Pilgrimage is the fifth pillar of Islam and, of course, every Muslim (male/female) who has the means to go for Hajj should not delay such a duty. It should be noted that Hajj has basic requirements that must be fulfilled while performing this religious duty, such as the movement between the two mountains — As-Safa and Al-Marwah.

According to some scholars, if the pilgrim has performed Hajj without doing Tawaf Al-Wada`, then the Hajj is valid and there is no blame. It is reported that Prophet Muhammad (peace and blessings be upon him) gave permission to one of the ladies (because of her monthly period) to go home without making Tawaf Al-Wada`.

All in all, the pilgrim who misses Tawaf Al-Wada` for an acceptable reason may offer a sacrifice in Mecca, and this will not affect his or her intimate relations with his or her spouse.

In response to this question, Sheikh Ahmad Kutty,  an Islamic scholar states:

“There is a difference of opinion among scholars about the status of Tawaf Al-Wada`.
According to Maliki School of fiqh (i.e., Islamic jurisprudence), it is only one of the sunnan  (i.e., recommended rites) and therefore, one incurs no sin if he were to miss it. This is especially the case with those who have been prevented from performing it either because of not knowing its necessity or pressing circumstances.
Therefore, if you were prevented from doing it because of circumstances you had no control over, then you may follow this view, and you need not worry about it.

However, majority of scholars are of the view that Tawaf Al-Wada` is wajib (ie., obligatory). Therefore, its omission — though not invalidating Hajj — will take away its rewards; hence, it should be compensated for by offering a sacrifice. The sacrifice, however, should be done in the Haram (i.e., sacred territory). If a person is not able to perform the sacrifice because of lack of means, he or she should fast three days.
I suggest that you follow the last mentioned view if you deliberately neglected Tawaf Al-Wada`.

Regarding the assertion that a pilgrim after completing Hajj is not allowed to establish conjugal relations because of his or her failure to perform Tawaf Al-Wada`, let me state emphatically that there is no such requirement stipulated in authentic fiqh. Therefore, you need not abstain from such relations because of that.

In conclusion, if you deliberately neglected Tawaf Al-Wada`, it is best that you offer a sacrifice and it should be done in Mecca. You can get it done through someone who is living there, or anyone going there for Hajj or `Umrah.”
