If      the child of zinaa is present, will he be a chaperone for the two whocommitted zinaa?
Question

If one has a child with a woman, and not married to them is it permissable for them to be alone with one another (not being married at the time of conception or after the birth) The 3rd party will always be shayton, and are children suitable chaparones.
Praise be to Allah.We put this question to Shaykh ‘Abd-Allah ibn Jibreen, who replied:
 They will no longer be counted as being alone together (khulwah) if there is a third person present with them, whether he is their child or someone else’s, and whether he is the child of zinaa or the child of a legitimate marriage – on the condition that he is above the age of discretion and is of sound mind, that there is no fear of fitnah, and that the woman is wearing full hijaab.
