Importance of perfecting rukūʿ (bowing) and sujūd (prostration)

Ḥudhayfah saw a person who was not bowing and prostrating perfectly ˹in prayer˺. He said to him, "You have not prayed; and if you should die you would die on a fiṭrah (natural disposition) other than that of the fiṭrah of Muhammad ﷺ."  

رَأَى حُذَيْفَةُ رَجُلاً لاَ يُتِمُّ الرُّكُوعَ وَالسُّجُودَ قَالَ: مَا صَلَّيْتَ؛ وَلَوْ مُتَّ، مُتَّ عَلَى غَيْرِ الْفِطْرَةِ الَّتِي فَطَرَ اللَّهُ مُحَمَّدًا ﷺ۔
