On the day of Badr, the Messenger of Allah ﷺ looked at the polytheists, who numbered a thousand, while his companions were three hundred and nineteen men. The Prophet of Allah faced the qiblah, then stretched out his hands and began calling upon his Lord, "O Allah, fulfill for me what You have promised me. O Allah, grant me what You have promised me. O Allah, if You destroy this band of the people of Islam, You will not be worshipped on earth."Then Allah reinforced him with the angels. The hadith continues.
لما كان يوم بدر نظر رسول الله ﷺ إلى المشركين وهم ألف، وأصحابه ثلاثمئة وتسعة عشر رجلا، فاستقبل نبي الله القبلة، ثم مد يديه فجعل يهتف بربه: اللهم أنجز لي ما وعدتني، اللهم آت ما وعدتني، اللهم إن تهلك هذه العصابة من أهل الإسلام لا تعبد في الأرض… فأمده الله بالملائكة. الحديث.
Muslim narrated it in jihad (1763), from Hannad bin Sari, from Ibn Mubarak, from Ikrima bin Ammar, from Simak Hanafi, who said, I heard Ibn Abbas say, Umar bin Khattab narrated to me, and he mentioned it.
