مُوَطَّأُ مَالِكٍ
Muwatta Malik 1635
The Decree
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّهُ كَانَ يُقَالُ إِنَّ أَحَدًا لَنْ يَمُوتَ حَتَّى يَسْتَكْمِلَ رِزْقَهُ فَأَجْمِلُوا فِي الطَّلَبِ .
Yahya related to me from Malik that he heard that this was said "No one will die until his provision is completed for him, so behave correctly in your seeking it."
