that the Glorious Prophet of Allah (sallal laahu alaihi wasallam) said: “The worst of feasts is a feast of marriage where the rich are invited and the poor are left. Whoso does not attend the invitation, disobeys Allah and His Prophet (sallal laahu alaihi wasallam)”. (Agreed)
