ʿAli happened to stay behind the Prophet ﷺ and (did not join him) during the battle of Khaibar for he was having eye trouble. Then he said, "How could I remain behind Messenger of Allah ﷺ?" So ʿAli set out following the Prophet ﷺ , When it was the eve of the day in the morning of which Allah helped (the Muslims) to conquer it, Messenger of Allah ﷺ 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 ʿAli whom we did not expect. The people said, "This is ʿAli." Messenger of Allah ﷺ gave him the flag and Allah granted victory under his leadership.  

عَنِ النَّبِيِّ ﷺ فِي خَيْبَرَ وَكَانَ بِهِ رَمَدٌ فَقَالَ أَنَا أَتَخَلَّفُ عَنْ رَسُولِ اللَّهِ ﷺ فَخَرَجَ عَلِيٌّ فَلَحِقَ بِالنَّبِيِّ ﷺ فَلَمَّا كَانَ مَسَاءُ اللَّيْلَةِ الَّتِي فَتَحَهَا اللَّهُ فِي صَبَاحِهَا قَالَ رَسُولُ اللَّهِ ﷺ لأُعْطِيَنَّ الرَّايَةَ أَوْ لَيَأْخُذَنَّ الرَّايَةَ غَدًا رَجُلاً يُحِبُّهُ اللَّهُ وَرَسُولُهُ أَوْ قَالَ يُحِبُّ اللَّهَ وَرَسُولَهُ يَفْتَحُ اللَّهُ عَلَيْهِ فَإِذَا نَحْنُ بِعَلِيٍّ وَمَا نَرْجُوهُ فَقَالُوا هَذَا عَلِيٌّ فَأَعْطَاهُ رَسُولُ اللَّهِ ﷺ فَفَتَحَ اللَّهُ عَلَيْهِ

ʿAli remained behind the Prophet ﷺ during the Ghazwa of Khaibar as he was suffering from eye trouble. He then said, "(How can) I remain behind the Prophet ﷺ ," and followed him. So when he slept on the night of the conquest of Khaibar, the Prophet ﷺ said, "I will give the flag tomorrow, or tomorrow the flag will be taken by a man who is loved by Allah and His Apostle , and (Khaibar) will be conquered through him, (with Allah's help)" While every one of us was hopeful to have the flag, it was said, "Here is ʿAli" and the Prophet ﷺ gave him the flag and Khaibar was conquered through him (with Allah's Help).  

كَانَ عَلِيٌّ ؓ تَخَلَّفَ عَنِ النَّبِيِّ ﷺ فِي خَيْبَرَ وَكَانَ رَمِدًا فَقَالَ أَنَا أَتَخَلَّفُ عَنِ النَّبِيِّ ﷺ فَلَحِقَ فَلَمَّا بِتْنَا اللَّيْلَةَ الَّتِي فُتِحَتْ قَالَ لأُعْطِيَنَّ الرَّايَةَ غَدًا أَوْ لَيَأْخُذَنَّ الرَّايَةَ غَدًا رَجُلٌ يُحِبُّهُ اللَّهُ وَرَسُولُهُ يُفْتَحُ عَلَيْهِ فَنَحْنُ نَرْجُوهَا فَقِيلَ هَذَا عَلِيٌّ فَأَعْطَاهُ فَفُتِحَ عَلَيْهِ  

Is it for me to remain behind Messenger of Allah ﷺ? So he went forth and rejoined Allah's Apostle ﷺ and on the evening of that night (after which) next morning Allah granted victory. Messenger of Allah ﷺ said: I will certainly give this standard to a man whom Allah and His Messenger love. or he said: Who loves Allah or His Messenger and Allah will grant him victory through him, and, lo, we saw 'Ali whom we least expected (to be present on that occasion). They (the Companions) said: Here is 'Ali. Thereupon Messenger of Allah (may peace be upon hin) gave him the standard. Allah granted victory at his hand.  

عَنِ النَّبِيِّ ﷺ فِي خَيْبَرَ وَكَانَ رَمِدًا فَقَالَ أَنَا أَتَخَلَّفُ عَنْ رَسُولِ اللَّهِ ﷺ فَخَرَجَ عَلِيٌّ فَلَحِقَ بِالنَّبِيِّ ﷺ فَلَمَّا كَانَ مَسَاءُ اللَّيْلَةِ الَّتِي فَتَحَهَا اللَّهُ فِي صَبَاحِهَا قَالَ رَسُولُ اللَّهِ ﷺ لأُعْطِيَنَّ الرَّايَةَ أَوْ لَيَأْخُذَنَّ بِالرَّايَةِ غَدًا رَجُلٌ يُحِبُّهُ اللَّهُ وَرَسُولُهُ أَوْ قَالَ يُحِبُّ اللَّهَ وَرَسُولَهُ يَفْتَحُ اللَّهُ عَلَيْهِ فَإِذَا نَحْنُ بِعَلِيٍّ وَمَا نَرْجُوهُ فَقَالُوا هَذَا عَلِيٌّ فَأَعْطَاهُ رَسُولُ اللَّهِ ﷺ الرَّايَةَ فَفَتَحَ اللَّهُ عَلَيْهِ  

"عَنْ سَعْدٍ قَالَ: لَا أَسُبُّ عَلِيّا مَا ذَكرْتُ يَوْمَ خَيْبَرَ حِيْنَ قَالَ رَسُولُ اللهِ ﷺ : لأُعْطِيَنَّ هَذِهِ الرَّايَةَ رَجُلًا يُحِبُّ اللهَ وَرَسُولَهُ وَيُحِبُّهُ اللهُ وَرَسُولُهُ يَفْتَحُ اللهُ عَلَى يَدَيْهِ فَتَطَاوَلُوا لِرَسُولِ اللهِ ﷺ فَقَالَ: أَيْنَ عَلِىٌّ؟ فَقَالُوا: هَوَ أَرْمَدُ، قَالَ: ادْعُوهُ فَدَعَوْهُ فَبَصَقَ فىِ عَيْنِهِ ثُمَّ أَعْطَاهُ الرَّايَةَ فَفَتَحَ اللهُ عَلَيْهِ".
