Sunan Ibn Majah, Hadith 3799 ⓘ

It was narrated from Abu Saeed that : the Prophet said: "Whoever says, following the morning prayer: La ilaha illallahu wahdahu la sahrikalau, lahul mulku wa lahul hamdu, bi yadihil khair, wa huwa ala kulli shay'in qadir (None has the right to be worshipped but Allah alone, with no partner or associate. His is the dominion, all praise is to Him, in His Hand is all goodness, and He is Able to do all things), it will be as if he freed slave from among the sons of Isma'il."

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا بَكْرُ بْنُ عَبْدِ الرَّحْمَنِ، حَدَّثَنَا عِيسَى بْنُ الْمُخْتَارِ، عَنْ مُحَمَّدِ بْنِ أَبِي لَيْلَى، عَنْ عَطِيَّةَ الْعَوْفِيِّ، عَنْ أَبِي سَعِيدٍ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ ‏ "‏ مَنْ قَالَ فِي دُبُرِ صَلاَةِ الْغَدَاةِ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ بِيَدِهِ الْخَيْرُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ - كَانَ كَعَتَاقِ رَقَبَةٍ مِنْ وَلَدِ إِسْمَاعِيلَ ‏" ‏ ‏.‏
