Hujr bin Qays al-Madari (may Allah have mercy on him) said: I spent a night with the Commander of the Believers, Sayyiduna Ali bin Abi Talib (may Allah be pleased with him), and I heard him, while he was performing the night prayer (tahajjud), when he passed by this verse: "Have you considered what you emit? Is it you who create it, or are We the Creator?", say three times: "Rather You, O my Lord! (You are the Creator)." Then he recited: "Have you considered what you sow? Is it you who make it grow, or are We the grower?" and said twice: "Rather You, O my Lord! (You make it grow)." Then, when he recited: "Have you considered the water that you drink? Is it you who brought it down from the clouds, or are We the One who sends it down?", he said three times: "Rather You, O my Lord! (You send it down)." Then, when he recited: "Have you considered the fire that you kindle? Is it you who produced its tree, or are We the Producer?", he said three times: "Rather You, O my Lord! (You are the Producer)." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.
