Meaning of itikaf is farz or sunnah?

Answer By Dr Zakir Naik,As we mentioned earlier the recommended acts while doing Ietikaaf is to offer Salaah, to do Nawafil Salaah, to.. supplication, to ask for forgiveness, to do Dhikr and to read the Qur’an. So it’s preferable to do these acts. But if someone really wants to learn something, specially of Islam and if you teach there’s no problem or if you give a lecture or you give a lesson to someone specially regarding the ruling of Islam, it’s permitted… fine because you’re teaching someone getting him closer to Allah (Subhanahu wa ta’ala).
