The Death of One's Child...

Narrated from Abu Moosa al-Ash’ari (may Allaah be pleased with him), that the Messenger of Allaah (peace and blessings of Allaah be upon him) said:

“When the child of a person dies, Allaah says to His angels: ‘You have taken the soul of the child of My slave?’ They say: ‘Yes.’ He says: ‘You have taken the apple of his eye?’ They say: ‘Yes.’ He says: ‘What did My slave say?’ They say: ‘He praised You and said innaa Lillaahi wa innaa ilayhi raaji’oon.’ And Allaah says: ‘Build for My slave a house in Paradise, and call it the house of praise.’”

Narrated by al-Tirmidhi, 1021; classed as hasan by al-Albaani in Saheeh al-Tirmidhi

The death of one of one's children is a screen against the Fire.
