Al-Adab Al-Mufrad, Book 50, Hadith 1216 (In-Book) ⓘ

'Abdullah ibn 'Amr reported that the Prophet, may Allah bless him and grant him peace, said, "If a Muslim man persists in two actions, he will enter the Garden. They are easy, but those who do them are few.' He was asked, 'What are they, may Allah bless him and grant him peace?' He said, 'That you say "Allahu akbar" ten times, "al-hamdu lillah" ten times, and "Subhana'llah" ten times after every prayer. That is 150 on the tongue and 1500 in the balance.' I saw the Prophet, may Allah bless him and grant him peace, counting them with his hand. Then he said, 'When you go to bed, you should say, "Subhana'llah", "al-hamdu lillah", and "Allahu akbar". That is 100 on the tongue and 1000 in the balance. Who among you can do 2500 bad actions morning and night?' He was asked, 'Messenger of Allah, how is it that they are not counted?' He said, 'Shaytan comes to one of you while he is praying and reminds him of something he has to do such-and-such and such-and-such, so he does not remember to do it.'"

حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ‏:‏ حَدَّثَنَا سُفْيَانُ، عَنْ عَطَاءٍ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللهِ بْنِ عَمْرٍو، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ‏:‏ خَلَّتَانِ لاَ يُحْصِيهِمَا رَجُلٌ مُسْلِمٌ إِلاَّ دَخَلَ الْجَنَّةَ، وَهُمَا يَسِيرٌ، وَمَنْ يَعْمَلُ بِهِمَا قَلِيلٌ، قِيلَ‏:‏ وَمَا هُمَا يَا رَسُولَ اللهِ‏؟‏ قَالَ‏:‏ يُكَبِّرُ أَحَدُكُمْ فِي دُبُرِ كُلِّ صَلاَةٍ عَشْرًا، وَيَحْمَدُ عَشْرًا، وَيُسَبِّحُ عَشْرًا، فَذَلِكَ خَمْسُونَ وَمِئَةٌ عَلَى اللِّسَانِ، وَأَلْفٌ وَخَمْسُمِئَةٍ فِي الْمِيزَانِ، فَرَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يَعُدُّهُنَّ بِيَدِهِ‏.‏ وَإِذَا أَوَى إِلَى فِرَاشِهِ سَبَّحَهُ وَحَمِدَهُ وَكَبَّرَهُ، فَتِلْكَ مِئَةٌ عَلَى اللِّسَانِ، وَأَلْفٌ فِي الْمِيزَانِ، فَأَيُّكُمْ يَعْمَلُ فِي الْيَوْمِ وَاللَّيْلَةِ أَلْفَيْنِ وَخَمْسَمِئَةِ سَيِّئَةٍ‏؟‏ قِيلَ‏:‏ يَا رَسُولَ اللهِ، كَيْفَ لاَ يُحْصِيهِمَا‏؟‏ قَالَ‏:‏ يَأْتِي أَحَدَكُمُ الشَّيْطَانُ فِي صَلاَتِهِ، فَيُذَكِّرُهُ حَاجَةَ كَذَا وَكَذَا، فَلا يَذْكُرُهُ‏.‏
