Today starts the month of Ramadan, and having just returned from Morocco, I was speaking to a number of people preparing for the difficult month ahead, in which they will fast during the hours of sunlight.
David Cameron has sent his very best wishes to Muslim communities in Britain and around the world, as they start the month of Ramadan.
He said: "I know the significance this month has for all Muslims", he said, "and there are lessons which members of all faiths and none can learn from this observance. These include the importance of reflection, charity and self-control."
He added that these are principles which help to strengthen society as a whole, and "are a sign of the contribution which Muslim communities and the Muslim faith has made to our national life".
