Salman (ra) schooling a companion with hadiths and ayahs of the Qur’an, ending with an amazing narration about the comparison between Ali (as) and Surat al-Ikhlaas.
Imam Ja’far al-Sadiq (as) quotes his forefathers (as) saying that the Messenger of Allah (sawa) once asked his companions, “Which one of you fasts all the time?” Salman al-Farsi (ra) said, “I do, O Messenger of Allah!”
The Messenger of Allah (sawa) asked them, “Which one of you says prayers the whole of the night?” Salman al-Farsi (ra) “I do, O Messenger of Allah!”
The Messenger of Allah (sawa) asked them, ‘Which one of you recites the entire text of the Qur’an every day?” Salman al-Farsi (ra) for the third time said, “I do, O Messenger of Allah!”
One of the Prophet’s companions became angry and said, “O Messenger of Allah! Salman is a Persian who wants to brag and demonstrate his superiority over us, we men of Quraysh. You asked us, ‘Which one of you fasts the whole time?’ and he said he does so, while he eats most of the time. And you asked us, ‘Which one of you says prayers the entire night?’ and he again said he did so, while he sleeps most of the night. And you asked us, ‘Which one of you recites the entire text of the Qur’an every day?’ and he for the third time said that he did so, while most of the time he is silent.” The Messenger of Allah (sawa) rebuked that man and said, “Keep your silence, so-and-so, for how far you are from Luqman the Wise! Ask him, and he will explain to you,”
The companion turned to Salman and asked him thus: “O father of Abdullah! You have claimed that you fast the whole time, haven’t you?” Salman answered him in the affirmative, so the companion said, “But I have seen you eating most of the time!” Salman said, “It is not what you say! I fast three days in every month, and Allah, the most Exalted, the most Glorified One, says, ‘Whoever does a good deed will be rewarded ten-fold’ (Surat al-An’am, verse 16). And I join the month of Sha’ban with the month of Ramadan in my fast, so it is regarded as though I fast the whole time.”
The man then asked him, “But you claim that you spend your entire night offering prayers, don’t you?” Salman answered in the affirmative, whereupon that man said to him, “How so since most of your night you are in bed?” Salman said, “It is not as you say. I have heard my beloved Messenger of Allah (sawa) say, ‘Whoever remains in a state of tahara (purification) during his sleep will be regarded as though he spent the whole night offering prayers,’ and I do remain tahir!”
The man still asked him, “Have you not claimed that you recite the entire text of the Qur’an every day?” Salman said, “I have.” The man then asked him, “But you spend most of the day silent!” Salman said, “It is not as you say, but I have heard my beloved Messenger of Allah (sawa) telling Ali (as): ‘O father of al-Hassan (as)! Your similitude in my nation is like that of Surat al-Ikhlas: whoever recites it once is considered as having recited one third of the entire text of the Qur’an, and whoever recites it twice is considered as having recited two-thirds of the Qur’an, while whoever recites it thrice will be regarded as having recited the entire text of the Qur’an; whoever loves you with his tongue completes one third of his imaan (conviction), and whoever loves you with both his tongue and heart completes two thirds of his imaan, whereas whoever loves you with his tongue and heart and assists you with his hand (i.e. physically with his might and means) perfects his imaan. I swear by the One Who sent me with the truth, O Ali! Had all people on earth loved you as those in the heavens do, nobody would have been tormented with the Fire,’ and l do recite Surat al-Ikhlaas thrice daily.”
The man then stood up and left as if someone had filled his mouth with a rock (Arab proverb).
