The believer remains free from the extremes of happiness that cause one to forget God and the extremes of sadness that causes the ignorant to lose hope and blame God.
“How wonderful is the affair of the believer, for his affairs are all good, and this applies to no one but the believer. If something good happens to him, he is thankful for it and that is good for him. If something bad happens to him, he bears it with patience and that is good for him.”
– (Narrated by Muslim, 2999).
