Invisible Forces that Shape our Day

Social Contagion

Yesterday we spoke about routines — how our habits run on autopilot and shape our mornings without us deciding. Today we look at another invisible force: social contagion.

Now, don’t let the word contagion alarm you. We’re not talking about sickness. We’re talking about how moods, behaviours, attitudes, and even small habits spread from person to person — like a ripple in water — without us ever noticing.

Have you ever been in a room where someone was quietly angry, and suddenly you felt tense without knowing why? Or have you ever been around a person who was genuinely cheerful, and you found yourself smiling for no reason? That is social contagion. It is the invisible transfer of emotion and behaviour from one human being to another.

Allah ﷻ created us as social creatures. We influence one another constantly. The Prophet Muhammad ﷺ gave us a powerful warning about this when he said:

عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ‏ الرَّجُلُ عَلَى دِينِ خَلِيلِهِ فَلْيَنْظُرْ أَحَدُكُمْ مَنْ يُخَالِلُ ‏

“A person is likely to follow the faith of his close friend, so look carefully at whom you befriend.” (Abu Dawud, Tirmidhi)

This hadith is not only about theology — it is about behaviour. The people around you shape you. Their habits, their attitudes, their energy — all of it transfers to you like water soaking into cloth.

And here is the invisible part: you don’t feel it happening. You don’t wake up one day and say, “Today I will adopt my colleague’s sarcastic tone.” It just seeps in. You spend enough time with someone who complains constantly, and soon you find yourself complaining more. You sit with someone who backbites, and eventually your own tongue becomes loose. Conversely, you sit with someone who remembers Allah often, and your own heart softens.

This is why the Qur’an repeatedly warns us about the company we keep. Surah Al-Furqan, verse 28, describes the regret of the wrongdoer on the Day of Judgement:

يَـٰوَيْلَتَىٰ لَيْتَنِى لَمْ أَتَّخِذْ فُلَانًا خَلِيلًا

“Oh, woe to me! I wish I had never taken so-and-so as a close friend.”

That regret comes from realising, too late, how much of their bad behaviour had transferred to them.

But social contagion also works for good. The Prophet ﷺ gave a beautiful example of this too. He said:

“The example of a good companion and a bad companion is like that of a musk seller and a blacksmith. The musk seller will either give you perfume, or you will buy some from him, or at least you will smell a pleasant scent from him. As for the blacksmith, he will either burn your clothes, or you will smell a foul odour from him.” (Bukhari, Muslim)

So the question is not if you are being influenced — you are. The question is: who is influencing you, and towards what?

Invisible forces are powerful precisely because they are invisible. You cannot fight what you do not see. So today, I invite you to do a quiet audit of your close circles. Think about the people you spend the most time with — at work, in your family, in your friends group. After being with them, do you feel closer to Allah or further away? Do you feel more patient or more irritable? Do you find yourself speaking better or worse of others?

This is not about cutting people off harshly. This is about awareness. Once you see the contagion, you can protect yourself — by increasing your own remembrance of Allah, by being intentional about the energy you carry, and by gently seeking better company when you can.

And remember: you are also contagious to others. Your smile, your patience, your dhikr, your good character — all of it spreads too. Be the person who spreads good contagion in your home, your workplace, and your community.
