Musnad Ahmed: Hadith 2463

The Prophet (ﷺ) embraced a daughter of his who was dying and held her against his chest, then she died as she was leaning against his chest. Umm Aiman screamed and it was said: Are you weeping in the presence of the Messenger of Allah (ﷺ)? She said: Don't I see you weeping, O Messenger of Allah? He said: “I am not weeping; rather it is compassion. The believer is fine in all situations: his soul comes out of his body whilst He is still praising Allah, may He be glorified and exalted.”
