Answered by Shaykh Faraz Rabbani
Duas for the Night.Thank you and may Allah bless you for clarifying that witr prayer should be the last prayer of the night. One who is used to getting up for Tahajjud prayer should say Witr at that time. Please clarify if it should be said before Tahajjud or after Tahajjud.
Any dhikr or dua.
If you learn the duas of the Beloved of Allah (peace and blessings be upon him, his family, companions and followers), then that is even more beloved to Allah.
Every serious Muslim should have a good book of Prophetic invocations that they operationalize in their daily life, to illuminate it with the light that is the guidance of the Prophet (Allah bless him & give him peace).
