Al-Lalaka'i preserves a report among the karamat of Ali ibn Abi Talib, may Allah be pleased with him, about a man who disputed a hadith or statement in Ali's presence. Ali told him that he appeared to have lied and asked whether he should supplicate to Allah against him if he had lied. The man accepted the challenge, Ali supplicated, and the report says the man became blind before leaving the gathering. Ibn Abi al-Dunya, al-Tabarani, and Ahmad's Fada'il al-Sahaba also preserve forms of the same basic event.
Al-Lalaka'i preserves a report among the accounts of the karamat of Ali ibn Abi Talib, may Allah be pleased with him. The scene begins with a man speaking before Ali and relating or disputing a hadith or statement. The exchange becomes serious when Ali tells him that he appears to have spoken falsely. The man does not withdraw his position, and the report moves directly toward a challenge connected with supplication.
Ali asks the man whether he should call upon Allah against him if he has lied. According to the report, the man accepts and tells Ali to pray. No elaborate formula for the supplication is preserved in the account, so the event is best related without adding words that the source itself does not give. Ali then supplicates to Allah concerning the man's truthfulness.
The extraordinary outcome follows immediately. The report says that the man did not leave the gathering before he lost his sight. In the concise wording preserved by the classical sources, the sequence is close and direct: a disputed statement, Ali's warning that the man had lied, the man's acceptance of the proposed supplication, Ali's prayer, and then the loss of sight before the man departed.
Ibn Abi al-Dunya preserves the same basic incident in Mujabu al-Da'wa. Al-Tabarani records it in al-Mu'jam al-Awsat, and Ahmad's Fada'il al-Sahaba contains a related form in which the setting is connected with al-Rahba. These versions keep the central event recognizable even where some surrounding wording differs: the man disputes or denies what is said before Ali, accepts the challenge of supplication, and is then reported to have become blind.
Al-Lalaka'i's version remains concise. It does not preserve an exact formula for the prayer, a detailed description of how the loss of sight occurred, or a later continuation of the man's story. The account stays with the exchange in the gathering, the challenge concerning the truth of the man's words, Ali's supplication, and the immediate result. Keeping those limits leaves the event in the form in which the classical report presents it.
The story closes at that point. A man maintained his disputed claim before Ali ibn Abi Talib, may Allah be pleased with him; Ali proposed praying against him if he had lied; the man agreed; Ali supplicated; and the report says that before the man left the gathering, his sight was gone. This concise sequence is the remembered karamah in the classical accounts.
