His saying, "The month of Ramadan in which the Quran was revealed as guidance for the people and clear proofs of guidance and criterion. So whoever among you witnesses the month, let him fast it, and whoever is ill or on a journey, then a number of other days. Allah intends ease for you and does not intend hardship for you, and so that you may complete the number and glorify Allah for having guided you, and that you may be grateful."
