سورة البقرة

Imam Ali (peace be upon him): [Not necessarily] everyone who has an eye sees, and everyone who has an ear hears. So give charity to the wise ones of the ages and the intellects immersed in knowledge [by teaching them], for this is the most excellent of your charities... إِنَّ الَّذِینَ یَکْتُمُونَ ما أَنْزَلْنا مِنَ الْبَیِّناتِ وَ الْهُدی [Indeed, those who conceal what We have revealed of clear proofs and guidance]...

The Prophet (peace be upon him and his family): If people are asked about a knowledge and they conceal it while being aware of it, on the Day of Judgement a bridle of fire will be placed upon their mouths, and the verse أُولَئِکَ یَلْعَنُهُمُ اللهُ وَ یَلْعَنُهُمُ اللَّاعِنُونَ [Those it is whom Allah curses, and those who curse shall curse them too] is revealed concerning them.

Imam Baqir (peace be upon him): A man came to Salman al-Farsi (may Allah have mercy on him) and said: "Narrate a hadith to me." Salman remained silent. He repeated the request. Salman stayed silent. So the man turned back while reciting this verse: إِنَّ الَّذِینَ یَکْتُمُونَ ما أَنْزَلْنا مِنَ الْبَیِّناتِ وَ الْهُدی مِنْ بَعْدِ ما بَیَّنَّاهُ لِلنَّاسِ فِی الْکِتابِ [Indeed, those who conceal what We have revealed of clear proofs and guidance after We have made it clear to the people in the Book]. Then Salman (may Allah have mercy on him) said: "Come forward! If we find a trustworthy person, we surely narrate to him."

Imam Sadiq (peace be upon him): It was revealed concerning Ali (peace be upon him).

Imam Sadiq (peace be upon him): In Tafsir al-Ayyashi it is narrated: I said: "Explain to me the word of Allah where He says: إِنَّ الَّذِینَ یَکْتُمُونَ ما أَنْزَلْنا مِنَ الْبَیِّناتِ وَ الْهُدی مِنْ بَعْدِ ما بَیَّنَّاهُ لِلنَّاسِ فِی الْکِتابِ [Surely those who conceal the clear proofs and the guidance that We revealed after We made it clear in the Book for men]." He said: "What is meant by [the clear proofs and the guidance] is us, and Allah is our helper; [it is as though it has become a custom that] whenever the station of imamate reaches one of us, [the people] do not turn to him and do not go towards him until the next [Imam] comes and explains it to the people."

Imam al-Askari (peace be upon him): "al-Bayyinat" refers to the qualities of Muhammad (peace be upon him and his family) and Ali (peace be upon him), and the guidance which We made clear for the people in the Book. Allah said: "Those guidances which We sent down, which are the signs of the excellence and station of the Prophet (peace be upon him and his family) that We made manifest to the people; such as the clouds which cast shade over the Messenger of Allah (peace be upon him and his family) on his journeys, and the bitter and salty waters which, when the saliva of his mouth reached them, became sweet and pleasant, and the trees whose fruits would hang down when he sat beneath them, and the diseases which, when he passed his hand over the afflicted person's head, would all vanish, and the afflictions which were destroyed when his saliva reached them; and like the signs which He manifested concerning Ali (peace be upon him) — among those signs is the submission of the mountains, rocks and trees, while they called him the wali of Allah and the successor of the Messenger of Allah (peace be upon him and his family); and also the deadly poisons which, when the one consuming them uttered Ali's (peace be upon him) name over them, did not harm him; and great deeds such as uprooting hills and mountains and hurling them, which were easy for him [the one who invoked Ali's (peace be upon him) name], and he would tear those mountains loose and hurl them like small pebbles; and diseases which vanished by his supplication, and afflictions and calamities which, by the supplication of his eminence, were rendered safe, free of defect and harmless; and the rest of the virtues that are exclusive to him — and this is among the guidance which Allah has explained in His Book for the people."

Imam al-Askari (peace be upon him): In cursing there are several situations. Among them is that the cursers curse them, and there is no one — whether this curse be rightly or wrongly directed at him — but he says: "May Allah's curse be upon those who conceal the truth and upon the oppressors!" Indeed the oppressor and the concealer of the truth also says: May Allah's curse be upon the oppressors and the concealers of the truth. So they are cursed both by the cursers and by themselves, even though they themselves are among them. When these two groups grow exasperated with each other and curse one another, the two curses ascend and seek permission from their Lord to return to the one against whom they were sent. (These two "curses" ask Allah that they may take effect upon the one intended, namely the accursed ones.) So Allah the Mighty and Majestic says to the angels: "Look — if the curser, and not the one cursed, is deserving of the curse, then send down both curses upon the curser; and if the one cursed, and not the curser, is deserving of the curse, then send down both curses upon the one cursed; and if both of them are deserving of the curse, then direct the curse of one upon the other and the curse of the other upon the one; and if neither of them is deserving of it, because of their faith, and only restlessness and lack of forbearance drove the two of them to cursing, then direct both curses toward the Jews and those who concealed the noble qualities and attributes of Muhammad (peace be upon him and his family) and [the mention of] Ali (peace be upon him) and his description, and toward the Nasibis who, out of enmity, concealed the excellence of Ali (peace be upon him) and withheld him from it."

Imam Sadiq (peace be upon him): [regarding] أُولَئِکَ یَلْعَنُهُمُ اللّٰهُ وَ یَلْعَنُهُمُ اللَّاعِنُونَ [Those, Allah shall curse them and the cursers shall curse them] — the meaning of "them" (the cursers) is us.

Imam al-Askari (peace be upon him): al-Ihtijaj, with its chain from Imam al-Askari (peace be upon him), has reported: It was said to Amir al-Mu'minin (peace be upon him): "After the Imams of guidance and the lamps in the darkness, who are the best of creatures?" He said: "The righteous scholars." They asked again: "After Iblis, Pharaoh, Nimrod, and those who bear your names and titles, seize your places and rule in your lands, who are the worst of creatures?" He said: "The corrupt scholars; they are the ones who make manifest what is false and conceal the truths. And concerning them Allah the Mighty and Majestic has said: أُولَئِکَ یَلْعَنُهُمُ اللّٰهُ وَ یَلْعَنُهُمُ اللَّاعِنُونَ [these it is whom Allah shall curse, and those who curse shall curse them]."

Ali ibn Ibrahim (may Allah have mercy on him): [Even] all the jinn and humans who have been cursed by Allah curse them (that is, the disbelievers).
