Shaikh Haji Shakeel Ahmed (Allah preserve him) said in regards to praying with concentration that Allah is watching me,

‘A tip to improve one’s salah is to offer two rakat daily with intention of forwarding its reward (esal e thawab) to our master Prophet Muhammed (Allah bless him and grant him peace).

This noble association (nisbet) will make one strive more for perfection in salah.

All praise is to Allah. Many individuals have tried this and found it to be very beneficial in improving their salah.’
