Witr and Nawaafil

Q: If one misses the sunnat salaah of fajr, then should he join the Imaam in jamaat and leave out the sunnats?

Q: I have two questions I want you to help me with. May Allah Ta'ala grant you the ability.

1. I want to know how to perform istighfaar Salaah with full details.

2. And also, are there any particular Surahs to be recited or any particular prayers to be performed for one to get married soon? They have been searching for a good groom for me for the past one year but nothing is become finalized and is failing for some reason or other. I don't know why but Allah knows best.

Q: How do you make the niyyat and pray the prayer of repentance. I have heard you make wudhu and pray two nafil. But what do you say in the niyyat exactly and is there anything special you say after the namaaz? Also can you make wudu for Esha namaaz, pray the repentance namaaz and then pray isha right after with the same wudhu?

Q: Can you please advise the correct way to perform Tahajjud salah (night prayer)? Is it permissible to pray it after the Isha prayer? Is it permissible to wake up at a certain time where I can pray my Tahajud and an hour later I can pray Fajar? Please advise the best way to focus in namaz, due to some of the stressful conditions I am going through, those thoughts come and go in my mind during Salah. How can I stop that or focus more on salaah?

Q: I know that it is preferable to perform Sunnats and Nawaafil of Maghrib, Esha etc at home but if that relative's home has pictures of animate objects in the form of children's books & toys, is it then better to perform the Sunnats and Nawaafil in the Masjid as my understanding is no angel apart from Malikul Maut enters that house?

Q: Is it right that we should recite At-tahiyat and durood after the second rakaat of sunnat ghair muaqqadah?

Q: What is the difference in the way of offering of Sunnat-e-Muaqqadah and Sunnat Ghair Muaqqadah Salaah?

Q:

1. How many rakaats must be read?

2. Is it Sunnat, Fard, Nafl etc?

Q: Are there two Witr namaaz's per day? ie. 1. Esha - 3 rakaats Witr Wajib 2. Tahajjud - 2 rakaat followed by 1 rakaat Witr? Should both be read every night or are they the same and only one should be read?

Q: I want to know how should one pray haajat nafil Salaah? How many rakaats should one pray and what are the Surahs to be recited?
