The Prophet of Allah, sallallaahu ‘alayhi wa sallam, clarified the reward of the calamity and expecting the reward for it

“Allah’s Prophet, sallallaahu ‘alayhi wa sallam, was sitting with some of his companions and there was a man with a small son of his, who came from behind his father, and so the man took the boy and sat him before him. The Prophet of Allah, sallallaahu ‘alayhi wa sallam, said to the man: ‘Do you love him?’ The man said: ‘O Messenger of Allah, may Allah The Almighty love you as much as I love him.’ The boy then died, the man abstained from attending gatherings, remembering his son and being sad over him. So the Prophet of Allah, sallallaahu ‘alayhi wa sallam, noticed his absence, and said: ‘Why do I not see so-and-so?’ They said: ‘O Messenger of Allah, his son whom you saw has passed away.’ The Prophet of Allah, sallallaahu ‘alayhi wa sallam, met the man and asked him about his son, and he was informed that he had passed away, so the Prophet of Allah, sallallaahu ‘alayhi wa sallam, consoled the man, then said: ‘O so-and-so, what is more beloved to you, to live your whole life enjoying him, or that in the Hereafter, there is not a door of Paradise that you approach except that you find that he has preceded you there, and is opening the door for you?’  The man said: ‘O Allah, rather, it is more beloved to me that he precedes me to the doors of Paradise, and opens them for me.’ The Prophet of Allah, sallallaahu ‘alayhi wa sallam, said to him: ‘Then that will be for you.’ A man said: ‘O Messenger of Allah, for him alone, or for all of us?’ The Prophet of Allah, sallallaahu ‘alayhi wa sallam, said: ‘No, rather for all of you.’”

“Allah Says: ‘If My slave is stricken with the death of a very close loved one and then (perseveres) hoping for the reward, there is no reward with Me (for him) except Paradise.”

“The term “Then (perseveres) hoping for the reward,” means that the individual is patient with their loss, and hope for the reward with Allah for that; it means to seek the reward from Allah with sincerity.”

` “The Messenger of Allah, sallallaahu ‘alayhi wa sallam, said: ‘Allah is not satisfied with any thing lesser than Paradise as a reward for the one who has been afflicted with the loss of their loved one on earth, then is patient and seeks the reward from Allah.’”

“By Him in Whose hand is my soul, a woman who has a miscarriage will be dragged by the fetus by its umbilical cord to Paradise, so long as she seeks reward for it [by patiently persevering the affliction].”

“When I am afflicted with a trial, I thank Allah for it four times. I thank Him that it was not greater than it was; I thank Him if He grants me patience in dealing with it; I thank Him if He enables me to say, ‘To Allah we belong, and to Him we shall return,’ in hope of the great reward it has; and I thank Him for not making that calamity in my religion.”
