Hunaidah Al-Khuza'i said: "I entered upon the Mother of the Believers and heard her say: 'The Messenger of Allah used to fast three days of each month: The first Monday of the month, then Thursday, then the following Thursday".
Fasting is one of the five pillars of Islam which are obligatory for all Muslims who have reached puberty or are mentally mature enough to understand its importance. It is a way for us to show gratitude towards Allah by abstaining from food and drink during certain times throughout the day during Ramadan or other months in order to gain spiritual rewards from Him. Additionally, it helps us become more mindful about what we consume as well as teaches us patience and perseverance when faced with difficult situations in life.
