Sa'd said that when the Prophet was asked which people suffered the greatest affliction he replied, “The prophets, then those who come next to them, then those who come next to them. A man is afflicted in keeping with his religion; if he is firm in his religion his trial is severe, but if there is weakness in his religion it is made light for him, and it continues like that till he walks on the earth having no sin.”Tirmidhi, Ibn Majah and Darimi transmitted it, and Tirmidhi said this is a hasan sahih tradition.

‘A isha said, “I do not envy anyone an easy death after having seen the severity of the death of God’s messenger.” Tirmidhi and Nasa’i transmitted it.

I saw the Prophet when he was dying. He had a drinking-cup containing water, and he would put his hand into the cup, then wipe his face, then say, “O God, help me to bear the evils of death,” or, “the pangs of death.” Tirmidhi and Ibn Majah transmitted it.

Anas reported God’s messenger as saying, “When God has a good purpose towards His servant He gives him punishment beforehand in this world, but when He has an evil purpose towards His servant He refrains from dealing with his sin till He takes from him full payment for it on the day of resurrection.” Tirmidhi transmitted it.

He reported God’s messenger as saying, “The magnitude of the reward goes along with the magnitude of the affliction. When God who is great and glorious loves people He afflicts them, and those who accept it gladly receive God’s good pleasure, but those who are displeased receive God’s displeasure. Tirmidhi and Ibn Majah transmitted it.

Abu Huraira reported God’s messenger as saying, “The believing man or woman continues to have affliction in person, property and children so that they (this is a little difficult to translate. The Arabic has “he”, but the pronoun refers to the man or woman mentioned. I have therefore compromised by using the plural) may finally meet God free from sin.” Tirmidhi transmitted it, and Malik transmitted something similar. Tirmidhi said this is a hasan sahih tradition.

Muhammad b. Khalid as-Sulami on his father’s authority said his grandfather reported God’s messenger as saying, “When God has previously decreed for a servant a rank which he has not attained by his action, He afflicts him in his body, or his property, or his children. He then enables him to endure that so that He may bring him to the rank previously decreed for him by God.” Ahmad and Abu Dawud transmitted it.

‘Abdallah b. [ash-] Shikhkhir reported God’s messenger as saying, “The son of Adam was created with ninety-nine trials at his side. If the trials miss him he falls into decrepitude till he dies.” Tirmidhi transmitted it, saying that this is a gharib tradition.

Jabir reported God’s messenger as saying, "On the day of resurrection, when people who have suffered affliction are given their reward, those who are healthy will wish their skins had been cut to pieces with scissors when they were in the world.” Tirmidhi transmitted it, saying that this is a gharib tradition.

‘Amir ar-Ram told that God’s messenger mentioned illnesses and said, "When a believer is afflicted by illness and God who is great and glorious cures him of it, it serves as an atonement for his previous sins and a warning to him for the future; but when a hypocrite becomes ill and then is cured he is like a camel which has been tethered and then let loose by its owners, but does not know why they tethered it and why they let it loose.” When a man asked God’s messenger what illnesses were, adding that he swore by God he had never been ill, he said, "Get up and leave us ; you do not belong to our number.”Abu Dawud transmitted it.

Abu Sa'id reported God’s messenger as saying, "When you go in to visit an invalid, express a hope that he will live long. That will not avert anything, but it will comfort him.” Tirmidhl and Ibn Majah transmitted it, and Tirmidhi said this is a gharib tradition.

Sulaiman b. Surad reported God’s messenger as saying, "He who dies of an internal trouble will not be punished in his grave.” Ahmad and Tirmidhi transmitted it, the latter saying this is a gharib tradition.

Anas told that when a young Jew who was a servant of the Prophet became ill the Prophet went to visit him and, sitting down by his head, said to him, “Accept Islam.” He looked at his father who was beside him, and he said, "Obey Abul Qasim.” So he accepted Islam, and the Prophet went out saying, "Praise be to God who has saved him from hell.” Bukhari transmitted it.

Abu Huraira reported God’s messenger as saying, '"If anyone visits an invalid, one cries out from heaven, ‘May you be good, may your walk be good, and may you come to an abode in paradise!”’ Ibn Majah transmitted it.

This black woman came to the Prophet and said, “Messenger of God, I am subject to fits and become uncovered, so make supplication to God for me.” He replied, “If you wish you may endure it and be rewarded with paradise, but if your wish I shall make supplication to God to cure you.” She said, “I shall endure it.” Then she added, “But since I become uncovered, make supplication to God that that may not happen.” He then made supplication for her. (Bukhari and Muslim.)

Yahya b. Sa'id said that when a certain man died in the time of God’s messenger another said, “Congratulations to him! He has died without being afflicted by illness.” God’s messenger then said, “I’m sorry for you. What do you know about it? (literally, ‘What makes you know?’ After this one understands some such words as, ‘that lack of illness is a mark of honour.’) Would that God had afflicted him with illness, and it had atoned for his evil deeds!” Malik transmitted it in mursal form.

Shaddad b. Aus and as-Sunabihi told how, when they went to visit an invalid, they said to him, “How are you this morning?” He replied, “I am quite comfortable this morning.” Shaddad told him to rejoice that his evil deeds had been atoned for and his sins remitted, for he had heard God’s messenger declare that God who is great and glorious says, “When I afflict a servant of mine who is a believer and he praises me for the affliction I have brought upon him, he will rise from that couch of his as sinless as he was the day his mother gave birth to him.” The Lord who is blessed and exalted will say, “I fettered and afflicted my servant, so record for him what you were recording for him when he was well.” Ahmad transmitted it.
