There are several methods of earning income online now, and many people are profiting. I am also thinking of getting involved, but I don't know whether these commercial transactions are lawful in Islam. Some of the ways of earning are as follows:
1) Affiliate programs : In these programs, some other online merchant’s products are sold via your website, and that merchant will give you a commission for each sale.
2) There are some programs whereby, if you send someone to the merchant’s link, he will be tracked by cookies, and if that person purchases anything, you will be given a commission on those purchases.
2)Internet Referrals: In this arrangement, if you refer someone to a site, you will be paid for the referral itself. This can be a “pay per click” scheme. In this arrangement, an ad is placed on your website, and if somebody clicks on that ad, you will be paid a fixed rate for that.
