Q: If I go to the website that tells you the weather, would I be falling out the fold of Islam?
A: When we get to know of the weather, then we do not place full yaqeen that it will be so. It is done merely for our information, so we know how to dress, etc. There is no harm in checking the temperature. If you wish to get a thermometer, it would also be acceptable. You do not fall out of the pale of Islam.
