It was narrated that Qais bin 'Ubad said:

"Ammar bin Yasir led the people in prayer and he made the prayer short. It was as if they disliked that, so he said: 'Did I not do bowing and prostration properly?' They said: 'Yes.' He said: 'And I said a supplication that the Prophet ﷺ used to say:Allahumma bi 'ilmikal-ghaiba wa qudratika 'alal-khalqi ahini ma 'alimtal-hayata khairan li, wa tawaffani idha 'alimtal-wafata khairan li. Allahumma as'aluka khashyataka fil-ghaibi wash-shahadati wa as'aluka kalimatul-aqua fir-rida'i wal ghadab, wa as'alukal-qasda fil faqr wal-ghina, wa as'aluka na'iman la yanfadu wa as'aluka qurrata ainan la tanqati'u wa as'alukar-rida'i ba'dal-qada'i wa as'aluka bardal 'aishi ba'dal-mawti, wa as'aluka ladhatan-nazari ila wajhika wash-shawqa ila liqa'ika fi fitnatin mudillatin, Allahumma zayyina dizinatil-imani waj'alna hudatan muhtadin (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."
