[Machine] Opening of Khaybar, so that Allah may forgive you for what preceded of your sin and what follows. (Surah Al-Fath, 48:2) So they said, "O Messenger of Allah, congratulations to you! But what is for us?" So Allah revealed, "So that He may admit the believing men and believing women to gardens beneath which rivers flow." (Surah Al-Fath, 48:5)
فِي قَوْلِهِ ﷻ {إِنَّا فَتَحْنَا لَكَ فَتْحًا مُبِينًا} [الفتح 1] قَالَ فَتْحُ خَيْبَرَ {لِيَغْفِرَ لَكَ اللَّهُ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ} [الفتح 2] فَقَالُوا يَا رَسُولَ اللَّهِ هَنِيئًا لَكَ فَمَا لَنَا؟ فَأَنْزَلَ اللَّهُ ﷻ {لِيُدْخِلَ الْمُؤْمِنِينَ وَالْمُؤْمِنَاتِ جَنَّاتٍ تَجْرِي مِنْ تَحْتِهَا الْأَنْهَارُ} [الفتح 5]
