A Bedouin once asked the Prophet Mohammed (peace be upon him), “O Prophet Mohammed (peace be upon him), if I do the five farz (pillars) of Islam – the declaration of faith (shahada), prayer (salah), alms-giving (zakat), fasting (sawm) and pilgrimage (hajj) and I won’t do anything more or less, will you guarantee Jannah to me?”. Prophet Mohammed (peace be upon him) replied in the affirmative, i.e. said yes. So, that is it, guys and ladies. Islam is a very simple and easy religion to follow.
