قَالَ الْحَسَن البصري رحمه الله:

كُلُّ صَلَاةٍ لَا يَحْضُرُهَا قَلْبُكَ فَهِيَ إِلَى الْعُقُوبَةِ أَسْرَعُ مِنْهَا إِلَى الثَّوَابِ

11 الأربعون لمحمد بن أسلم الطوسي

Al-Hasan Al-Basree, may Allaah have mercy upon him, said:

“Every prayer in which the heart is not present is more likely to receive punishment than reward.”
