Hadith 256

وعن أبي هريرة رضي الله عنه عن رسول الله صلى الله عليه وآله وسلم قال : « من سبح الله دبر كل صلاة ثلاثا وثلاثين وحمد الله ثلاثا وثلاثين وكبر الله ثلاثا وثلاثين فتلك تسع وتسعون وقال تمام المائة : لا إله إلا الله وحده لا شريك له له الملك وله الحمد وهو على كل شيء قدير غفرت خطاياه ولو كانت مثل زبد البحر ». رواه مسلم. وفي رواية أخرى : أن التكبير أربع وثلاثون.
Narrated Abu Hurairah (RA) Allah's Messenger (ﷺ) said: "Whoever glorifies Allah (by saying Subhan-Allah) after every Salat (prayer) thirty-three times, and praises Allah (by saying Alhamdu-lillah) thirty-three times, and exalts Allah (by saying Allahu Akbar) thirty-three times, those are ninety-nine in all, and says to complete a hundred: La ilaha ill-Allahu, wahdahu la sharika lahu, lahul-mulku wa lahulhamdu, wa Huwa 'ala kulli shai'in Qadir (There is nothing which deserves to be worshipped except Allah Alone Who has no partner; to Him belongs the kingdom, to Him praise is due, and He has power over everything), his sins will be forgiven, even if they are as abundant as the foam of the sea." [Reported by Muslim]. In another narration it is mentioned: "at-Takbir (Allah is the Most Great) is thirty-four times."

Takhrij:
«أخرجه مسلم، المساجد، باب استحباب الذكر بعد الصلاة....، حديث:597.»©Explanation:
➊ From this hadith, it is understood that reciting these words at the end of every prayer—whether it is a voluntary (nafl) prayer or an obligatory (fard) prayer—is Sunnah, and there is also the glad tidings of abundant sins being forgiven. Although some scholars have declared the recitation of these words after the obligatory prayers to be legislated (mashru‘).

➋ The background of this supplication, as mentioned in Sahih al-Bukhari and Sahih Muslim, is as follows: One day, the poor among the Muhajirun (radi Allahu anhum) came to the service of the Noble Prophet (sallallahu alayhi wa sallam) and said: “O Messenger of Allah (sallallahu alayhi wa sallam)! The wealthy and affluent people have taken away the highest ranks and everlasting bliss. They pray as we pray and fast as we fast, but they possess abundant wealth with which they perform Hajj and ‘Umrah, strive in jihad, free slaves, and give charity and alms (sadaqah)—we cannot compete with them because we do not have such abundance of wealth.”

The Prophet (sallallahu alayhi wa sallam), comforting them, said: “Shall I not tell you of an action which, if you do it, you will attain the reward of those who have surpassed you, and none after you will overtake you, and you will be the best among those with whom you are, except for one who does the same as you do?” On this occasion, he instructed them to recite the aforementioned words after every prayer.

(Sahih al-Bukhari, Kitab al-Adhan, Chapter: Remembrance after the prayer, Hadith: 843; and Sahih Muslim, Kitab al-Masajid, Chapter: Recommendation of remembrance after the prayer and clarification of its manner, Hadith: 595)

➌ Two methods of reciting these words are understood from this hadith: One is to say “Subhan Allah” thirty-three times, “Alhamdulillah” thirty-three times, and “Allahu Akbar” thirty-four times. The second is to recite all three words thirty-three times each, and then once say “La ilaha illa Allah wahdahu la sharika lahu, lahu’l-mulku wa lahu’l-hamdu wa huwa ‘ala kulli shay’in qadir,” thus completing the count of one hundred.

If the three words are recited in order—thirty-three, thirty-three, and thirty-four times—then “La ilaha illa Allah…etc.” should not be recited, as this is not established from the Sunnah.
