Palm-reading, I-Ching, fortune telling, tea leaves as well as Zodiacal signs and Bio-rhythm computer programs, all claim to inform those who believe in them about their future. However, Allaah has stated in no uncertain terms that He alone knows the future: ''Verily the knowledge of the Hour is with Allaah alone. It is He who sends down the rain and knows the contents of the wombs. No one knows what he will earn tomorrow nor in which land he will die, but Allaah is all-knowing and aware."(Surah Luqmaan 31:34)
Therefore, Muslims must take utmost care in dealing with books, magazines, newspapers as well as individuals who, in one way or another, claim knowledge of the future or the unseen. For example, when a Muslim weather-man predicts rain, snow, or other climatic conditions for tomorrow he should add the phrase, "In ShaaAllaah (If Allaah so wishes)". Likewise, when the Muslim doctor informs her patient that she will deliver a child in 9 months or on such and such a day, she should take care to add the phrase "In ShaaAllaah", as such statements are only estimations based on statistical information.
