has stated: Allah عَزَّوَجَلَّ has given two kinds of parts to humans, one external and the other is concealed. The apparent/external parts are the face, eyes, nose, ears etc., and the hidden parts are the heart, brain, liver, etc. A Muslim can be of perfect faith when he is a Muslim in appearance and also in the heart, that is to say, he should act upon Islam in a way that it must be visible from his appearance and conduct; the passion for obeying Allah عَزَّوَجَلَّ and the Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم should be in his heart; the candle of faith should be burning in it and his face should be liked by the Beloved Prophet   صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم. That is to say, it should be like a Muslim. If there is faith in the heart but the face resembles a non-Muslim, then one has not entered completely into the folds of Islam. Conduct and appearance should both be good. An Islamic appearance and Islamic wear have many advantages:

1.         The Government has formed numerous departments such as for the railway, post office, police, army and court etc. and for every department different uniforms have been selected so that they can be recognized as to which department a person belongs to from those numerous departments. If a government servant is not wearing his uniform during duty, he is fined; if he is informed again and again and he does not obey, then he is dismissed. Similarly, we are also the servants of the department of Islam, the kingdom of Beloved Mustafa صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم and the government of Allah عَزَّوَجَلَّ. Different appearances have been chosen for us as well in order to be recognized as the slaves of the Beloved Mustafa صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم among millions of unbelievers. If we do not wear our uniform, we will also deserve punishment.

2.         Nature has had such a relation between human external appearance and the heart that both affect each other. If you are sad at heart, then there is sadness on your face as well and the beholder says: Are you alright? Why are you sad? If there is joy in your heart, then the face lights up. It has become obvious that the heart affects the face. Likewise, if somebody is suffering from TB, the doctor says that he should be kept in fresh air and be made to wear good and clean clothes and should be given a bath from so-and-so medicinal water. As a matter of fact, the disease is in the heart but why is this external body given the treatment.
