tahajjud

Q: I want to ask if I can pray Tahajjud when I am unable to pray Zuhr on time and pray it as qaza namaaz.

Q: Can you tell me the tips to wake up for Tahajjud prayer?

Q: I want to know is it compulsory to sleep before performing tahujjud Salaah? If a person is awake till 3 am, can he/she then perform the Salaah? I have heard from many people that it's necessary to sleep before.

Q: Is it permissible to perform twelve rakaats of tahajjud Salaah with one salaam?

Q: It is mentioned in the Hadith that Voluntary Worship is a means of attaining proximity to Allah. Besides the Obligatory and Essential Prayers, the Holy Prophet (Sallallahu Alayhi Wasallam) used to make arrangements for the Voluntary (Nawafil) Prayers too.

1) I want to perform tahajjud namaz daily but when I sleep I don't wake up at the time of tahajjud. So can I just offer eight rakats Voluntary Worship for Allah before going to sleep daily?

2) Is it allowed to perform extra Voluntary Worship any time of a day and any time of night before going to sleep?

Q: What to read in Tahajjud namaaz?

Q: I want to ask that if I fall asleep at night without offering Isha prayer (unintentionally) and then in the middle of night if I wake up, can I offer isha prayer and soon after that tahajjud prayer? Also, do I read tahajjud prayer before witr or after witr (completing isha prayer and then read tahajjud)?

Q: The tahajjud when you pray four rakaats or more, is there a salaam in every two rakaats or when you make an intention to perform eight rakaats you will perform it with a salaam on the last rakaat? or on the eight rakaat?

Q: Allah Ta'ala affords and blesses me with Tahajjud. Some times a few minutes before Fajr, I am sometimes so rushed to perform this ibaadah that I tend to forget the proper way, mindset and recommended acts whilst performing this Salaah. Please give me advice on what my connection, mindset should be like at this mubarak time.

Q: Apart from the Sunnah Salaah viz. Salaat-ud-Duha, Salaat-ut-Tawbah, Salaat-ut-Tasbeeh, are there any other nawaafil Salaah?
