Etiquettes of Dua’a and the times and places of acceptance
Dua'a is a great act of Ibadah (worship), which Allah has granted to the ummah (followers) of Rasul (S). It is an act of Ibadah which creates a direct link between a person and Allah. It makes a person realize that Allah is the only One who can fulfil his needs.
Imam Suyuti Says in the introduction
'There are many motivating factors for the acceptance of Dua'a Either there us a quality in the person making Dua'a, some virtues regarding the time, some importance concerning the place or some loftiness in the wordings of Dua'a which occur in the noble Ahadeeth'
