It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“It is from the good fortune of the son of Adam that he seeks goodness from Allah Almighty, and it is also from the good fortune of the son of Adam that he is pleased with the decision of Allah Almighty. And it is from the misfortune of the son of Adam that he does not seek goodness from Allah Almighty, and it is also from his wretchedness that he is displeased with the decision of Allah Almighty.”

Sayyiduna Suhaib bin Sinan (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "I am amazed at the affair of the believer, for verily all of his affair is good, and this (honor) is for no one except the believer. If something pleasing befalls him and he is grateful, then that is better for him; and if something harmful befalls him and he is patient, then that is better for him."

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Wondrous is the case of the believer; whatever decision Allah makes for him, there is good in it for him."
