308. Best Masnun Islamic Dua for Death & Patience
إِنَّ لِلَّهِ مَا أَخَذَ وَلَهُ مَا أَعْطَى وَكُلٌّ عِنْدَهُ بِأَجَلٍ مُسَمًّى
اِنَّ لِلّٰهِ مَا اَخَذَ وَلَهُ مَا اَعْطٰى وَكُلٌّ عِنْدَهُ بِاَجَلٍ مُسَمَّى
Inna lillaahi maa 'akhadha, wa lahu maa 'a'taa, wa kullun 'indahu bi'ajalin musamma
Translation
Whatever Allah takes is His, and whatever He gives is His, and everything with Him has a limited fixed term (in this world).
Narrated by Usama bin Zaid (RA): We were with the Prophet (ﷺ) 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 (ﷺ) said (to the messenger), (The dua is Mentioned above). So order her to be patient and hope for Allah's reward.
