[Pooya/Ali Commentary 25:28] Do not make friends with any one who openly or secretly has opposed the commands of Allah and the Holy Prophet. The thoroughly purified Ahl ul Bayt are alone the best medium to reach the nearness of the absolute pure. Be their friends and followers. A warning has been given in these verses not to choose or accept any one, other than the thoroughly purified, as the guide-leader (Imam), particularly those who on account of their spiritual impurity openly defied the commands of Allah and the Holy Prophet regarding the wilayah and imamah of Ali ibn abi Talib and the Imams in his progeny through Bibi Fatimah Zahra. Please refer to hadith al thaqalayn under "Essentials: For the readers of the Holy Quran"; commentary of al Ma-idah : 5 and 67; Ali Imran : 61; Ahzab : 33. The impurity of evil in the opponents of the Ahl ul Bayt always betrays people in time of need.
