Abu Hurairah reported,

The poor companions came to the Prophet ﷺ and said, "The wealthy people have taken the higher ranks and lasting bliss. They pray as we pray, they fast as we fast, yet they have surplus wealth with which they perform Hajj and Umrah, fight in jihad, and give charity."The Messenger of Allah ﷺ said, "Shall I tell you of a practice by which, if you adopt it, you will catch up with those who have surpassed you, and no one after you will catch up with you, and you will be the best of any community among whom you live, except for those who do the same? Glorify Allah, praise Him, and proclaim His greatness thirty-three times after every prayer."We then differed among ourselves. Some of us said, "We should glorify thirty-three times, praise thirty-three times, and proclaim His greatness thirty-four times."So I returned to him, and he said, "You say SubhanAllah, Alhamdulillah, and Allahu Akbar, until each of them reaches thirty-three."

Sahih

عن أبي هريرة

ﷺ قال: جاء الفقراء إلى النبي ﷺ فقالوا: ذهب أهل الدثور من الأموال بالدرجات العلى والنعيم المقيم: يصلون كما نصلي، ويصومون كما نصوم، ولهم فضل من أموال يحجون بها ويعتمرون، ويجاهدون ويتصدقون. قال رسول الله ﷺ: ألا أحدثكم بأمر إن أخذتم به أدركتم من سبقكم، ولم يدرككم أحد بعدكم، وكنتم خير من أنتم بين ظهرانيه، إلا من عمل مثله، تسبحون وتحمدون وتكبرون خلف كل صلاة ثلاثا وثلاثين، فاختلفنا بيننا: فقال بعضنا: نسبح ثلاثا وثلاثين، ونحمد ثلاثا وثلاثين، ونكبر أربعا وثلاثين. فرجعت إليه، فقال: تقول سبحان الله، والحمد لله، والله أكبر، حتى يكون منهن كلهن ثلاث وثلاثون.
