The five (daily) prayers and one Friday prayer to (the next) Friday prayer are expiations (for the sins committed in the intervals) between them.
The Book of Purification - Sahih Muslim 233b
This hadith, narrated in Sahih Muslim, establishes the profound mercy of Allah towards the believers. The five daily prayers and the Friday prayer serve as continuous means of spiritual purification and atonement for minor sins committed between them, provided major sins are avoided.
Exegesis of the Text
The "expiations" (kafarat) mentioned refer to the erasure of minor sins. This is a manifestation of Allah's infinite grace, making the prescribed acts of worship a source of ongoing forgiveness and a means to maintain spiritual cleanliness.
This expiation is conditional upon the avoidance of major sins (kaba'ir), which require specific repentance (tawbah). The prayers thus act as a regular spiritual maintenance, preventing the accumulation of minor transgressions.
The Wisdom of Sequential Purification
The sequence from daily prayers to the weekly Jumu'ah prayer creates a layered system of forgiveness. The daily prayers cleanse the believer on a short-term cycle, while the Friday prayer offers a more comprehensive weekly spiritual renewal, symbolizing a fresh start.
Scholarly Interpretation
Classical scholars emphasize that this hadith highlights the immense value of maintaining the obligatory prayers with their conditions, times, and pillars intact. It is the correctly performed prayer, with presence of heart and humility, that carries this expiatory quality.
This tradition serves as a powerful incentive for consistency in worship, transforming the daily and weekly religious obligations into a continuous journey of self-purification and drawing nearer to the Divine.
