Dua is asking Allah for help or for the fulfilment of a particular need. It expresses a slave's helplessness and dependence on Allah, the All-Powerful and Merciful. It is the channel through which one gets directly in touch with one's Creator.
The purpose of man's creation is worship and according to a Hadeeth, 'dua is the essence of worship'. (Tirmizi) And according to another Hadeeth, 'dua is the worship'. (Tirmizi)
Just as Salãh, Sawm, Zakãh, Hajj etc. are acts of worship, dua too is an act of worship. Therefore just as one takes out time to pray Salãh or to recite the Qur'ãn or make zikr, similarly, according equal importance to dua, one should also take out sufficient time for the sake of dua.
