Salaam I took the brother's word for it that the Shaykh specified 20 years. If he did not say it, I repent from my earlier comment. Astaghfirullah. I agree that no one Shaykh has the claim to 100% truth and that we should be open-minded. However, the amount of conviction with which the Shaykh said that the FSA are terrorists has made me very very wary of taking anything from him that relates to politics. If he teaches me Shafi'i fiqh, then Alhamdulillah - no problem.
