Prediction charts for gender

Is it sin to look at gender prediction charts like the chinese birth calender is Islam? What if someone actually follows it, is that a sin? If yes, how big of a sin is it?

Dear Brother / Sister,

As it is stated in the question, this is a case of prediction. A certain result is not and cannot be a determinant. In this situation, the intention is important. If a person believes that the result will be certain and if they use it, then they will be responsible because everything depends on Allah’s will. Even though we cannot say that they are not regarded to have committed a sin if they do not have such an intention, we do not consider it to be right for a Muslim to deal with such things. Instead, it would be better for them to open their hands to pray to Allah for what is good for them.
