Ibn Abbas رضي الله عنه on Taqleed (Blind following)..
Shaikh `Abdur-Rahmaan ibn Hasan ibn Muhammad ibn `Abdil-Wahhaab – rahimahullaah – said in “Fathul-Majeed‟ (2/527-530), in explanation of the saying of Ibn `Abbas رضي الله عنه :
“Stones will soon fall upon you from the sky. I say: Allah‟s Messenger (صلى الله عليه وسلم) said, and you say: Abu Bakr and `Umar said!” :
“…This saying from Ibn `Abbas رضي الله عنه was a response to those who said to him: “Abu Bakr and `Umar – radiyallaahu `anhumaa – did not hold joining the `Umrah along with the Hajj (at-tamattu`), and they held that performing Hajj on its own (al-Ifraad) is better‟, or the like of that…
So in summary, it was because of this that Ibn `Abbas رضي الله عنه said, when they countered the Hadeeth with the opinion of Abu Bakr and `Umar -:
“Stones are about to fall upon you from the sky…”
