Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Sinan from Muhammad ibn Hakim from those whom has mentioned (in his book) from Abu ‘Abdillah (a.s.) who has said the following: “Amir al-Mu’minin, Ali ibn abu Talib (a.s.) has said, ‘What is beneficial on the Day of Judgment is not small (insignificant) and nor what is harmful for one on the Day of Judgment is small (insignificant).

About whatever Allah, the Most Majestic, the Most Holy, has informed, you must be like one who has eye-witnessed them.’” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (11/367))
