In the video, Mr Al-Saqaby suggests the aim of beating a wife "is to discipline, not to vent one's anger".
"The necessary Islamic conditions for beating must be met," he stresses.
The family therapist suggests the beating should not be performed with a rod or sharp object, but instead with a tooth-cleaning twig or handkerchief.
Khaled Al-Saqaby says wives should not be beaten with a rod (MEMRI)
He says: "The beating should not be performed with a rod... nor should it be a headband... or a sharp object, which, I am sad to say, some husbands use.
"It should be done with something like the sewak tooth-cleaning twig - or with a handkerchief."
He explains: "Because the goal is merely to make the wife feel that she was wrong in the way she treated her husband."
Giving the main reasons a man may beat his wife, he says the first is arguments between the wife and her husband.
"Unfortunately, some wives want to live a life of equality with their husband," he says. "This is a very grave problem."
Other women make mistakes which may lead their husbands to beat them, he adds.
Mr Al-Saqaby suggests there are some situations where a wife may hit her husband, because of his "faulty upbringing" in which he may have seen his father hit his wife and be "imitating their behaviour".
He also says he is "sad to say" some women provoke their husbands to beat them.
