As-salāmu ʿalaykum Ustadh. When registering on some websites, we're sometimes required to tick a box that says e.g., "I have read and accept the terms and conditions." However sometimes they are really long and complex. Is it mandatory to read the terms and conditions before agreeing to them?

It is not mandatory, that is your choice, you can read or jave someone explain them to u.
