Imam Malik, may Allah have mercy on him, said: No person should recite a verse of prostration after the Asr prayer or after Fajr, because the Messenger of Allah, peace and blessings be upon him, forbade prayer after the morning prayer until the sun rises, and forbade prayer after Asr until the sun sets. And the prostration of recitation is like prayer, so no person should recite a verse of prostration during these two times.

Imam Malik, may Allah have mercy on him, was asked: If a person recites a verse of prostration and a menstruating woman hears it, should that woman also perform the prostration? Imam Malik, may Allah have mercy on him, replied: No, for both a man or a woman, the prostration is only valid when both are in a state of ablution.

Imam Malik, may Allah have mercy on him, was asked: If a woman recites a verse of prostration and a man hears her, should that man also perform prostration along with the woman? He replied: No, rather prostration becomes obligatory on the listener only when he is a follower (muqtadi) of the one who is reciting the verse of prostration. And it is not the case that whoever hears the verse of prostration from someone and is not a follower of the reciter should perform prostration.

It is narrated from Sayyiduna Abu Sa'id Khudri, may Allah be pleased with him, that he said: I heard a man reciting «﴿قُلْ هُوَ اللَّهُ أَحَدٌ﴾» repeatedly, so when morning came, I went to the Messenger of Allah, peace and blessings be upon him, and mentioned this matter to him. And Sayyiduna Abu Sa'id, may Allah be pleased with him, considered this surah to be of little significance in his own understanding. Then the Messenger of Allah, peace and blessings be upon him, said: "By Him in Whose hand is my soul, this surah is equal to one third of the Qur'an."

It is narrated from Sayyiduna Abu Huraira (may Allah be pleased with him), he used to say: I came with the Messenger of Allah (peace and blessings be upon him), and he heard a man reciting «﴿قُلْ هُوَ اللّٰهُ أَحَدٌ﴾» . He said: "It has become obligatory." I asked: "What has?" He said: "Paradise." Sayyiduna Abu Huraira (may Allah be pleased with him) said: I wanted to go and give this man the glad tidings, but I feared that my morning meal with the Messenger of Allah (peace and blessings be upon him) would be lost, so I ate first, then I went, but I saw that the man had gone.

Humaid bin Abdur Rahman bin Awf said that «﴿قُلْ هُوَ اللّٰهُ أَحَدٌ﴾» is equal to one third of the Qur'an and «﴿تَبَارَكَ الَّذِي بِيَدِهِ الْمُلْكُ﴾» will argue on behalf of its reciter.

It is narrated from Sayyiduna Abu Huraira, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever says «لَا إِلَهَ إِلَّا اللّٰهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ» one hundred times in a day, it is as if he has freed ten slaves, and one hundred good deeds will be written for him, and one hundred sins will be erased from him, and he will be protected from the evil of Satan for the whole day until evening, and no one will bring a better deed than this except the one who does more than this."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever says: «سُبْحَانَ اللّٰهِ وَبِحَمْدِهِ» one hundred times in a day, his sins will be erased even if they are like the foam of the sea."

Sayyiduna Abu Huraira (may Allah be pleased with him) said: Whoever says «سُبْحَانَ اللّٰهِ» thirty-three times after every prayer, and says «اَللّٰهُ أَكْبَر» thirty-three times, and says «اَلْحَمْدُ لِلّٰهِ» thirty-three times, and completes one hundred with «لَا إِلٰهَ إِلَّا اللّٰهُ، وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ» , then his sins will be forgiven even if they are like the foam of the sea.

Saeed bin Musayyib said: The enduring good deeds are these words: «اَللّٰهُ أَكْبَرُ» , «سُبْحَانَ اللّٰهِ» , «اَلْحَمْدُ لِلّٰهِ» , «لَا إِلٰهَ إِلَّا اللّٰهُ» , «لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللّٰهِ» .
