"If you [disbelievers] seek the judgment, the judgment has come to you." Al-Kalbi said: It has reached us that when the polytheists lined up against the Messenger of Allah (may Allah bless him and grant him peace) on the day of Badr, they said: "O Allah, our Lord, whoever among us was more beloved to You and more pleasing to You, grant him victory." So Allah granted victory to His Prophet and said: "If you seek the judgment," meaning: if you seek victory, "the judgment has come to you," meaning the victory; that is, Allah has granted victory to His Prophet. "And if you desist," meaning: from fighting Muhammad, "it is better for you; but if you return, We will return," with defeat for you.
Surah al-Anfal, from verse (20) to verse (25).
﴿إِنْ تَسْتَفْتِحُوا فَقَدْ جَاءَكُمُ الْفَتْحُ﴾ قَالَ الْكَلْبِيُّ:
بَلَغَنَا أَنَّ الْمُشْرِكِينَ لما صافوا رَسُولَ اللَّهِ ﷺ يَوْمَ بَدْرٍ قَالُوا: اللَّهُمَّ رَبَّنَا أَيُّنَا كَانَ أَحَبَّ إِلَيْكَ وَأَرْضَى عِنْدَكَ فَانْصُرْهُ، فَنَصَرَ اللَّهُ نَبِيَّهُ، وَقَالَ: ﴿إِن تستفتحوا﴾ يَعْنِي: تَسْتَنْصِرُوا ﴿فَقَدْ جَاءَكُمُ الْفَتْحُ﴾ النَّصْرُ؛ يَعْنِي: أَنَّ اللَّهَ قَدْ نصر نبيه ﴿وَإِن تنتهوا﴾ يَعْنِي: عَنْ قِتَالِ محمدٍ.
﴿فَهُوَ خَيْرٌ لَكُمْ وَإِنْ تَعُودُوا نَعُدْ﴾ عَلَيْكُم بالهزيمة.
