Ibn al-Qayyim summed fifteen ways through which Allaah may dispel worries and regret.
These are as follows:
1- Tawheed al-Ruboobiyyah (belief in the Oneness of Divine Lordship)
2- Tawheed al-Uloohiyyah (belief in the Oneness of the Divine nature)
3- Tawheed of knowledge and belief (i.e., Tawheed al-Asma’ wa’l_Sifaat, belief in the Oneness of the Divine names and attributes)
4- Thinking of Allaah as being above doing any injustice to His slaves, and above punishing anyone for no cause on the part of the slave that would require such punishment.
5- The person’s acknowledging that he is the one who has done wrong.
6- Beseeching Allaah by means of the things that are most beloved to Him, which are His names and attributes. Two of His names that encompass the meanings of all other names and attributes are al-Hayy (the Ever-Living) and al-Qayyoom (the Eternal).
7- Seeking the help of Allaah Alone.
8- Affirming one’s hope in Him.
9- Truly putting one’s trust in Him and leaving matters to Him, acknowledging that one’s forelock is in His hand and that He does as He wills, that His will is forever executed and that He is just in all that He decrees.
10-Letting one’s heart wander in the garden of the Qur’aan, seeking consolation in it from every calamity, seeking healing in it from all diseases of the heart, so that it will bring comfort to his grief and healing for his worries and distress.
15-Declaring that he has no power and no strength, and leaving matters to the One in Whose hand they are.
