سورة الأعراف

Imam Sadiq (peace be upon him): Ammar Sabati said: "I asked Imam Sadiq (peace be upon him): 'Does the Imam know the unseen?' He said: 'No, but whenever he wishes to know something, Allah teaches it to him.'"

Imam Kazim (peace be upon him): Ibn Mughira said: I and Yahya ibn Abdullah ibn Hasan were in the presence of Imam Kazim (peace be upon him). Yahya said to His Eminence: "May I be your ransom! A group believes that you know the unseen?" He said: "Subhan-Allah, place your hand on my head — see, by Allah, every hair on my head and body stood on end!" Then he said: "No! By Allah! What we know we have only inherited from the Messenger of Allah (peace be upon him and his family)."

Ali ibn Ibrahim (may Allah have mercy on him): وَ لَوْ کُنْتُ أَعْلَمُ الْغَیْبَ لاَسْتَکْثَرْتُ مِنَ الخَیْرِ وَ ما مَسَّنِیَ السُّوءُ [And had I known the unseen I would have had much of good and no evil would have touched me] — that is, I would have chosen health and safety for myself.

Imam Sadiq (peace be upon him) said to one of his companions: "When you want to be cupped and the blood comes out from your cupping site, before you finish and while the blood is flowing, say: بِسْمِ اللهِ الرَّحْمنِ الرَّحِیم [In the Name of Allah, the All-Merciful, the All-Compassionate]; I take refuge in Allah the Generous in this cupping of mine from the evil eye in the blood and from every evil." Then he said: "O so-and-so, do you not know that when you say this, you have indeed gathered all things together, for Allah the Blessed and Exalted says: وَ لَوْ کُنْتُ أَعْلَمُ الْغَیْبَ لاَسْتَکْثَرْتُ مِنَ الخَیْرِ [And had I known the unseen, I would have multiplied the good for myself]."

Imam Sadiq (peace be upon him): [Regarding] the verse: وَ لَوْ کُنْتُ أَعْلَمُ الْغَیْبَ لَاسْتَکْثَرْتُ مِنَ الخَیْرِ وَ ما مَسَّنِیَ السُّوءُ [And had I known the unseen, I would have multiplied the good for myself, and no evil would have touched me]; al-su' (evil) means poverty.
