حَدَّثَنَا أَبُو مُعَاوِيَةَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ الْوَلِيدِ الْوَصَّافِيُّ عَنْ عَطِيَّةَ الْعَوْفِيِّ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ قَالَ حِينَ يَأْوِي إِلَى فِرَاشِهِ أَسْتَغْفِرُ اللَّهَ الَّذِي لَا إِلَهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ وَأَتُوبُ إِلَيْهِ ثَلَاثَ مَرَّاتٍ غَفَرَ اللَّهُ لَهُ ذُنُوبَهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ وَإِنْ كَانَتْ مِثْلَ رَمْلٍ عَالِجٍ وَإِنْ كَانَتْ مِثْلَ عَدَدِ وَرَقِ الشَّجَرِ

Narrated to us [Abu Mu'awiyah] said: Narrated to us [Ubaidullah Ibnul Walid Al Washshafi] from ['Athiyyah Al 'Aufi] from [Abu Sa'id Al Khudri] said: The Messenger of Allah peace and blessings be upon him said: "Whoever when going to sleep says: ASTAGHFIRULLAH ALLADZII LAA ILAAHA ILLA HUWAL HAYYUL QAYYUUMU WA ATUUBU ILAIHI (I ask forgiveness from Allah that there is no god worthy of worship except Him, the Almighty and the Most True, and I re to Him) three times, then Allah will forgive his sins even though it is like the foam on the sea, even though it is like a mountain of sand, even though it is like the number of leaves on a tree.
