Surah 49. Al-Hujurat, Ayah 16

Like the preceding passage, this, too, is addressed in the first instance to certain contemporaries of the Prophet, but its meaning extends to all people, at all times, who think that their mere profession of faith and outward adherence to its formalities makes them "believers".

'You say (or perhaps even think) that you are Muslims, but where are the fruits of your Faith? Allah knows the innermost motives and secrets of your heart, and you cannot deceive Him by attaching a certain label to yourselves'. Alas! that this answer to the desert Arabs is true of so many others in our own times!
