[Pooya/Ali Commentary 73:2] Midnight and after midnight prayers and contemplation are called tahajjud. In the beginning the believers used to cease sleeping and pray tahajjud throughout the night. They are now advised to pray only for a small part of the night, or increase the duration of prayers a little more if the prayer desires so. The words of the Quran must not be read hastily, merely to complete a ritual. They must be pronounced with ease and correctness, knowing the true meaning and interpretation of every word. Aqa Mahdi Puya says: It means the Quran was with the Holy Prophet. He knew every word of it. Here the people are advised through him to recite it in slow and measured tones.
