Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: There are two qualities; whoever guards them, they will admit him to Paradise. They are easy, but those who act upon them are few. The people asked: O Messenger of Allah! What are those two? He (peace and blessings be upon him) said: After every obligatory prayer, say ten times: Alhamdulillah, Allahu Akbar, and SubhanAllah. Then, when you come to your bed, say one hundred times: SubhanAllah, Allahu Akbar, and Alhamdulillah. These will be two hundred and fifty words on the tongue, but on the scale, they will be two thousand five hundred. (Now tell me) who among you commits two thousand five hundred sins in a day and night? The companions said: Then why are those who act upon them few? He (peace and blessings be upon him) said: Satan comes to you during prayer and starts reminding you of your needs, so he (stands up immediately after the salam and) is unable to say these words. Similarly, he comes (at night) at the time of sleep and makes him sleep before he can say this remembrance, so he is unable to say these words. The narrator says: I saw that the Messenger of Allah (peace and blessings be upon him) used to count them with his hand.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he and Sayyidah Fatimah (may Allah be pleased with her) came to the Noble Prophet (peace and blessings be upon him) to ask for a servant from among the captives, so that the servant could do some of the work and thus lighten their burden a little. But the Prophet (peace and blessings be upon him) refused to give them a servant, … the whole story is mentioned … . Then the Noble Prophet (peace and blessings be upon him) said to both of them: Shall I not inform you of something better than what you have asked for? They said: Yes, indeed. The Prophet (peace and blessings be upon him) said: There are some words which Jibreel (peace be upon him) taught me. Then the Prophet (peace and blessings be upon him) said: After every prayer, say Subhan Allah ten times, Alhamdulillah ten times, and Allahu Akbar ten times. Then when you go to your bed, say Subhan Allah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-four times. Sayyiduna Ali (may Allah be pleased with him) said: By Allah, since the Messenger of Allah (peace and blessings be upon him) taught me these words, I have never abandoned them. Ibn Kawa said: Not even on the night of Siffin? He said: O people of Iraq! May Allah destroy you, yes, yes, not even on the night of Siffin did I abandon them.

Abu Umar Sini says: When a guest would come to Sayyiduna Abu Darda’ (may Allah be pleased with him), he would say to him: Will you stay so that we may let your mount graze in the pasture, or will you go so that we may feed it here? When the guest would say that he was about to leave, Sayyiduna Abu Darda’ (may Allah be pleased with him) would say to him: I do not find anything better for you than what the Messenger of Allah (peace and blessings be upon him) commanded us. The matter is that we said: O Messenger of Allah! All the reward is being taken by the wealthy; they perform Hajj and we cannot perform Hajj, they perform Jihad and we cannot perform Jihad, and they do such and such deeds as well. The Messenger of Allah (peace and blessings be upon him) said: Shall I not guide you to something such that if you hold fast to it, you will perform such a superior deed that none among them does such a deed? After every prayer, say thirty-four times "Allahu Akbar," thirty-three times "Subhan Allah," and thirty-three times "Alhamdulillah."

(Second chain of narration) A man came as a guest to Sayyiduna Abu Darda’ (may Allah be pleased with him). He asked him:“Will you stay so that we may take the mount to the pasture, or will you leave so that we may feed it here?”He replied:“I am going to leave.”Upon hearing this, he said:“Then I will give you provision for the journey, and it is such a provision that if there were anything better than it, I would have given you that. (The details are as follows:) I came to the Messenger of Allah (peace and blessings be upon him) and said: ‘O Messenger of Allah! The wealthy people are taking away (all the rewards) of this world and the Hereafter. We pray, and they also pray; we fast, and they also fast; but they give charity and we do not give charity.’ The Prophet (peace and blessings be upon him) said: ‘Shall I not guide you to something such that if you act upon it, those before you will not surpass you, and those after you will not reach your rank, except those who do as you do? After every prayer, say thirty-three times Subhan Allah, thirty-three times Alhamdulillah, and thirty-four times Allahu Akbar.’

Mawla of the Messenger, Sayyiduna Thawban (may Allah be pleased with him) narrates that when the Messenger of Allah (peace and blessings be upon him) would finish his prayer with salam, he would seek forgiveness three times and then recite this supplication: "Allahumma anta as-salamu wa minka as-salam, tabarakta ya dhal-jalali wal-ikram." (O Allah! You are Peace and from You is peace. You are blessed, O Possessor of Majesty and Honor.)

It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) used to recite this supplication after every prayer: "O Allah! I seek refuge with You from disbelief, poverty, and the torment of the grave." (O Allah! I seek Your protection from disbelief, poverty, and the punishment of the grave.)

(Muslim bin Abi Bakrah says:) I passed by my father and he was making this supplication: "O Allah! I seek refuge with You from disbelief, poverty, and the punishment of the grave." So I also memorized this supplication from him and began to recite it after every prayer. Once, my father passed by me while I was making this supplication, and he asked me: "My child! Where did you learn these words from?" I said: "Father! I heard you reciting them after every prayer, so I learned these words from you." He said: "Dear son! Hold fast to them, for the Messenger of Allah (peace and blessings be upon him) used to recite them after every prayer."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) used to recite this supplication at the end of Witr: "O Allah! Indeed, I seek refuge in Your pleasure from Your displeasure, and I seek refuge in Your pardon from Your punishment, and I seek refuge in You from You. I cannot enumerate praise of You; You are as You have praised Yourself." (O Allah! Indeed, I seek refuge in Your pleasure from Your displeasure, I seek refuge in Your pardon from Your punishment, and I seek refuge in You from You. I cannot enumerate praise of You; You are as You have praised Yourself.)

It is narrated from the scribe of Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him), Warrad, that Sayyiduna Mughirah (may Allah be pleased with him) wrote to Sayyiduna Mu’awiyah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) would finish the prayer with salam, he used to say: "There is no god but Allah, He is alone, He has no partner, to Him belongs the dominion and to Him belongs all praise, and He is over all things Powerful. O Allah! None can withhold what You give, and none can give what You withhold, and the wealth of the wealthy cannot benefit them against You."

(Second chain) Sayyiduna Muawiyah (may Allah be pleased with him) wrote to Sayyiduna Mughirah (may Allah be pleased with him) asking him to write to him something he had heard from the Messenger of Allah (peace and blessings be upon him). He said: When the Prophet (peace and blessings be upon him) finished the prayer, he would say: La ilaha illallah... ... . He mentioned it as in the first hadith.
