14 Nov How to make Dua: Tip #14
A Muslim must prioritise what needs to be done in life, for example Dua should not interfere with performing the obligatory prayers, as the obligatory actions are more important than the voluntary.
Without doubt, Dua is one of the most important acts of worship, however, worship can be divided into two categories: those that have a specific time, and those that can be done at any time. Dua is of the second category, in that there is no specific time of the day when making it is restricted. Salah is of the first category, so Dua should not be done at the expense of missing ones Salah.
The first category takes precedence, this is proven in the Hadith of the Prophet [May the Peace and Blessings of Allah be upon him] in which he narrated to us about the story of Jurayj, a monk who chose to pray instead of answering his Mothers request, when he could have shortened it, this resulted in his Mother making dua against him.
