Narrated Usama: Once while I was with the Prophet and Sa`d, Ubai bin Ka`b and Mu`adh were also sitting with him, there came to him a messenger from one of his daughters, telling him that her child was on the verge of death. The Prophet told the messenger to tell her, "It is for Allah what He takes, and it is for Allah what He gives, and everything has its fixed time (limit). So (she should) be patient and look for Allah's reward."

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 convey 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 Sa`d bin 'Ubada, Mu`adh 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. Sa`d 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 merciful (to others).

Narrated Usama: Once a daughter of Allah's Apostle sent a message to Allah's Apostle while Usama, Sa`d, and my father or Ubai were (sitting there) with him. She said, (in the message); My child is going to die; please come to us." Allah's Apostle returned the messenger and told him to convey his greetings 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): so she should be patient and hope for Allah's reward." Then she again sent for him swearing that he should come; so The Prophet got up, and so did we. When he sat there (at the house of his daughter), the child was brought to him, and he took him into his lap while the child's breath was disturbed in his chest. The eyes of Allah's Apostle started shedding tears. Sa`d said, "What is this, O Allah's Apostle?" The Prophet said, "This is the mercy which Allah has lodged in the hearts of whoever He wants of His slaves, and verily Allah is merciful only to those of His slaves who are merciful (to others).'

Narrated Usama bin Zaid: We were with the Prophet when suddenly there came to him a messenger from one of his daughters who was asking him to come and see her son who was dying. The Prophet said (to the messenger), "Go back and tell her that whatever Allah takes is His, and whatever He gives is His, and everything with Him has a limited fixed term (in this world). So order her to be patient and hope for Allah's reward." But she sent the messenger to the Prophet again, swearing that he should come to her. So the Prophet got up, and so did Sa`d bin 'Ubada and Mu`adh bin Jabal (and went to her). When the child was brought to the Prophet his breath was disturbed in his chest as if it were in a water skin. On that the eyes of the Prophet became flooded with tears, whereupon Sa`d said to him, "O Allah's Apostle! What is this?" The Prophet said, "This is mercy which Allah has put in the heart of His slaves, and Allah bestows His mercy only on those of His slaves who are merciful (to others)."
