Sahih Bukhari Volume 1, Book 10, Hadith 845

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، عَنْ وَرَّادٍ، كَاتِبِ الْمُغِيرَةِ بْنِ شُعْبَةَ قَالَ أَمْلَى عَلَىَّ الْمُغِيرَةُ بْنُ شُعْبَةَ فِي كِتَابٍ إِلَى مُعَاوِيَةَ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَقُولُ فِي دُبُرِ كُلِّ صَلاَةٍ مَكْتُوبَةٍ ‏"‏ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ، لَهُ الْمُلْكُ، وَلَهُ الْحَمْدُ، وَهْوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ، اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ، وَلاَ مُعْطِيَ لِمَا مَنَعْتَ، وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ ‏"‏‏.‏ وَقَالَ شُعْبَةُ عَنْ عَبْدِ الْمَلِكِ بِهَذَا، وَعَنِ الْحَكَمِ عَنِ الْقَاسِمِ بْنِ مُخَيْمِرَةَ عَنْ وَرَّادٍ بِهَذَا‏.‏ وَقَالَ الْحَسَنُ الْجَدُّ غِنًى‏.

Narrated By Warrad : (The clerk of Al-Mughira bin Shu'ba) Once Al-Mughira dictated to me in a letter addressed to Mu'awiya that the Prophet used to say after every compulsory prayer, "La ilaha ilallah wahdahu la sharika lahu, lahul-mulku wa-lahul-hamdu, wahuwa ala kulli shai in qadir. Allahumma la mani 'a lima a'taita, wa la mu'tiya lima mana'ta, wa la yanfa'u dhal-jaddi minka-l-jadd. (None has the right to be worshipped but Allah and He has no partner in Lordship or in worship or in the Names and the Qualities, and for Him is the Kingdom and all the praises are for Him and He is omnipotent. O Allah! Nobody can hold back what you give and nobody can give what You hold back. Hard (efforts by anyone for anything cannot benefit one against Your Will)." And Al-Hasan said, "Al-jadd' means prosperity."
