What one should say after the Subh and Maghrib prayers

Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever, after performing the morning prayer, recites this ten times: 'La ilaha illallahu wahdahu la sharika lah, lahu al-mulku wa lahu al-hamdu, wa huwa 'ala kulli shay'in qadir'
(There is no god except Allah Almighty, He alone is the only one worthy of worship, He has no partner; the dominion belongs to Him alone, and praise belongs to Him alone, and He has power over all things),
(the Prophet (peace and blessings be upon him) says:) then this deed will be equal for him to freeing four slaves; because of these words ten good deeds will be recorded for him, and because of these words ten of his sins will be erased, and these words will become a means of protection for him from Satan until the evening; and if a person recites them after Maghrib, he will receive the like of it (that is, the same reward)."
Ahmad recorded it, and al-Tabarani recorded it in abridged form; Ahmad's chain contains Muhammad bin Ishaq, and he is a mudallis, while al-Tabarani's narration contains Muhammad bin Abi Layla, who is thiqah (trustworthy) but suffers from poor memory; the narrators of both are thiqat (trustworthy).

Sayyiduna Abdul Rahman bin Ghanm (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "Whoever, after the Maghrib and Fajr prayers, before getting up and before changing the position of his leg, recites these words ten times: 'La ilaha illallahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, biyadihil-khayr, yuhyi wa yumitu, wa huwa 'ala kulli shay'in qadir'
(There is no deity except Allah Almighty; He alone is the deity, He has no partner; to Him alone belongs the dominion and to Him alone belongs all praise; all good is in His hand; He gives life and He gives death, and He has power over all things)
(the Prophet, peace and blessings be upon him, says:) then for each one of them ten good deeds are recorded for that person, ten of his sins are erased, and he is raised ten degrees; these words become for him a protection from every disliked thing and a protection from the accursed Satan; it is not permissible for any sin to reach that person except shirk (associating partners with Allah); and such a person is the most excellent of people in deeds, except for the one who recited these words more times than he recited them."
Ahmad recorded it, and its narrators are the narrators of the Sahih, except for Shahr bin Hawshab, and his narration is hasan (good).

Sayyidah Umm Salamah (may Allah be pleased with her) narrates: Fatimah came to the Prophet (peace and blessings be upon him) and complained to him about the household work. She said: "O Messenger of Allah, my hands have become blistered from grinding the hand-mill; at one time I grind flour and at another time I knead it." The Prophet (peace and blessings be upon him) said: "If Allah Almighty has destined something for you, it will come to you; but I will guide you to something better than that. When you go to your bed, recite 'Subhan Allah' (glory be to Allah) 33 times, 'Allahu akbar' (Allah is the Greatest) 33 times and 'Alhamdulillah' (all praise is for Allah) 34 times. That makes 100, and this is better for you than getting a servant. And when you have offered the Fajr prayer, recite:
(There is no deity except Allah Almighty; He alone is the deity, He has no partner; to Him alone belongs the dominion, to Him alone belongs all praise; He gives life and He gives death; all good is in His hand, and He has power over all things.)"
The Prophet (peace and blessings be upon him) said: "Recite these words ten times after the Fajr prayer and ten times after the Maghrib prayer, for in return for each one of them ten good deeds are recorded and ten sins are erased, and each one of these phrases is like freeing a slave from the descendants of Sayyiduna Isma'il (peace be upon him). It is not permissible for any sin to reach that person on that day, except shirk. These words, 'La ilaha illallahu wahdahu la sharika lahu' (there is no deity except Allah alone, He has no partner), will be your guard against every devil and every evil, from the time you recite them in the morning until the time you recite them in the evening."
Ahmad recorded it, and al-Tabarani recorded something similar to it that is shorter than this, and he recorded these words: "They will protect you." The chains of both of them are hasan (good).

