Sayyiduna Abu Hurairah (may Allah be pleased with him) says: Umm Abdullah bint Abu Dhibab was ill, so I went to her to visit her. She said: O Abu Hurairah! Once I went to visit Sayyidah Umm Salamah (may Allah be pleased with her), who was sick. She saw a boil on my hand and said that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "When Allah the Exalted tests a servant and he dislikes it due to his condition and state, then Allah the Exalted makes that hardship an expiation for his sins and a means of purifying him, as long as he does not present it at the door of anyone other than Allah (for cure) or call upon anyone other than Allah to remove it."

Abu Ash’ath San’ani says: I went towards the mosque of Damascus and I went early. I met Shaddad bin Aws (may Allah be pleased with him), and with him was Sanabahi. I asked them: May Allah have mercy on you, where are you intending to go? They said: We are going to visit a sick brother of ours. (Hearing this) I also went along with them. We reached the patient. Both of them asked him: How are you? He replied: By the grace and kindness of Allah. Sayyiduna Shaddad (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said:“Allah the Exalted says: When I test My believing servant and he remains patient over My trial while praising Me, then (when he recovers and) rises from his bed, he is as free from sin as the day his mother gave birth to him. Furthermore, Allah the Exalted says to the angels who record deeds: I have confined My servant and am testing him, so continue to record for him the same (good deeds) that you used to record for him when he was healthy (even though he is not performing those deeds now).”

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "The increase in reward and recompense is in accordance with the increase in trials (that is, the greater the trial, the greater its reward). And when Allah Almighty loves a people, He subjects them to trials. So whoever shows patience and acceptance in it, for him is (Allah's) pleasure, and whoever expresses displeasure and anger towards Allah because of it, for him is (Allah's) displeasure."

It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said:“(Various matters) continue to become expiation for the believer (for his sins).”

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "A high rank is decreed for a man by Allah Almighty, but he does not attain it through his deeds. Therefore, Allah Almighty continues to test him with trials that he dislikes, until he reaches his (appointed) rank."

Sayyiduna Abu Hurairah (may Allah be pleased with him) reports: A woman afflicted with insanity came to the Noble Prophet (peace and blessings of Allah be upon him) and said: O Messenger of Allah! Pray to Allah that He grants me healing. The Prophet (peace be upon him) said: "If you wish, I will pray and Allah will grant you healing, and if you wish, be patient, (as a result of which) there will be no reckoning for you."

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) came to Umm Sa’ib or Umm Musayyib and asked: "Umm Sa’ib! What has happened to you? You are trembling." She replied: "It is fever, may Allah not bless it." The Prophet (peace and blessings be upon him) said: "Do not speak ill of fever, for it removes the sins of the children of Adam just as a bellows removes the impurities of iron."

It is narrated from Sayyiduna Bara’ bin ‘Azib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said:“Whenever a vein or an eye is harmed, it is due to some sin, but the pains that Allah, the Exalted, keeps averting (from a person) are much more.”

It is narrated from Sayyiduna Uqbah bin Amir al-Juhani, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "There is no deed on any day except that the doer’s end is upon that deed. (Its explanation is that) when a believer becomes ill, the angels say to Allah Almighty: 'O our Lord! You have prevented so-and-so servant (from performing deeds).' (So what should be done about his good deeds?) Allah Almighty replies: 'Count for this servant the same deeds as he used to do (before falling ill), until he recovers or passes away.'"

It is narrated from Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) that a man came to the Noble Prophet (peace and blessings be upon him) and said: "O Messenger of Allah! By Allah! I love you." (Upon hearing this) the Messenger of Allah (peace and blessings be upon him) said: "Trials descend upon those who love me just as the flow of a flood swiftly reaches its end."
