Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
quran:30:43 –

So direct your face toward the correct religion before a Day comes from Allah of which there is no repelling. That Day, they will be divided.  

So set your purpose for the upright religion, the religion of Islam, before there comes the inevitable day from God, namely, the Day of Resurrection. On that day they shall be sundered (yassadda‘ūna: the original tā’ ˹yatasadda‘ūna˺ has been assimilated with the sād), that is, they will be split ˹into separate groups˺ after the Reckoning ˹destined˺ for Paradise or the Fire.
القرآن:٣٠:٤٣ –

فَأَقِمْ وَجْهَكَ لِلدِّينِ الْقَيِّمِ مِنْ قَبْلِ أَنْ يَأْتِيَ يَوْمٌ لَا مَرَدَّ لَهُ مِنَ اللَّهِ ۖ يَوْمَئِذٍ يَصَّدَّعُونَ  

{فأقم وجهك للدين القيِّم} دين الإسلام {من قبل أن يأتي يوم لا مردَّ له من الله} هو يوم القيامة {يومئذ يصَّدَّعون} فيه إدغام التاء في الأصل في الصاد: يتفرقون بعد الحساب إلى الجنة والنار.
