Assalamu'alaykumWhats is the authenticity of below hadeeth Duaa ?It was narrated from ‘Ata’ ibn as-Saa’ib that his father said: ‘Ammaar ibn Yaasir led us in prayer, and he made it brief. Some of the people said to him: You have made the prayer brief. He said: But in it I offered a supplication that I heard from the Messenger of Allah (blessings and peace of Allah be upon him). When he left, one of the people – namely my father – followed him, and asked him about the supplication, then he came and told the people about it: “O Allah, by virtue of Your knowledge of the unseen and Your power over creation, grant me life so long as You know that life is good for me, and cause me to die if You know that death is good for me. O Allah, I ask You to enable me to fear You in private and in public, and I ask You to enable me to speak the truth whether I am calm or angry, and I ask You for moderation in spending whether I am poor or rich. I ask You for blessing that will never end, and I ask You for delight that will never cease, and I ask You for contentment after Your decree comes to pass, and I ask You for a life of bliss after death, and I ask You for the joy of gazing upon Your Countenance, and longing to meet You, with no unbearable harm or misleading turmoils. O Allah, adorn us with the adornment of faith and cause us to be guided and to guide others.Narrated by an-Nasaa’i in al-Mujtaba (no. 1305)JazakAllahukhayran

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

This Hadeeth is Saheeh (sound), and it was reported by Imaam Ahmad, An-Nasaa’i, Ibn Hibbaan and Al-Haakim. Al-Haakim declared it Saheeh and  Ath-Thahabi concurred. Al-Albaani also declared it Saheeh.

Allaah Knows best.
