Surah Yaseen and Surah Al-Waqi'ah both emphasize the reality of the Hereafter and the importance of preparing for it through faith and righteous deeds. While Surah Yaseen reminds us of the signs of Allah and the resurrection, Surah Al-Waqi'ah details the outcomes awaiting different groups on the Day of Judgment. For deeper reflection on that Day, you can also read سورة الزلزلة مكتوبة, which powerfully illustrates the earth’s final quake and the accountability that follows.
