Life in this world continues with its ups and downs. Human soul is like a guest house. Not just sorrows and afflictions but also happiness and goodness of this world are like its guests. None of them are permanent. This is why a believer should not disrupt the order and tranquility of this world by feeling too much happiness or sadness in the face of varied incidents of this mundane world.

The perfect life of the Messenger of Allah (pbuh) is full of manifestations of sadness and suffering. Further, he states this in the following saying

“No one has suffered in the way of God as much as I have.” (Tirmidhī, Qiyāma, 34/2472)

However, none of his suffering hindered his balance and resolution. He (pbuh) confronted all of them with maturity and contentment. Even though his soul was full of sorrow, his face never went without a smile. Nobody ever saw him frown or with sullen face; because, he was always smiling in peace and tranquility for being in the presence of Allah the Almighty and manifesting the smiling face of Islam under any circumstances.

The goodness of the inner beauties of the Companions of the Prophet (pbuh) and the friends of Allah, who were annihilated themselves in the Prophet (Fanaa fi al-Rasūl), has manifested in their faces. Umm al-Dardā (r.a) narrates that:

“When Abū al-Dardā was talking, he always smiled. One day I told him:

“I am worried about that people might think your smile weird and admonish you” and he replied:

“The Messenger of Allah r certainly smiled, when he was talking about something.” (Aḥmad, V, 198, 199)

Constant smile of the Messenger of Allah (pbuh) is the best manifestation of his restful unity with Allah the Almighty.

Every human being feels pleasure from being happy; however, like in everything else, there has to be a balance and an appropriate limit in feeling happiness. Just like it is wrong to destroy one’s self because of the suffering faced in this world, it is also wrong to show too much joy and pleasure before the felicitous incidents of the world.

Both of these states damage the human dignity and personality. A believer should always have a sensitive and delicate heart. And he should always have smile on his face. Smile is the dignity of a believer in comparison to the levity of laughing. On the other hand it is also the charm of a believer contrary to the repulsiveness of a sullen face.

Jalal al-Dīn Rumī makes a subtle warning about that even an ordinary act like smiling may give clues about the character of a person and says that:

“From how he smiles, I understand the quality of his manners; and from what he smiles at, I understand his level of his intelligence.”

Excessive laugh sometimes impels a person to heedlessness and makes him forget that he is being tested in this world. Forgetting that the real happiness is in the Hereafter results in slavery to the mundane pleasures of the self. Long and continuous laughs poison the soul, darkens the heart, and causes it to lose its sensitivity.Omar t makes the following warning about the dangers of excessive laughing:

“Those who laugh excessively lose their dignity. Those who make too much jokes are teased. Everybody gets to be known with the things they do most. Those who talk too much make too much mistakes. Those who make too much mistakes lose their shame. Those who lose their shame avoid the questionable things less. The hearts of those who avoid the questionable things die.” (Ghazālī, Iḥyā, III, 288)

Heedlessness, which is the most significant spiritual disease, deceives human by showing him that his happy life in this world is eternal. Heedlessness distracts his attention and makes him forget the main problems of a human being in this world like death, resurrection, judgment day, and afterlife.

This characteristic of a human being is stated in the following verse:

“And will you laugh and not weep? While you are indulging in varieties.” (53; 61)

In this respect, the Messenger of Allah (pbuh) says that:

“If you but knew what I know then you would have laughed little and wept much.” (Bukharī, Tafsīr, 5/12)

Jalal-al-Dīn Rumī also explains this fact as follows:

“The wise, indeed, make lamentations at first and smile later; the foolish, on the other hand, smile at first and beat their heads at the last. O people! From the beginning of the affair discern the end (thereof), so that you may not be repenting on the Day of Judgment.”

In this regard Imam Ghazālī narrates the following story.A man asked his brother, who was laughing exaggeratedly:

“What is the matter? Did you get news that you have been saved from Hellfire?” His brother said: “No, I did not.” The man asked again: “Then how can you laugh so much?” (Ghazālī, Iḥyā, III, 288)

None of the servants of Allah except His prophets are guaranteed to enter the Paradise. Wahb b. Ward (may Allah have mercy his soul) gave the following advice to the people, when he saw them laughing on a holiday:

“If your sins are forgiven, this is not the manner of those who feel gratitude. If your sins are not forgiven, then this is not the state of those who are afraid of Divine Punishment.” (Ghazālī, Iḥyā, III, 288)

Muhammad b. Waṣī (may Allah have mercy his soul) says that:

“The laughs of those, who do not know whether they will be in heaven or in Hell are as weird as the cry who is already accepted in Heaven.” (Ghazālī, Iḥyā, III, 289)

This conduct consists of an important aspect, which Islamic ethics helps its followers to gain. Therefore even if a believer has great volcanoes boiling in his heart, his face should spread serenity like a peaceful harbor. He should neither be too relaxed with joy nor be pessimistic with extreme grief.

A believer should develop a moderate state in his heart between hawf and raja’. Hawf means not to be spoiled from good deeds and to be in a state of both continuous supplication and fear Allah’s punishment. Raja’, on the other hand, means to be hopeful of His mercy and not to be pessimistic.

Khalid al-Baghdādī explains this state of the heart to one of his disciples in a letter:

“I swear Allah that I do not believe that I have performed a single action which is acceptable by Allah and won’t be questioned before Him since the day I was born… (I only hope my Lord’s mercy) …Please do not forget to pray for this poor servant’s success and for him to have a good last breath.”

A smiling face, which is an essential characteristic of a believer, also shows the level of this state of moderation. However, even a praised behavior, such as smiling, has calamities and the calamity of smiling is to do it with wrong intentions. Smiling out of wrong intentions such as pride, scoffing, looking down to brothers in Islam will have serious consequences in the Hereafter.

When Ibn Abbas (r.a) was interpreting the word “small or large” in the verse “They will say, “Woe to us. How come this book leaves nothing, small or large, without counting it?”…” (18; 49),

he says that: “small means smiling when mocking with a believer, while large sin, on the other hand, is laughing meanwhile.” (Ghazālī, Iḥyā, III, 294)
