Ṣawm — fasting the month of Ramadan — is the fourth pillar of Islam.

Allah prescribed it for this community as He prescribed it for those before, and named its purpose plainly:

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُتِبَ عَلَيْكُمُ ٱلصِّيَامُ كَمَا كُتِبَ عَلَى ٱلَّذِينَ مِن قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ

Meaning: O you who have believed, fasting has been prescribed for you as it was prescribed for those before you, that you may become mindful of Allah.

That closing word — taqwā — is the point of the month: awareness of Allah, reverence, and the restraint that follows from both.

What does the Ramadan fast involve?

From the arrival of true dawn until sunset, a Muslim abstains from food, drink and marital relations. The Qur’an sets both ends of the daily fast:

“…and eat and drink until the white thread of dawn becomes distinct to you from the black thread. Then complete the fast until the night.” (al-Baqarah 2:187)

But the fast was never only about hunger and thirst. It should also press a person to:

  • Guard the tongue from lying and harmful speech.
  • Hold back anger and poor behaviour.
  • Increase prayer and remembrance.
  • Read the Qur’an and reflect on it.
  • Show patience, generosity and mercy.

Why is Ramadan tied to the Qur’an?

Because it is the month in which the Qur’an was sent down:

شَهْرُ رَمَضَانَ ٱلَّذِىٓ أُنزِلَ فِيهِ ٱلْقُرْءَانُ هُدًى لِّلنَّاسِ وَبَيِّنَـٰتٍ مِّنَ ٱلْهُدَىٰ وَٱلْفُرْقَانِ ۚ فَمَن شَهِدَ مِنكُمُ ٱلشَّهْرَ فَلْيَصُمْهُ ۖ وَمَن كَانَ مَرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ ۗ يُرِيدُ ٱللَّهُ بِكُمُ ٱلْيُسْرَ وَلَا يُرِيدُ بِكُمُ ٱلْعُسْرَ وَلِتُكْمِلُوا۟ ٱلْعِدَّةَ وَلِتُكَبِّرُوا۟ ٱللَّهَ عَلَىٰ مَا هَدَىٰكُمْ وَلَعَلَّكُمْ تَشْكُرُونَ

Meaning: The month of Ramadan is that in which the Qur’an was revealed, a guidance for the people and clear proofs of guidance and criterion.

That makes Ramadan the natural time to rebuild your relationship with the Qur’an — through recitation, understanding, and acting on what you read. A thirty-day reading plan makes the whole Qur’an achievable across the month.

What about illness and travel?

The same verse gives the concession: whoever is ill or on a journey may fast an equal number of other days instead. Allah states in it that He intends ease for you, and does not intend hardship for you.

Other situations — pregnancy, breastfeeding, chronic illness, advanced age — carry detailed rulings of their own. If any of these apply to you, seek both reliable scholarly guidance and medical advice rather than putting yourself at risk.

The reward of a sincere fast

The Prophet ﷺ taught that whoever fasts Ramadan out of faith and in hope of Allah’s reward will have their previous sins forgiven.

Fasting trains a believer to leave even lawful things for Allah’s sake. That training is meant to outlast the month — in self-control, in gratitude, and in obedience once the month has gone. The last ten nights deserve particular attention; see what to read and do on Laylat al-Qadr.
