Is it permissible for an unmarried person to read the questions about nikah? Is medical insurance from a medical factory allowed?

1. It is permissible.
2. The permissibility or otherwise of an insurance policy depends on the terms and insurance policy scheme. But leaving aside mutual insurance schemes, all the insurance policies available with the traditional insurance companies run on a commercial basis and contain elements of interest or Qimar (chance) or both, hence, not allowed. (Contemporary Fataawa; Mufti Taqi Usmani)
