Tahajjud

Voluntary night prayer in Islam Tahajjud, (Arabic: تَهَجُّد) also known as the "night prayer" or "Qiyam-u-lail", as well as "Namaaz-e-Shab" (نماز شب) in Persian (later borrowed into Urdu and Hindi) is a voluntary prayer performed by followers of Islam. It is not one of the five obligatory prayers required of all Muslims, although the Islamic prophet Muhammad was recorded as performing the tahajjud prayer regularly himself and encouraging his companions. The Tahajjud prayer is usually performed in the last third of the night, when Allāh descends to the lowest of the heavens to answer supplications. Evidence in Next to these Qur'anic verses, there also exist a number of hadiths (narrated and confirmed traditions from Muhammad) that reinforce the importance of Tahajjud Prayer. In various hadiths, it has been mentioned as Qiyamul Sabah (standing of morning), Salatul Sabah (prayer of morning) and Tahajjud. Recommended time To perform tahajjud signifies the act of rising from sleep during the night and then praying. Tahajjud may be performed before or after imsak (imsak is when the fasting starts) but before the obligatory Fajr prayer. Commenting on this subject, Ibn Hajar
