Witr and Nawaafil

Q: After praying Fajr, can we offer nafl or do we have to wait after sunrise?

Q: There are 2 virtues to ishraaq. One is the reward for hajj and umrah, the second is that one's day will be made easy. To get both these rewards, should 4 raka'aats be read in one go, or each set of 2 raka'aats separately?

Q: If I join an Eshaa Salaah behind an imaam with the intention of nafl, after missing the first 2 rakaats. Will I have to make the missed rakaats after the imaam terminates the salaah? Or will the 2 rakaats of nafl be valid and I may end the salaah with the imaam?

Q: What is the maximum amount of rakaats one can perform in tahajjud with making salaam in the end? I heard that the most is eight rakaats, but can a person perform more than eight rakaats with making salaam at the end?

Q: Please explain the manner of Rasulullah (sallallahu alaihi wasallam)'s tahajjud and the duas he would recite upon awakening for tahajjud.

Q: When I perform my Tahajjud prayer, I have a pain in my head and my brain stops working properly.

During Tahajjud prayer I feel that something is shaking in my head. Please give a solution for this.

Q: Can Dua-e-istikhaara be performed for trivial decisions, or should it be reserved for major life choices?

Q: I have some questions regarding tahajjud.

1. How long before fajr does the time for tahajjud end?

2. What is the sunnah method for performing tahajjud?

3. How do I pray tahajjud during haidh?

Q: My question is regarding istikhara. I performed istikhara regarding a person and recently found out something that would be counted as an obstacle/barrier between me and this person. So I understand that Allah is showing me there is no good in this matter and so my question is that does this mean that this person will never be good for me or perhaps that this person is not good for me in this moment. And I am transgressing against Allah by hoping that we could perhaps reunite, since I genuinely believe this person is good for my deen and aakhirah and I am saying that based on me ignoring my desires and thinking hard whether or not this perosn will help me get closer to Allah.

Q: The first Adhaan for Jumuah Salaah in both the Haramain Sharifain is given well before Zawaal sets in. Can one perform the Four Sunnats of Jumuah after the first Adhaan is given i.e. before the time of Zawaal?

The second Adhaan is given exactly when the Dhuhr time sets in and the Khutbah commences immediately thereafter. There is no time to perform the sunnats after the second Adhaan as the khutbah commences immediately, and if one stands up to perform his sunnats, he will be performing his sunnats while the Khutbah is being delivered. Should one rather perform these four sunnats after completing the Jumuah Salaah?
