Narrated Abu Said Al-Khudri (ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ) : The Prophet ﷺ said to his companions, "Is it difficult 4 any of u to recite one third of the Qur'an in one night?" This suggestion was difficult for them so they said, "Who among us has the power to do so, O Allah's Apostle ﷺ?" Allah Apostle ﷺ replied: " Allah ﺳﺒﺤﺎﻧﻪ ﻭﺗﻌﺎﻟﻰ (the) One, the Self-Sufficient Master Whom all creatures need.' (Surat Al- Ikhlas 112 ) is equal to one third of the Qur'an."!! ﺳﺒﺤﺎﻥ ﺍﻟﻠﻪ !!
