Prayer of one who does not shave his pubic hair

Praise be to Allah.

Shaving the pubic hair – the hair that grows around the private    parts – is part of the sunan al-fitrah (actions that befit the natural state of man). They should not be left without shaving for more than forty days because of the proven hadeeth to that effect. However, leaving them for more than forty days does not have any effect on the validity of a person’s prayer, and to say that it does reflects ignorance of the pure sharee’ah.
