The Prophet (S) said to Abu Bakr: "I passed by you while you were reciting and your voice was low." He said: "I let He who, I was consulting hear." He said: "Raise your voice." Then he said to Umar: "I passed by while you were reciting and your voice was loud." So he said: "I repel drowsiness and keep Ash-Shaitan away." So he said: "Lower your voice."
Jami` at-Tirmidhi Book 2, Hadith 300
← Previous Hadith Allah's Messenger (S) said: "Allah, Blessed and Exalted is He, descends to the earth's heaven every night when the first third of the night has passed. He says: "I am the Sovereign. Is there any who calls upon Me so that I may respond to him? Is there any who asks of Me that I may give him? Is there any who seeks forgiveness from Me so that I may forgive him?' He continues in that until the illumination of Al-Fajr."
