We should know that Allah has created us to live an eternal life with no death, a life of pride and ease with no humiliation, a life of security with no fear, a life of richness with no poverty, a life of joy with no pain, a life of perfection with no flaws. Allah is testing us in this world with a life that will end in death, a life of pride that is accompanied by humiliation and degradation, a life that is tainted by fear, where joy and ease are mixed with sorrow and pain.
Ibn Qayyim Al-JawziyyaA true believer does not fear physical death, rather he fears the death of his heart
Ibn Qayyim Al-JawziyyaAnd verily for everything that a slave loses there is a substitute, but the one who loses Allah will never find anything to replace Him.
Ibn Qayyim Al-JawziyyaFrom the perfection of Allah's ihsan is that He allows His slave to taste the bitterness of the break before the sweetness of the mend. So He does not break his believing slave, except to mend him. And He does not withhold from him, except to give him. And He does not test him (with hardship), except to cure him.
Ibn Qayyim Al-Jawziyya
