Saya coba browsing ke 2 nara sumber saya, yakni :
http://www.usc.edu/dept/MSA/fundamentals/hadithsunnah/bukhari/015.sbt.html
dan http://hadith.al-islam.com/Display/Display.asp?Doc=0&Rec=1547
Saya copikan dari Hadits Shahih Imam Bukhari sbb.:
Volume 2, Book 15, Number 86:
Narrated Ibn Abbas:
The Prophet said, “No good deeds done on other days are superior to those done on these (first ten days of Dhul Hijja).” Then some companions of the Prophet said, “Not even Jihad?” He replied, “Not even Jihad, except that of a man who does it by putting himself and his property in danger (for Allah’s sake) and does not return with any of those things.”
Adapun yg di Syarahnya, yakni Fathul Bari bi syarhih Shahih Bukhari, disebutkan bahwa hadits2 senada dg hadits di atas, banyak ditemukan di berbagai riwayat, misalnya Imam Ahmad, Imam Abu Dawud, dsb. Adapun istilah Tarwiyah itu hanya dikhususkan tanggal 8 sbgmn istilah Arafah dikhususkan tgl 9.
Demikian, mudah2an bermanfaat.
