The Prohibition of sodomy

It is forbidden for a Muslim man to enter his wife in her anus. This is understood from the verse quoted above (i.e. since a "planting ground" can only refer to a place where something might grow), and from the narrations cited above. There are also other hadeeth on the subject, among them:

[a] First: On the authority of Umm Salamah who said:

How he should come to her

It is allowed for a Muslim man to enter his wife in her vagina from any direction he wishes - from behind or from the front. About this Allaah revealed the following verse:

{Your wives are a tilth unto you; so approach your tilth when or how ye will} [Soorah al-Baqarah, Aayah 223]

There are also various hadeeth on this subject, of which I will give only 2:

[1] On the authority of Jaabir who said:

What to say at the time of making love

When a Muslim man is about to enter his wife, he should always say first:

Bismillaahi, Allaahumma jannibnaa ash-Shaytaan, wa jannib ash-Shaytaan maa razaqtanaa [In the name of Allaah, O Allaah, keep us away from the devil, and keep the devil away from that which You may grant us (ie. offspring).] About this, the Prophet said:

«After that, if Allaah decrees that they will have a child, the devil will never be able to harm that child.» [al-Bukhaaree]
