When this verse was revealed, "And whether you disclose what is within yourselves or conceal it, Allah will bring you to account for it" [Baqarah 2:284], something entered their hearts from it which had never entered their hearts from anything before.The Messenger of Allah ﷺ said, "Say, 'We hear and we obey and we submit.'"So Allah cast faith into their hearts, and Allah the Exalted revealed, "Allah does not burden a soul beyond what it can bear. It will have what it has earned, and against it what it has acquired. Our Lord, do not take us to task if we forget or err" [Baqarah 2:286].He said, "I have done so.""Our Lord, and do not lay upon us a burden like that which You laid upon those before us."He said, "I have done so.""And pardon us and have mercy upon us. You are our Protector" [Baqarah 2:286].He said, "I have done so."
لما نزلت هذه الآية {وإن تبدوا ما في أنفسكم أو تخفوه يحاسبكم به الله} [سورة البقرة: ٢٨٤] قال: دخل قلوبهم منها شيء لم يدخل قلوبهم من شيء، فقال رسول الله ﷺ: قولوا: سمعنا وأطعنا وسلمنا قال: فألقى الله الإيمان في قلوبهم، فأنزل الله تعالى: {لا يكلف الله نفسا إلا وسعها لها ما كسبت وعليها ما اكتسبت ربنا لا تؤاخذنا إن نسينا أو أخطأنا}. قال: قد فعلت. {ربنا ولا تحمل علينا إصرا كما حملته على الذين من قبلنا}. قال: قد فعلت. {وأغفر لنا وارحمنا أنت مولنا} [سورة البقرة: ٢٨٦] قال: قد فعلت.
Muslim narrated it in the Book of Faith (126) through several routes from Waki, from Sufyan, from Adam bin Sulayman, the freed slave of Khalid, who said, I heard Saeed bin Jubayr narrating from Ibn Abbas, and he related the hadith.His statement, "something entered their hearts because of it," with "minha" (because of it) referring to this verse, and "shay" (something) in the nominative case being the subject of "entered," meaning that something great of grief entered because of this verse. His statement, "nothing like it had ever entered their hearts," this clause is a description of it, meaning that nothing like this had ever entered their hearts before.
