In an authentic hadith, the Prophet (bpuh) related that Allah said:
"When I have taken away from someone a most beloved one [to him], and then he [patiently] expects a reward [from Me], I will compensate him with Paradise."
In another authentic hadith, the Prophet related that Allah said:
"Whoever I have tested in his two beloved ones --- meaning his eyes [by taking away his sight] ---- I will compensate him for them with Paradise."
(Verily it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind.) (Qur'an 22: 46)
ln an authentic hadith related by Tirmidhi, the Prophet (Blessings and Peace be upon him) said:
"Verily, when Allah takes away the son of one of His believing slaves, He says to the angels: 'Have you taken the son of my believing slave? They answer, 'Yes. He then says, 'You took (away) the fruit of his heart? They answer, Yes. Allah says, what did My slave say? They answer, He praised you and said: Verily, to Allah do we all belong, and to Him is our return? Allah orders them, Build for My slave a house in Paradise, and call it the house of Praise."'
(Only those who are patient shall receive their rewards in full, without reckoning.) (Qur'an 39: 10)
(Salaamun 'Alaykum [peace be upon you] for that you persevered in patience!) (Qur'an 13: 24)
(Our Lord! Pour forth on us patience.) (Qur'an 2: 250)
(And endure you patiently [O' Muhammad]; your patience is not but from Allah.) (Qur'an 16: 127)
(So be patient [O' Muhammad]. Verily, the Promise of Allah is true.)
(Qur'an 30: 60)
The Prophet (bpuh) said:
"Verily, the greatness of reward is proportionate to the greatness of the test. And indeed, if Allah loves a people, He tests them. Whoever is contented, for him is pleasure, and whoever is angry, upon him is wrath."
Patience, preordainment, and reward from Allah are important issues to be considered when calamity strikes. And we should know that the One Who took away is the One Who gave in the first place.
(Verily! Allah commands that you should render back the trusts to those, to whom they are due.) (Qur'an 4: 58)
A poet said:
"Wealth and family are only loans for a period, And the day must come when a loan is returned."
