Is it halal to enter competitions where there is no outlay of money required? For example, many companies use this as a way of marketing where they can use the email address provided to enter the competition to provide more information on their products. Other companies require you to follow them on Facebook, Twitter, Instagram etc. With each of this being a competition entry. Is this like gambling or are you just participating in the marketing activity of a company as a potential customer?
Thanks for the advice
