"(Believers are) those to whom people said, "The people have gathered against you, so fear them." But that merely increased their faith and they said, "Allah is enough for us and the Best of Guardians." [Al-Imran:173]
The mosque of Allah shall be maintained only by those who believe in Allah and the Last-Day; perform the Shalah, and give the Zakah, and fear none but Allah. It is they who are on true guidance." [al-Taubah: 18]
It is only those who have knowledge among His slaves that fear Allah. Verily Allah is All Mighty , Oft-Forgiving. [Fatir: 28]
True Islamic courage (syaja'ah), as outlined in the Qur'an, is showing determination in respecting all of Allah's limits, without exception, and without hesitation, fearing none other than Allah, and not deviating from this course whatever the circumstances. Essentially, courage is the virtue that arises as a result of faith, in those who fear no one but Allah, and who are deeply devoted to Him. The very basis of the courage of the faithful is their love and fear of Allah, and their rendering sincere effort to earn His good pleasure. For that reason, their courage in fulfilling the requirements of morality is not dependent on specific circumstances. Those who believe in Allah show courage as an outcome of their fear of Allah and their longing for the Hereafter. Because they are sincere, they are also courageous and brave. And only most courageous and brave are the people of knowledge.
"Then we have put you (O Muhammad peace be upon him) on a (plain) way of (Our) commandment and laws, so follow." [al-Jathiyah: 18]
"Verily, those who say: "Our Lord is Allah (Alone), and then they stand firm, on them the angels will descend (at the time of their death) (saying): "Fer anot nor grieve! But receive the glad tidings of Paradise which you have been promised" [Fussilat: 30]
True Islamic discipline is reflected through consistent adherence to the rules and regulations (al-Ittiba') and remain steadfast (al-Istiqamah) with continuous obedience and positive belief in our doings.
"Successful indeed are the believers……..those who are faithfully true to their amanah (trusts) and to their covenant." [al-Mu'minun: 1-8]
"O you who believe! Fulfill your promise" [al-Ma'idah: 1]
Islamic trustworthiness (al-Amanah) is reflected in Muslims' words and dealings. Muslims with this virtue are Muslims with high degree of Honesty and Integrity. They are responsible to be honest and trusted by colleagues and partners.
"Truly, my prayer and my devotions, my life and my death, are (all) for Allah, the Cherisher of the Worlds." [al-An'am: 162]
"O you who believe, obey Allah and obey the Messenger (Muhammad peace be upon him)and those of you who are in authority. And if you differ in anything amongst yourselves, refer it to Allah and His Messenger (peace be upon him) if you believe in Allah and the Last Day, that is better and more suitable for determination." [al-Nisa: 59]
One of distinguishing features of believers is a sense of loyalty - Islamic loyalty. Muslims, in their real sense, are loyal and very much against on self-interest motivation. Loyalty keeps them fight for their faith directed towards one goal. This attribute, the essential characteristic of determination, is vital for any community of believers that is steadfast. A Muslim would fail to keep his self-respect if even once he demonstrated a minor neglect in his loyalty. Once one loses self-respect completely, one gradually approaches a point where one loses faith.
"And strive hard in Allah's Cause as you ought to strive (with sincerity and efforts)." [al-Haj: 78]
"Allah has conferred on those who strive with their wealth and their lives a rank above those who sit still." [al-Nisa: 95]
"As for those who strive hard for Us, surely We shall guide them to Our path, and truly Allah is with the good." [al-'Ankabut: 69]
Islamic diligence is an expression of enthusiastic interest and sincere devotion to a cause in accomplishing it. Muslims are those who never lose the enthusiasm in their hearts throughout their lives. They continue to strive hard towards precision in all matters, to be the best of all. This is due to the source of their diligence is faith in Allah and their major goal is earning the good pleasure of Allah, His mercy and His Paradise.
