Hey @sambher_shubham.
Facebook Developers - Facebook for Developers
Facebook has a special API that you can use for various purposes. This API will also provide you with easy access to any profile data, with restrictions.
You do have to keep in mind that just scraping Facebook user profiles is illegal in several countries as it is considered a privacy invasion. The fines for this are easily six figures or more, plus possible jail time if you misused the collected data. So, use the Facebook API and accept those restrictions!
Also, Facebook keeps track of all visits so if you write a Scraper outside their API, you would basically be doing a lot of page requests, which will be flagged and can result in your access to Facebook being revoked, your IP address being blocked plus a notification to the local police about suspicious hacking attempts. Don’t mess with Facebook!
