This is narrated from the Messenger of Allah (pbuh) and it is as follows:

Praised One, Glorified, Lord of the angels and the Spirit, Praised One, Glorified, Lord of the angels and the Throne, Praised One, Glorified, Lord of the heavens and the earth, Praised One, Glorified, Lord of the oceans and the mountains; Praised One, Glorified, praised by the fish in the oceans, by the reptiles and the beasts and the hills; Praised One, Glorified, praised by the angels and those who are near to Him; Praised One, Glorified, ??alted, Vanquished everything and created everything in a measure. Praised, Praised, Praised, Praised, Praised, Praised, Praised! Glorified, Glorified, Glorified, Glorified, Glorified, Glorified, Glorified! I pray You to send blessings unto Muhammad (pbuh) and the progeny of Muhammad (pbuh) and to forgive me and have mercy on me, for You are the One, the Unique.

Then you ought to add the following:

Lord! I pray You to make my share of every goodness You have sent down this night, or are sending down this night to be the most generous, of light whereby You guide, or mercy You spread out, or sustenance You divide, or a tribulation You shun, or an evil you expose, and to write for me what you write for Your righteous servants who deserve Your rewards and who deserved security by pleasing You. You affect retribution. You give without a measure; You are the Generous One! I pray You to send blessings unto Muhammad (pbuh) and the progeny of Muhammad (pbuh) and to deal with me mercifully; You are the most Merciful of those who are merciful unto others.

Then you should say:

I pray You like one who is poor and helpless, and I invoke You like one who is poor and humble, and I ask you like one who has submitted willingly to You and admitted his wrong-doing and whose eyes have over-flown with tears, who is most helpless, who has no other means, to grant me this night forgiveness for a,2 my past sins, and to protect me from sinning for the rest of my life, to grant me pilgrimage and umra this year, to make it pilgrimage purely for the sake of achieving Your pleasure, and to enable me to al- ways do so, and do not hinder me from visiting Your House and the grave-site of Your Messenger Muhammad Your blessings and peace be upon him and his progeny. And I plead You, Lord, not to let me remain in dire need of Your creatures, of the jinns and of mankind, of the Arabs and of the non-Arabs, of every being whom You can overpower; for You are on the right path. Lord! Grant me, Lord, of whatever You decide and decree of every destined matter on this night, the fate which cannot be avoided nor can it be altered, to visit Your sacred House among other pilgrims this year whose pilgrimage You appreciate and whose endeavor is forgiven and so are their sins, and to prolong my life-span, to increase my sustenance, and to grant me a dutiful, son, for You can do whatever You will, and You are aware of everything.
