question #3 Sahih al-Bukhari 1284, Book 23, Hadith 44 : What does the hadith teach about the relationship between divine mercy and human compassion?

The daughter of the Prophet (p.b.u.h) sent (a messenger) to the Prophet (ﷺ) requesting him to come as her
child was dying (or was gasping), but the Prophet (ﷺ) 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 (ﷺ) 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 Messenger (ﷺ) 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 Messenger (ﷺ)! 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).
