Truly man is in loss-except for those who believe and do right actions and urge each other to the truth and steadfastness. (Surat al-'Asr, 2-3)
Patience leads to intelligence
However, the believers who always remain patient, as Allah counsels them, acquire great blessings, one of which is intelligence. As a result, they do not suffer from sudden fear, nervousness, or emotional excess. This enables them to evaluate all events in a calm and self-possessed manner and thereby arrive at the most intelligent conclusions and the most beneficial decisions.
Even more important, this patience allows the faithful to follow all of the Qur'an's teachings in the best possible way. Since believers always behave patiently, they have the opportunity to act only after evaluating events in light of the Qur'an's teaching. Those who follow the Qur'an are directed toward the true path of Allah and toward the finest behavior. For these reasons, following the Qur'an in the best possible way enables believers to gain the superior intelligence that derives from its wisdom.
Patience ensures subtle thought and the ability to see details
The faithful, always remaining patient, do not succumb to unnecessary haste while solving a problem. Understanding that haste is a primary factor of people's inability to use their intelligence and think correctly, they consider all details and make accurate decisions. Knowing how to act according to their intelligence without rushing, believers proceed intelligently, easily see those complexities that might be invisible to others, and thus adopt the most correct behavior.
Patience ensures the ability to do good
As for the faithful, they have an inner awe of Allah and know that they will find in the afterlife beauty and blessings commensurate to what they have done for Him. For this reason, they show determination and patience by always behaving well and making a serious effort. Thus they purge themselves of all bad characteristics and find the opportunity to turn these into good characteristics.
Patience ensures just behavior
Those who are expected to ensure justice must not give way to their emotions, succumb to anger, or act from such motives as hatred and revenge. When they encounter such a situation, they must display serious patience. Allah informs us of this, as follows:
O you who believe, show integrity for the sake of Allah, bearing witness with justice. Do not let hatred for a people incite you to injustice. Be just. That is closer to heedfulness. Heed Allah. Allah is aware of what you do. (Surat al-Ma'ida, 8)
Patience gives believers a trustworthy character
Indeed, Iam to you a trustworthy messenger. (Surat ash-Shu'ara', 143)
Most important, their continual patience at all times allows them to behave with determination in displaying this fine characteristic as long as they are alive. They make no concession to worldly profit in their behavior, a trait that pleases Allah. All of these elements together, along with living in a consistent manner, make the faithful the most trustworthy of all people.
Patience gives a person a cheerful and peaceful character
When We give people a taste of mercy, they rejoice in it. But when something bad happens to them because of what they themselves have done, they immediately lose all hope. (Surat ar-Rum, 36)
The believers who can appreciate Allah's greatness and boundless mercy take refuge in Him with patience and trust, regardless of the difficulties, problems, or events that they may be experiencing. As a result, they never lose any of their cheerfulness and tranquility, even when experiencing their most difficult moments, for they know that Allah will give them a fine recompense in Paradise for the patience they displayed in this world. Therefore, they live their lives in great joy and enthusiasm.
Those who cannot show patience when confronted with adversities are condemned to spend their worldly lives in unhappiness. Allah points out that they will be unhappy in the afterlife as well. The Qur'an describes the rewards that those who are patient (the believers) and those who are impatient and therefore rebellious toward Allah (the unbelievers) will receive in the afterlife, as follows:
On the Day it comes, no one will speak except with His permission. Some of them will be wretched and others will be glad. As for those who are wretched, they will be in the Fire, where they will sigh and gasp, remaining in it timelessly, forever, as long as the heavens and Earth endure, except as your Lord wills. Your Lord is the Doer of what He wills. As for those who are glad, they will be in Paradise, remaining in it timelessly, forever, as long as the heavens and Earth endure, except as your Lord wills. An uninterrupted gift. (Surah Hud, 105-108)
The wonderful life Allah promises to the faithful
He sent down serenity into the hearts of the believers, thereby increasing their faith with more faith-the legions of the heavens and Earth belong to Allah. Allah is All-Knowing, All-Wise. (Surat al-Fath, 4)
In return for their unconditional submission, patience, and pleasant acceptance of everything that our Lord sends to them, Allah tells them that He will give them a beautiful life in the world:
Anyone who acts rightly, male or female, being a believer, We will give them a good life and recompense them according to the best of what they did. (Surat an-Nahl, 97)
As for those who do their duty and are steadfast, Allah does not allow to go to waste the wage of any people who do good. (Surah Yusuf, 90)
When those who have done their duty are asked: "What has your Lord sent down?" their reply is: "Good!" There is good in this world for those who do good, and the abode of the Hereafter is even better. How wonderful is the abode of those who guard against evil. (Surat an-Nahl, 30)
Say: "Servants of Mine who believe, heed your Lord. For those who do good in this world there is good, and Allah's Earth is spacious. The steadfast will be paid their wages in full without any reckoning." (Surat az-Zumar, 10)
The believers' reward for being patient is Paradise
The finest reward that the faithful can obtain in the afterlife for this outstanding patience is Allah's love, generosity, and approval:
Allah has promised the male and female believers Gardens with rivers flowing under them, remaining in them timelessly, forever, and fine dwellings in the Gardens of Eden. And Allah's good pleasure is even greater. That is the great victory. (Surat at-Tawba, 72)
Their Lord gives them the good news of His mercy, good pleasure, and Gardens in which they will enjoy everlasting delight. (Surat at-Tawba, 21)
Their reward is with their Lord: Gardens of Eden with rivers flowing under them, remaining in them timelessly, forever and ever. Allah is pleased with them, and they are pleased with Him. That is for those who fear their Lord. (Surat al-Bayyina, 8)
Gardens of Eden that they will enter, and all of their parents, wives, and children who were righteous. Angels will enter in to welcome them from every gate: "Peace be upon you because of your steadfastness! How wonderful is the Ultimate Abode!" (Surat ar-Ra'd, 23-24)
They will be given their reward twice over, because they have been steadfast… (Surat al-Qasas, 54)
Such people will be repaid for their steadfastness with the Highest Paradise, where they will meet with welcome and with "Peace." (Surat al-Furqan, 75)
Today I have rewarded them for being steadfast. They are the ones who are victorious. (Surat al-Mu'minun, 111)
