اَللَّهُمَّ بِعِلْمِكَ الْغَيْبَ وَقُدْرَتِكَ عَلَى الْخَلْقِ أَحْيِنِي مَا عَلِمْتَ الْحَيَاةَ خَيْرًا لِيْ، وَتَوَفَّنِيْ إِذَا عَلِمْتَ الْوَفَاةَ خَيْرًا لِي، اَللَّهُمَّ وَأَسْأَلُكَ خَشْيَتَكَ فِي الْغَيْبِ وَالشَّهَادَةِ وَأَسْأَلُكَ كَلِمَةَ الْحَقِّ فِي الرِّضَا وَالْغَضَبِ، وَأَسْأَلُكَ الْقَصْدَ فِي الْفَقْرِ وَالْغِنَى، وَأَسْأَلُكَ نَعِيمًا لَا يَنْفَدُ، وأَسْأَلُكَ قُرَّةَ عَيْنٍ لَا تَنْقَطِعُ، وَأَسْأَلُكَ الرِّضَا بَعْدَ الْقَضَاءِ، وَأَسْأَلُكَ بَرْدَ الْعَيْشِ بَعْدَ الْمَوْتِ، وَأَسْأْلُكَ لَذَّةَ النَّظَرِ إِلَى وَجْهِكَ، وَالشَّوْقَ إِلَى لِقَائِكَ، فِي غَيْرِ ضَرَّاءَ مُضِرَّةٍ، وَلَا فِتْنَةٍ مُضِلَّةٍ، اَللَّهُمَّ زَيِّنَّا بِزِينَةِ الْإِيمَانِ، وَاجْعَلْنَا هُدَاةً مُهْتَدِينَ

Allaahumma bi 'ilmikal-ghaiba wa qudratika 'alal-khalqi a’hyini maa 'alimtal-‘hayaata khairan li, wa tawaffani idhaa 'alimtal-wafata khairan li.

O Allah, by Your knowledge of the unseen and Your power over creation, keep me alive so long as You know that living is good for me and cause me to die when You know that death is better for me. O Allah, cause me to fear You in secret and in public. I ask You to make me true in speech in times of pleasure and of anger. I ask You to make me moderate in times of wealth and poverty. And I ask You for everlasting delight and joy that will never cease. I ask You to make me pleased with that which You have decreed and for an easy life after death. I ask You for the sweetness of looking upon Your face and a longing to meet You in a manner that does not entail a calamity that will bring about harm or a trial that will cause deviation. O Allah, beautify us with the adornment of faith and make us among those who guide and are rightly guided. ‘Ata bin As-Sa'ib (R) narrated that his father said: "Ammar bin Yasir (RA) led us in prayer and he made it brief. Some of the people said to him: 'You made the prayer sort (or brief).' He said: 'Nevertheless I still recited supplications that I heard from the Messenger of Allah (ﷺ).' When he got up and left, a man followed him and asked him about that supplication, then he came and told the people: (The dua is mentioned above)
