Sahih Bukhari 3702

حَدَّثَنَا قُتَيْبَةُ ، حَدَّثَنَا حَاتِمٌ ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ ، عَنْ سَلَمَةَ ، قَالَ : كَانَ عَلِيٌّ قَدْ تَخَلَّفَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي خَيْبَرَ وَكَانَ بِهِ رَمَدٌ ، فَقَالَ : أَنَا أَتَخَلَّفُ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ , فَخَرَجَ عَلِيٌّ فَلَحِقَ بِالنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَلَمَّا كَانَ مَسَاءُ اللَّيْلَةِ الَّتِي فَتَحَهَا اللَّهُ فِي صَبَاحِهَا ، قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : لَأُعْطِيَنَّ الرَّايَةَ أَوْ لَيَأْخُذَنَّ الرَّايَةَ غَدًا رَجُلًا يُحِبُّهُ اللَّهُ وَرَسُولُهُ , أَوْ قَالَ : يُحِبُّ اللَّهَ وَرَسُولَهُ يَفْتَحُ اللَّهُ عَلَيْهِ , فَإِذَا نَحْنُ بِعَلِيٍّ وَمَا نَرْجُوهُ ، فَقَالُوا : هَذَا عَلِيٌّ فَأَعْطَاهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الرَّايَةَ فَفَتَحَ اللَّهُ عَلَيْهِ .

Narrated Salama: `Ali happened to stay behind the Prophet and (did not join him) during the battle of Khaibar for he was having eye trouble. Then he said, How could I remain behind Allah's Apostle? So `Ali set out following the Prophet , When it was the eve of the day in the morning of which Allah helped (the Muslims) to conquer it, Allah's Apostle said, I will give the flag (to a man), or tomorrow a man whom Allah and His Apostle love will take the flag, or said, A man who loves Allah and His Apostle; and Allah will grant victory under his leadership. Suddenly came `Ali whom we did not expect. The people said, This is `Ali. Allah's Apostle gave him the flag and Allah granted victory under his leadership.
