You're highlighting a key distinction in Islamic prayer times and asking why combining specific prayers isn't generally permissible. Here's a breakdown of the reasoning:
* Established Times: Islamic prayers (Salat) have specific, divinely ordained times. These times are based on the position of the sun. While there's some flexibility in certain situations, the general rule is adherence to these established times.
* Zohar (Zuhr) and Assar (Asr) / Maghrib and Isha Separation: There's a defined period between Zuhr and Asr, and between Maghrib and Isha. These periods, while variable, are not meant to be skipped entirely.
* Jam' (Combining Prayers): In specific circumstances, Islam allows for the combining (Jam') of prayers. The most common instances are:
* Travel: A traveler may combine Zuhr and Asr, or Maghrib and Isha.
* Illness: Someone who is ill and finds it difficult to pray at separate times may combine prayers.
* Necessity: In rare cases of extreme necessity or hardship, combining prayers may be permissible.
* Conditions for Combining: When combining prayers, there are specific conditions:
* Intention: The intention (Niyyah) to combine prayers must be made before the time of the first prayer expires.
* Order: Generally, the prayers are performed in their original order (e.g., Zuhr before Asr).
* Continuity: There shouldn't be a long break between the two prayers.
* Default is Separation: The default and recommended practice is to pray each prayer within its designated time. Combining prayers is an exception, not the rule.
* Wisdom: The separation of prayer times serves several purposes:
* Discipline: Reinforces discipline and adherence to Allah's commands.
* Remembrance: Provides regular reminders of Allah throughout the day.
* Connection: Allows for multiple opportunities to connect with Allah and seek His guidance.
In summary, while combining prayers is allowed in specific situations due to hardship or necessity, it's not the standard practice. The established prayer times are a fundamental aspect of Islamic worship, and adhering to them is generally considered the more virtuous and rewarding path.
