[Machine] Allah commanded His Prophet ﷺ to perform fifty prayers. He asked his Lord ﷻ to reduce them, and so it was made five prayers.
فَرَضَ اللهُ ﷻ عَلَى نَبِيِّهِ ﷺ الصَّلاةَ خَمْسِينَ صَلاةً فَسَأَلَ رَبَّهُ ﷻ فَجَعَلَهَا خَمْسَ صَلَوَاتٍ
[Machine] I heard Ibn Abbas say, "Fifty prayers were initially obligated upon your Prophet ﷺ, but he asked his Lord, the Mighty and Majestic, who made them five."
سَمِعْتُ ابْنَ عَبَّاسٍ يَقُولُ فُرِضَ عَلَى نَبِيِّكُمْ ﷺ خَمْسُونَ صَلاةً فَسَأَلَ رَبَّهُ ﷻ فَجَعَلَهَا خَمْسًا
