Signs of Faith in Allah
1- Hope and Feeling of Love: Anyone who knows that all his deeds are accounted for, and that his efforts do not go in waste, and also that Allah rewards him for his actions and deeds with Paradise, though He by His benign Mercy sometimes bestows upon him rewards for his good intentions too, he then leads his life with his love for Allah in a state of cheerful hopefulness.
2- Abstains from Corruption: Such a man abstains from treachery, meanness, and hypocrisy. Anyone who considers himself to be ever-present before Allah and considers Allah as Omniscient can never practice deceit and hypocrisy.
3- Preserves His Self-respect: He, who has submitted himself to the Will of Allah and truthfully obeys His commands, can never bow down before anyone in authority, status and power. He considers everybody as he himself is.
4- He is Never in Loss: Since the man of faith benefits by his timely deed and receives an everlasting reward from Allah and pins his hopes only on Allah, he never sustains any loss at all.
5- Tranquility: If we look into the following causes of fear and restlessness, we find that faith in Allah provides a complete peace, satisfaction and a state of tranquility Causes of Fear and Worries
(a) Sometimes past lapses and bad deeds are the causes of one’s fears and worries but the remembrance of Allah changes this state of mind into that of peace and tranquility because Allah is Merciful and Benevolent and He forgives sins and accepts one’s repentance.
(b) Sometimes loneliness and the very thought of helplessness leads to fears and worries but the faith that Allah is Omnipresent and Omniscient changes this state of mind into that of peace and tranquility. The man believes that Allah is not only our Companion and Compassionate but He hears us, sees our deeds and bestows His blessings on us.
(c) Sometimes the aimless life and the sense of lethargy make one’s mind restless but the faith in Allah removes all such fears and worries as Allah has created everything in this world with a purpose by His Wisdom in a definite quantity and number within a specific sphere.
(d) Sometimes a man gets worried that he has not been able to please everybody, and he broods over the thought that he annoyed or provided the cause of displeasure to a particular person or a group of persons, but the faith in Allah that one should only try to please Allah as honor and disgrace only come from Him removes that state of restlessness. And it is confirmed by the Holy Qur’an which says: ﴾Remembrance of Allah certainly brings comfort to all hearts.﴿ (13:28)
Signs of Dishonesty
He who does not have faith in the real cause of the Creation, that is Almighty and All-Wise Allah, is a person, who finds himself shaky, aimless and lonesome and concerns himself like animals and birds with the enjoyment of the comforts of worldly life only; who acts only under the pressure of the society; who considers death the last thing in life, and does not have the belief in the life after death as he does not believe in the immortality of soul; who surrenders his life to be dominated by external powers and his personal desires; who is beset with vague ideas and notions, deprivation, faults and lapses as his article of faith has not been guided by the infallible Prophets and Divine revelations, who is completely unaware of the very purpose of life. He does not know as to why he has come to this world and why he is departing from this world. His only line of thinking is as to how his life should be spent? He does not realize the very purpose of life. He is devoid of the Divine Approach to Universe and Islamic faith.
In short, one can detect faith from the face of those who have belief in Allah and of those who have no belief in Allah.
