Reciting the “daal” in “wa lad-daaalleen” for less than 6 seconds

Q: I heard that when reading Surah Fatihah, you need to make the sound of the “dal” in “wa lad-daaalleen” longer, till 6 seconds. However, it is difficult for me to count how many seconds and often I finish it in 3 second or so. Is my prayer valid even if I do it deliberately because I can’t count seconds when reciting?

Masturbating in the state of ihraam

Q: A few years ago, I went for Hajj. May Allah Ta'ala forgive me, at that time (I can't remember if it was before or after Arafaat), I committed the terrible sin of masturbation. May Allah Ta'ala forgive me. What is the penalty for this? Also, does that act break ghusl? I doubt I made a ghusl after I committed that act. May Allah Ta'ala forgive me.
