Is it obligatory for a Muslim to recite the Quran or this is solely a recommended act (except in Salah)?

I have heard many traditions concerning reciting the Noble Quran and I know it has much thawab if we recite it. For instance, there is a narration from the apostle of Allah (pbuh) that said: > Whoever recites a letter from the Holy Quran, it will be written for > him a Hassanah that 10 times has more thawab… (Majma'ul Bayan p. 36) Or in another tradition, the Prophet (peace be upon him and his household) said: > the best Ebadah of my Ummah is reciting of the Quran. (Wasaelul-Shia, > vol. 6, p. 168) But I wonder if it is mandatory (wajib) for a Muslim to recite it or it is just as a recommended practice (except reciting the Quran during the salah)
