ishraaq

Q: Salatul ishraq is the start of salat duha? Like if I pray 2 rakat after 20 mins of sunrise, so it will be considered as both, chasht and ishraq prayer?

Q:

1. I wanted to ask you that if salat al tasbeeh was proven in hadith or not?

2. Is salat al ishraq valid even if one sleeps in between fajr and salat al ishraq?

3. And how many rakats should be offered?

Q: How to work out the end time of Ishraaq?

Q: What is the end time of the (a) Israaq prayer and (b) Duha prayer? I already know their start times and preferred times, but would like to know their end times please.

Q: What is the definition of sunrise/shurooq? When the sun slightly appears on the horizon or when the sun completely is visible on the horizon?

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