"Allah, the Exalted, said: 'My reward shall be nothing less than Paradise for My faithful servant who, if I take the life of his beloved one from the inhabitants of the world, he bears it patiently in expectation of My reward."[Al-Bukhari]
عن أبي هريرة -- مرفوعًا: «يقول الله -تعالى-: ما لِعَبدِي المُؤمن عِندِي جَزَاء إِذَا قَبَضتُ صَفِيَّه مِنْ أَهلِ الدُّنيَا ثُمَّ احْتَسَبَه إِلاَّ الجنَّة». (البخاري)
