How can we attain Khushu` (the heart being submissively attuned to the act of worship) while performing Salah (Prayer) and reciting the Qur'an?
You should ask Allah to help you attain Khushu` in Salah. You should also seek refuge with Allah from Satan and his Waswasah (insinuating thoughts from Satan). Allah is All-Hearer, Ever-Near and Responsive; He responds to the sincere and truthful invocations of the supplicant. May Allah grant you success and help you constantly remember and thank Him. (Part No. 7; Page No. 28) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family and Companions.
