quran:3:9 –

Our Lord, surely You will gather the people for a Day about which there is no doubt. Indeed, Allah does not fail in His promise."  

Our Lord, You shall gather mankind for a day, that is, on a day, of which there is no doubt, no uncertainty, that is, the Day of Resurrection, when You will requite them for their deeds as You had promised; verily God will not fail the tryst, His promise of the Upraising: there is a shift of address here from the second ˹to the third˺ person and these ˹last words˺ could constitute God’s speech. The purpose of their supplication in this way is to show that their concern is with the matter of the Hereafter, and for this reason they ask ˹God˺ for adherence to the path of guidance, in order to attain its reward. The two Shaykhs ˹Bukhārī and Muslim˺ reported that ‘Ā’isha, may God be pleased with her, said, ‘The Messenger of God (s) recited this verse: It is He Who revealed to you the Book, wherein are verses clear ˹to the end of˺ the verse, and said, “When you see those pursuing the allegorical parts, ˹know that˺ these are the ones God refers to ˹in this verse˺, so beware of them” ’. Al-Tabarānī reported in his al-Kabīr that Abū Mūsā al-Ash‘arī heard the Prophet (s) say, ‘I fear nothing for my community except three faults’, and he mentioned that one of these would be when the Book is opened in front of them, and the believer will desire to interpret it, and yet none knows its interpretation, save God; and those firmly rooted in knowledge say, ‘We believe in it, all is from our Lord; yet none remembers but people of pith’ ˹Q. 3:7˺ ˹end of the˺ hadīth.
القرآن:٣:٩ –

رَبَّنَا إِنَّكَ جَامِعُ النَّاسِ لِيَوْمٍ لَا رَيْبَ فِيهِ ۚ إِنَّ اللَّهَ لَا يُخْلِفُ الْمِيعَادَ  

يا {ربنا إنك جامع الناس} تجمعهم {ليوم} أي في يوم {لا ريب} لا شك {فيه} هو يوم القيامة فتجازيهم بأعمالهم كما وعدت بذلك {إن الله لا يخلف الميعاد} موعده بالبعث فيه التفات عن الخطاب ويحتمل أن يكون من كلامه تعالى والغرض من الدعاء بذلك بيان أن همهم أمر الآخرة ولذلك سألوا الثبات على الهداية لينالوا ثوابها روى الشيخان عن عائشة ؓ قالت: (تلا رسول الله ﷺ هذه الآية هو الذي أنزل عليك الكتاب منه آيات محكمات إلى آخرها وقال: فإذا رأيت الذين يتبعون ما تشابه منه فأولئك الذين سمى الله فاحذروهم) وروى الطبراني في الكبير عن أبي موسى الأشعري أنه سمع النبي ﷺ يقول: (ما أخاف على أمتي إلا ثلاث خلال وذكر منها أن يفتح لهم الكتاب فيأخذه المؤمن يبتغي تأويله وليس يعلم تأويله إلا الله والراسخون في العلم يقولون آمنا به كل من عند ربنا وما يذكر إلا أولو الألباب) الحديث.
