Amazing is the affair of the Believer, verily all of his affair is Good – Ibn Qayyim al-Jawzeeyah
Source: From “al-Waabil as-Sayyib”
On the authority of Suhaib (may Allaah be pleased with him) he said: The Prophet (sallallaahu alayhi wa sallam said:
“Amazing is the affair of the believer, verily all of his affair is good and this is not for no one except the believer. If something of good/happiness befalls him he is grateful and that is good for him. If something of harm befalls him he is patient and that is good for him” (Saheeh Muslim #2999)
From this we understand that the state of affairs for the believer changes in the life of this world. Shaykhul Islaam ibn Qayyim al-Jawzeeyah (may Allaah have mercy upon him) said regarding the state of affairs for the believer:
“One of them is the state of (receiving a) blessing. It’s obligatory upon him (the believer) in this state (to display) the gratitude.
The second: is the state (of being) tested. It is obligatory upon him (the believer) in this state (to observe) the patience.
The third: is the state (of committing) a sin. It is obligatory upon him (the believer) in this state to seek the forgiveness from it (the sin).
The servant does not go outside of the fluctuation between these three states.
One of them is either a blessing or a virtue from Allaah of good health, wealth, a child to other than that.
It is obligatory upon him that he thanks Allaah for this bounty. Let the servant contemplate over the statement of Allaah:
” ٱعۡمَلُوٓاْ ءَالَ دَاوُ ۥدَ شُكۡرً۬اۚ وَقَلِيلٌ۬ مِّنۡ عِبَادِىَ ٱلشَّكُورُ ”
“Work you, O family of Dâwud (David), with thanks!” But few of My slaves are grateful.” (surah Sabaa: 13)
So how many of those whom Allaah has favored them:
“وَإِن تَعُدُّواْ نِعۡمَةَ ٱللَّهِ لَا تُحۡصُوهَآۗ إِنَّ ٱللَّهَ لَغَفُورٌ۬ رَّحِيمٌ۬”
“And if you would count the favours of Allâh, never could you be able to count them. Truly! Allâh is Oft-Forgiving, Most Merciful.” (surah an-Nahl: 18)
How many show thanks to Allaah for these favours? Less than a few!
Or there is a (state of being) tested.
It is obligatory upon him in this state (to observe) the patience. Meaning that Allaah from His overwhelming wisdom He could test the believing servant from the different types of test. It’s obligatory upon him to (observe) the patience because this is from the belief in the divine decree and from submitting the the decree of Allaah. Also (the servant must know) that what has befalling him was never going to pass him by. All of that is written in the book of Allaah (al-Lawhul-Mahfooth). Verily Allah doesn’t test him (the servant) to destroy him. He only test him in order to test his patience and servitude. Verily there is for Allaah upon the servant servitude in times of hardship just as there is for Him (Allaah) upon the servant servitude in times of happiness. There also is for Him (Allaah) upon the servant servitude in that which he (the servant) dislikes just as there is for Him (Allaah) upon the servant servitude in that which he (the servant) loves. Most of the creation give the servitude in that which they love. However the matter is giving the servitude in that which there is his hardship.
The other state is (a state of) sin.
It is obligatory upon him (the servant) in this state to seek the forgiveness this is clear with regards to the obligation of turning to Allaah (repentance) displaying ones need for him.”
