Dua is submitting and asking Allah for your needs. It is the most important tool available to a Muslim. Through it, a Muslim strengthens his or her relationship with the Almighty. It is unfortunate that many of us struggle though life and use all means available to us in this life to resolve our situations but neglect to ask Allah. Dua can change the Divine decree and relieve distress.

The Prophet (peace and blessings of Allah be upon him) said:

Nothing can change the Divine decree except dua. (Narrated by Ahmad, Ibn Maajah, and al-Tirmidhi.)

He also said:

. O slaves of Allaah, you must make dua. (Narrated by al-Tirmidhi)  

And he said: No precaution can protect against the decree of Allaah. Dua is beneficial with regard to what has been decreed and what has not been decreed. The dua meets the calamity that has been decreed and wrestles with it, until the Day of Resurrection. (Narrated by al-Tabaraani).

When not in calamity, we can thank Allah for what He has bestowed upon us with His blessings. The Dua's in these books available on this site will help you to ask Allah when you need Him, to remember Him and to thank Him for his blessings.
