To attain al-Khushoo one must forget everything about the world and concentrate in the prayer acts, reciting the Qur'an and thinking of the verses one reads and bearing death, grave and the torment in mind so that he never loses concentration. In his Tafseer, Ibn Kathir writes, ""Khushoo is gained by the fear of Allah and the sense that He is always watching."" In another section he says, ""The site of al-Khushoo is in the heart and heart is the king of the limbs, so if one intends to pray wholeheartedly the limbs will follow the heart as Allah says (in the Qur'an): 'And seek help in patience and Salaat and truly it is extremely heavy and hard, except for Khashi'oon.' The meaning is that the burden of prayer is heavy indeed; except for those who have Khushoo.""
