﴿ حَٰفِظُوا۟ عَلَى ٱلصَّلَوَٰتِ وَٱلصَّلَوٰةِ ٱلْوُسْطَىٰ وَقُومُوا۟ لِلَّهِ قَٰنِتِينَ ﴾

“BE EVER mindful of prayers, and of praying in the most excellent way; and stand before God in devout obedience.”

Allah then prompted the believers to observe the five daily prayers, saying: (Be guardians of your prayers) the five daily prayers including the ritual ablution that precede them, their bowings, prostrations, and everything prescribed in them during their appointed times, (and of the midmost prayer) the 'Asr prayer specifically, (and stand up with devotion to Allah) pray to Allah, by performing the bowings and prostrations this prayer includes; it is also said that this means: pray to Him by being obedient to Him in the prayer and not disobedient through engagement in mundane talk.
