Surah 40. Ghafir, Ayah 13

Lest it should be thought that Allah's Grace did not meet the Sinner again and again and offer Allah's Mercy again and again, it is pointed out that Allah's Signs were freely vouchsafed everywhere and continuously, and that every kind of means was provided for man's "Sustenance" or growth and development, physical, mental, and spiritual. But only those could take advantage of it who turned their attention to Allah, who submitted their will to Him.
