Muwatta Malik, Book 46, Hadith 1635 (In-Book) ⓘ
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."
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّهُ كَانَ يُقَالُ إِنَّ أَحَدًا لَنْ يَمُوتَ حَتَّى يَسْتَكْمِلَ رِزْقَهُ فَأَجْمِلُوا فِي الطَّلَبِ .
