Volume 2, Book 23, Number 373:
Narrated Usama bin Zaid:
The daughter of the Prophet (p.b.u.h) sent (a messenger) to the Prophet requesting him to come as
her child was dying (or was gasping), but the Prophet returned the messenger and told him to con –
vey his greeting to her and say: “Whatever Allah takes is for Him and whatever He gives, is for Him,
and everything with Him has a limited fixed term (in this world) and so she should be patient and
hope for Allah’s reward.” She again sent for him, swearing that he should come. The Prophet got up,
and so did Sad bin ‘Ubada, Muadh bin Jabal, Ubai bin Ka’b, Zaid bin Thabit and some other men. The
child was brought to Allah’s Apostle while his breath was disturbed in his chest (the sub-narrator
thinks that Usama added: ) as if it was a leather water-skin. On that the eyes of the Prophet (p.b.u.h)
started shedding tears. Sad said, “O Allah’s Apostle! What is this?” He replied, “It is mercy which Allah
has lodged in the hearts of His slaves, and Allah is merciful only to those of His slaves who are mer –
ciful (to others).