Sayyiduna Abu al-Darda' (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever, after offering the Fajr prayer and before speaking with anyone, recites these words while his leg is still folded: 'La ilaha illallahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, yuhyi wa yumitu, biyadihil-khayru wa huwa 'ala kulli shay'in qadir'
(There is no deity except Allah Almighty; He alone is the deity, He has no partner; to Him alone belongs the dominion and to Him alone belongs all praise; He gives life and He gives death; all good is in His hand, and He has power over all things)
The Prophet (peace and blessings be upon him) says: whoever recites them ten times, in return for each time ten good deeds will be recorded for him, ten of his sins will be erased, and he will be raised ten degrees; on that day these words will become for him a protection from every kind of disliked thing and a guard against the accursed Satan; for each time, that person will receive the reward of freeing a slave from the descendants of Sayyiduna Isma'il (peace be upon him) worth 12,000; and on that day no sin will attach to that person, except associating partners with Allah Almighty."
(The Prophet, peace and blessings be upon him, says:) "And whoever recites them after the Maghrib prayer will also have the like of that (that is, the same reward)."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; its chain contains Musa bin Muhammad bin Ata' al-Balqawi, who is matruk (abandoned).

Sayyiduna Abu Umamah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: Whoever recites these words after the Fajr prayer: 'La ilaha illallahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, yuhyi wa yumitu, biyadihil-khayr, wa huwa 'ala kulli shay'in qadir'
(There is no deity except Allah Almighty; He alone is the deity, He has no partner; to Him alone belongs the dominion and to Him alone belongs all praise; He gives life and He gives death; all good is in His hand, and He has power over all things)
whoever recites them one hundred times before changing the position of his legs will be, on that day, the most excellent of the people of the earth in deeds, except for the one who recited as much as he did or more than he did."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat, and the narrators of al-Mu'jam al-Awsat are thiqat (trustworthy).

Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever, after finishing the Fajr prayer, recites: 'La ilaha illallahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, biyadihil-khayr, wa huwa 'ala kulli shay'in qadir' (There is no deity except Allah Almighty; He alone is the deity, He has no partner; to Him alone belongs the dominion, to Him alone belongs all praise; all good is in His hand, and He has power over all things) - whoever recites these words ten times will be given seven things in return for them: through them he will receive ten good deeds; through them ten of his sins will be erased; through them he will be raised ten degrees; these words will be for him equal to freeing 10 slaves; these words will be for him a means of protection from Satan and a safeguard from what is disliked; and on that day no sin at all will attach to that person, except associating partners with Allah Almighty. And whoever recites these words after finishing the Maghrib prayer will be given the like of that reward for that night."
Al-Tabarani recorded it via Asim bin Mansur; I did not find anyone who declared him trustworthy or anyone who declared him weak. The remaining narrators of this narration are thiqat (trustworthy).

Sayyiduna Zumayl al-Juhani (may Allah be pleased with him) narrates: When the Prophet (peace and blessings be upon him) had offered the Fajr prayer, he would recite this while his leg was still folded:
'Subhan Allahi wa bihamdihi, wa astaghfirullaha innahu kana tawwaba'
(Allah is free of every imperfection and to Him alone belongs all praise; and I seek forgiveness from Allah Almighty; indeed, He is ever accepting of repentance.)
The Prophet (peace and blessings be upon him) would recite these words seventy times, then he would say: "These seventy phrases become 700, and there is no good for a person whose sins in a single day are more than 700." Then after that the Prophet (peace and blessings be upon him) would turn his face towards the people.
(Allamah al-Haythami says:) I say: After this he mentioned the full narration, which has already passed earlier in the book on the interpretation of dreams.

Sayyidah Asma' bint Wathilah bin al-Asqa' (may Allah be pleased with her) narrates: When my father had offered the Fajr prayer, he would remain seated facing the qiblah and would not speak until the sun rose. Sometimes I would address him regarding some task, but he would not speak with me. I asked: "What is the reason for this?" He said: I heard the Prophet (peace and blessings be upon him) say: "Whoever, after offering the Fajr prayer and before speaking with anyone, recites Surah al-Ikhlas 100 times, then every time he recites Surah al-Ikhlas once, his sins of one year are forgiven."
Al-Tabarani recorded it; its chain contains Muhammad bin Abdul Rahman al-Qushayri, who is matruk (abandoned).
