What is the ruling of having sexual intercourse with one’s wife in the direction of the Qiblah?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

There is nothing wrong with having sexual intercourse towards the direction of the Qiblah for there is no evidence preventing one from such an action and the permissibility is the basic rule here. However, it is forbidden  for Muslims to answer the call of nature towards or against the direction of the Qiblah, based on the Hadeeth. The majority of scholars confine this ruling (i.e. forbidding relieving oneself towards or against the Qiblah's direction) to the outdoors but it is permissible indoors.

Allaah Knows best.
