These are a few hadiths of the Beloved Messenger of Allah (peace & blessings be upon him & his folk) on the great honor that trials, hardships, and tribulations can represent for a true believer, and how these are opportunities to exhibit one’s patience, trust, reliance, contentment, and thankfulness to Allah Most High.
34. Anas said, “I heard the Messenger of Allah, may Allah bless him and grant him peace, say, ‘Allah the Mighty and Exalted says, ‘When I test My slave regarding the two things he loves and he shows fortitude, I repay him for them with the Garden.'” He meant his eyes. [al-Bukhari]
35. ‘Ata’ ibn Abi Rabah said, “Ibn ‘Abbas said to me, ‘Shall I show you a woman who is one of the people of the Garden?’ I replied, ‘Please do.’ He said, ‘This black woman came to the Prophet, may Allah bless him and grant him peace, and said, “I have fits during which I expose myself. Pray to Allah Almighty for me.” He said, “If you wish, you can show fortitude and you will receive the Garden, and if you wish, I will pray to Allah Almighty to heal you.” She said, “I will show fortitude.” She said, “I expose myself so pray to Allah that I do not expose myself.” So he prayed for her.'” [Agreed upon]
36. Abu ‘Abdu’r-Rahman ‘Abdullah ibn Mas’ud said, “It is as if I could still see the Messenger of Allah talking about one of the Prophets, may the blessings and peace of Allah be upon them, whose people beat him, making his blood flow. While he was wiping the blood from his face, he said, ‘O Allah, forgive my people. They do not know.'” [Agreed upon]
37. Abu Sa’id and Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, “No fatigue, illness, anxiety, sorrow, harm or sadness afflicts any Muslim, even to the extent of a thorn pricking him, without Allah wiping out his mistakes by it.” [Agreed upon]
38. Ibn Mas’ud said, “I visited the Messenger of Allah, may Allah bless him and grant him peace, when he had a fever. I said, “Messenger of Allah, you have a very high fever!’ He replied, ‘Yes. I have the fever of two of you.’ I asked, ‘Is that because you will have two rewards?’ He said, ‘Yes, it is like that. No Muslim is afflicted by harm, whether it is a thorn or something worse, without Allah expiating his evil deeds on that account and his sins fall away from him like leaves from a tree.'” [Agreed upon]
39. Abu Hurayra reported that the Messenger of Allah may Allah bless him and grant him peace, said, “When Allah desires good for someone, He afflicts him.” [Al-Bukhari]
