Giving
      up one’s telephone line in return for having the bill paid
Question

Is
      it permissible for a person to give up his telephone number in return for
      the person to whom he gives it up paying his bill,
      the amount of which is already known?
Praise be to Allah.I put this question
      to my shaykh, Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on
      him), who replied as follows:
 I do not see any reason why not. Giving up something is
      more general than selling. And Allaah knows best.
