:salamext:
Strive to do good deeds, be patient, seek help from Allah through patience and prayer and read the Qur'an often because Allah says "Verily, in the remembrance of Allah do hearts find rest" [13:28]. The Qur'an tells you the state of people who are in loss, and those who are in success.
Allah says about those who have succeded:
Whoever works righteousness — whether male or female — while he (or she) is a true believer (of Islamic Monotheism) verily, to him We will give a good life (in this world with respect, contentment and lawful provision), and We shall pay them certainly a reward in proportion to the best of what they used to do. [16:79]
Ibn Katheer (rahimullah) said:
This is a promise from Allah to the one who does righteous deeds that Allah will give him a good life in this world and a good life includes all kinds of comfort and delight. It was narrated from Ibn Abbas and others that they interpreted it as meaning a goodly permissible provision, and it was narrated from Ali ibn Abi Talib (r) that he interpreted it as meaning contentment. Ali ibn Abi Talhah said, narrating from Ibn Abbas, that it means happiness. The correct view is that a good life includes all of these things. [Tafseer al-Qur’aan il-Azeem (4/601)].
And Allah says in Surah Mulk about those who have lost:
But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? [67:17]
And He says in Surah ar-Room:
"They know only the outside appearance of the life of the world, and they are heedless of the Hereafter." [30:7]
And Ibn al-Qayyim summerised fifteen ways through which Allaah may dispel worries and regret. These are as follows:
1- Tawheed al-Rubobiyyah (belief in the Oneness of Divine Lordship)
2- Tawheed al-Ulohiyyah (belief in the Oneness of the Divine nature)
3- Tawheed of knowledge and belief (i.e. Tawheed al-Asma wa Sifaat, belief in the Oneness of the Divine names and attributes)
4- Thinking of Allah 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 Allah 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'an, 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.
11- Seeking forgiveness.
12- Repentance.
13- Jihad.
14- The Prayer
15- Declaring that he has no power and no strength, and leaving matters to the One in Whose hand they are.
