Is the story about the Muslim killing his wife and burying his two girls alive because the wife was reading the Bible true?

No it isn't (According to Snopes)

Explanation:

The story relates to a purported report that appeared in Egypt in 2004 that was updated in 2007 about a man who killed his wife and buried their 2 daughters aged 8 years and the other an infant, alive because the wife was reading The Bible.

The story goes on to say that the girls were kept alive under the sand for 15 days until their rescue and when interviewed they described a figure with a resemblance to Jesus Christ feeding and taking care of them.

The Snopes website found no evidence of this being true because there were no news reports of the incident having happened in Egypt despite the story saying there were.
