The Messenger of Allah ﷺ said, "There are two practices which no Muslim man keeps count of without entering Paradise. They are easy, but few are those who act upon them."The Messenger of Allah ﷺ said, "After each of the five prayers, glorify Allah ten times, praise Him ten times, and magnify Him ten times. That is one hundred and fifty on the tongue, but one thousand five hundred on the scale. And when one of you retires to his bed, glorify Allah thirty-three times, praise Him thirty-three times, and magnify Him thirty-four times. That is one hundred on the tongue, but one thousand on the scale."I saw the Messenger of Allah ﷺ counting them on his hand.The Messenger of Allah ﷺ said, "Which of you commits two thousand five hundred sins in a day and a night?"Someone asked, "Messenger of Allah, how is it that we fail to keep count of them?"He replied, "Satan comes to one of you while he is in his prayer and says, 'Remember this, remember that,' and he comes to him at his bedtime and puts him to sleep."
أخبرنا يحيى بن حبيب بن عربي قال حدثنا حماد عن عطاء بن السائب عن أبيه
قال رسول الله ﷺ خلتان لا يحصيهما رجل مسلم إلا دخل الجنة وهما يسير ومن يعمل بهما قليل قال قال رسول الله ﷺ الصلوات الخمس يسبح أحدكم في دبر كل صلاة عشرا ويحمد عشرا ويكبر عشرا فهي خمسون ومائة في اللسان وألف وخمس مائة في الميزان وأنا رأيت رسول الله ﷺ يعقدهن بيده وإذا أوى أحدكم إلى فراشه أو مضجعه سبح ثلاثا وثلاثين وحمد ثلاثا وثلاثين وكبر أربعا وثلاثين فهي مائة على اللسان وألف في الميزان قال قال رسول الله ﷺ فأيكم يعمل في كل يوم وليلة ألفين وخمس مائة سيئة قيل يا رسول الله وكيف لا نحصيهما فقال إن الشيطان يأتي أحدكم وهو في صلاته فيقول اذكر كذا اذكر كذا ويأتيه عند منامه فينيمه
Its isnad is hasan. Abu Dawud narrated it in the Book of Manners, chapter on glorifying Allah before sleep, no. 5065, Tirmidhi, no. 3410, and Ibn Majah, no. 926, from the hadith of Ata bin Saaib in this manner, and Ibn Hibban declared it sahih, no. 2343, and it is found in Al-Kubra, no. 1271.Hammad is Ibn Zayd, and he heard from Ata bin Saaib before his confusion set in.
