These two treatises deal with the issue of trials and tribulation, extremely essential for every Muslim especially in the times that we are living in today. People often see, and hear of, the believers being afflicted with adversity and tribulation, and conversely they often see, and hear of the disbelievers attaining leadership and wealth in this world. This leads them to mistakenly believe that well-being in this world is only reserved for the disbelievers.
A believer may face many trials and tribulations that test his faith, patience and endurance. In a world full of conflict and war, with many also suffering from personal and family problems, shaytan causes a person to question many things. If a Muslim is tried with a difficulty, then the reasons for this are many - including one's own sin, which arise from leaving something obligated in Islam or comitting an act that is prohibited.
Trials are also a means of Allaah purifying and aiding His servants, ennobling them and granting well-being through His Wisdom. The most severely of those who were tried were the Prophets and then those closest to them in following their guidance.
