How much remembrance is asked for
The only act of worship the Qur'an commands without an upper limit.
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱذْكُرُوا۟ ٱللَّهَ ذِكْرًا كَثِيرًا وَسَبِّحُوهُ بُكْرَةً وَأَصِيلًا
Yā ayyuha-lladhīna āmanu-dhkuru-llāha dhikran kathīrā, wa sabbiḥūhu bukratan wa aṣīlā.
“O you who have believed, remember Allāh with much remembrance And exalt Him morning and afternoon.”
