Mashallah may God accept your Umrah and I hope you had a good time.
Ok I think I understand what you saw now. Yes many Shia after they have prayed their sunnah and wajib Salaat will start offering extra Salats. These may be Qada' Salaats either for themselves or a deceased parent. These also may be Nawafil Salats offered for someone who themselves couldn't make it to Umra or Hajj.
This is NOT haram as far as I know since I have done it myself. Muslimah can you provide a fatwa of one of your ulema or a hadith in which after Fajr Zzuhr or Maghrib praying any sort of Salat is haram? Also I observed in Mecca that Salatul Janaza was offered straight after Fajr or Zuhr or Asr so I dont think offering Salat for whatever reason after Fajr or Zuhr or Asr can be considered Haram.
As for those who pray on their own I don't know what their problem is.
Quote:just like many others who for instance keep touching gates of Ka`ba or gates of Masjed Nabawy, or even here in Egypt go and pray and touch Maqam of Hussain, Sayeda Zaynab ..etc.
Touching the gates of Ka'aba or Masjid Nabawy or Maqam Hussein or Sayyeda Zainab is NOT haram.
