Ramadan is a blessed month for Muslims, in which they fast from dawn to sunset, pray, read the Quran, and perform acts of charity. Some of the lessons that a Muslim learns from the month of Ramadan are:

• Self-restraint is a positive universal concept that helps us control our desires and impulses and avoid harmful habits and sins.
• All people struggle in one way or another, and fasting helps us empathize with those who are less fortunate and face hardships in life.
• Tolerance goes a long way, as fasting teaches us patience, perseverance, and forgiveness.
• Food always brings people together, as fasting makes us appreciate the blessings of Allah and share them with others in Iftar gatherings.
• We should celebrate diversity, as fasting reminds us that we are part of a global community of Muslims who have different languages, and backgrounds but share the same faith and values.
• Gaining taqwa (consciousness of Allah) is the main goal of fasting, as it helps us obey Allah, follow His guidance, and seek His mercy.
• Praying regularly and performing voluntary prayers (nawafil) is another lesson of Ramadan, as it strengthens our connection with Allah and increases our reward.
• Being compassionate and caring is another lesson of Ramadan, as it inspires us to help the poor and needy, and to feel the sense of unity and brotherhood among Muslims.
