No, it is not Haram (forbidden) to fast on Monday in Islam. In fact, fasting on Mondays is a Sunnah (recommended practice) of the Prophet Muhammad (peace be upon him).
Here's a breakdown:
- Fasting on Mondays is a Recommended Sunnah: The Prophet Muhammad (PBUH) used to fast on Mondays (and Thursdays) regularly. This makes it a highly encouraged voluntary act.
- Why Mondays? He was asked about fasting on Mondays and Thursdays, and he said that his actions were due to the fact that actions are presented to Allah on these days.
- Voluntary Nature: Fasting on Mondays is not obligatory. You are not sinful if you choose not to fast. It's an act of worship that carries reward if you observe it.
- No Obligation to Pair: While Mondays and Thursdays are both days the Prophet fasted on, you are not required to fast on both. Fasting on either Monday or Thursday individually is perfectly acceptable and carries its own reward.
In summary, fasting on Mondays is a virtuous and recommended practice in Islam, following the example of the Prophet Muhammad (PBUH). It is not Haram.
