Regarding the Verse: "And among men is he who worships Allah's as it were on the very edge." (22.11). A man used to come to Medina as if his wife brought a son and his mares produces offspring. He would say, "This religion (Islam) is good," but if his wife did not give birth to a child and his mares produced no offspring, he would say, "This religion is bad."

“Among the worst people in status before Allah on the Day of Resurrection will be a person who loses his Hereafter for the sake of this world.”

Strange are the ways of a believer for there is good in every affair of his and this is not the case with anyone else except in the case of a believer for if he has an occasion to feel delight, he thanks (God), thus there is a good for him in it, and if he gets into trouble and shows resignation (and endures it patiently), there is a good for him in it.

Allah's Messenger (ﷺ) said, "The example of a believer is that of a fresh tender plant; from whatever direction the wind comes, it bends it, but when the wind becomes quiet, it becomes straight again. Similarly, a believer is afflicted with calamities (but he remains patient till Allah removes his difficulties.) And an impious wicked person is like a pine tree which keeps hard and straight till Allah cuts (breaks) it down when He wishes." (See Hadith No. 558, Vol. 9.)

“When Allah wants to destroy a person, He takes away modesty from him, you will only see him with the wrath of Allah upon him, and he will be hated by people. When you only see him with the wrath of Allah upon him, and hated by people, then honesty will be taken away from him, and when honesty is taken away from him, you will only see him as a traitor who is called such by others. When you only see him as a traitor who is called such by others, then mercy will be taken away from him, and when mercy is taken away from him, you will only see him as rejected and accursed, and when you only see him as rejected and accursed, then the bond of Islam will be taken away from him.”
