(63) باب الرُّكُوعِ دُونَ الصَّفِّ
It was narrated that Abu Hurairah said:
"The Messenger of Allah (ﷺ) prayed one day then left and said: '0 so-and-so, why don't you improve your prayer? Shouldn't the one who is praying reflection how he prays it for himself? I can see behind me just as I can see in front of me."'
