[Machine] The first person to embrace Islam with the Messenger of Allah ﷺ , was Ali ibn Abi Talib.  

«أَوَّلُ مَنْ أَسْلَمَ مَعَ رَسُولِ اللهِ ﷺ عَلِيُّ بْنُ أَبِي طَالِبٍ»  

[Machine] "The first person to embrace Islam was Ali."  

«أَوَّلُ مَنْ أَسْلَمَ عَلِيٌّ»  

[Machine] I heard Zaid bin Arqam saying, "The first person to pray with the Messenger of Allah ﷺ was Ali." And he said in another place, "Ali was the first to convert to Islam."  

سَمِعْتُ زَيْدَ بْنَ أَرْقَمَ يَقُولُ «أَوَّلُ مَنْ صَلَّى مَعَ رَسُولِ اللهِ ﷺ عَلِيٌّ» وَقَالَ فِي مَوْضِعٍ آخَرَ «أَسْلَمَ عَلِيٌّ»  

[Machine] On his right was a young man. He did not stay long before a woman came and stood behind them. The young man bowed down in prayer, and the boy and the woman followed suit. The young man raised his head, and the boy and the woman also raised their heads. Then the young man prostrated, and the boy and the woman prostrated with him. I said, "O Abbas, this is a great matter." He asked me, "What is the great matter?" I said, "Do you know who this young man is?" I said no. He said, "This is Muhammad ibn Abdullah ibn Abdul-Muttalib. He is my nephew. And do you know who this boy is?" I said no. He said, "This is Ali ibn Abi Talib ibn Abdul-Muttalib. He is my nephew. And do you know who this woman is who is behind them?" I said no. He said, "This is Khadijah bint Khuwaylid, the wife of my nephew." This is what he informed me, "That your Lord, the Lord of the heavens and the earth, has commanded him with this religion that he is upon. By Allah, there is no one on the face of the earth upon this religion except for these three."  

عَنْ يَمِينِهِ فَلَمْ يَلْبَثْ حَتَّى جَاءَتِ امْرَأَةٌ فَقَامَتْ خَلْفَهُمَا فَرَكَعَ الشَّابُّ فَرَكَعَ الْغُلَامُ وَالْمَرْأَةُ فَرَفَعَ الشَّابُّ فَرَفَعَ الْغُلَامُ وَالْمَرْأَةُ فَخَرَّ الشَّابُّ سَاجِدًا فَسَجَدَا مَعَهُ فَقُلْتُ يَا عَبَّاسُ «أَمْرٌ عَظِيمٌ» فَقَالَ لِي أَمْرٌ عَظِيمٌ؟ فَقَالَ «أَتَدْرِي مَنْ هَذَا الشَّابُّ؟» فَقُلْتُ لَا فَقَالَ هَذَا مُحَمَّدُ بْنُ عَبْدِ اللهِ بْنِ عَبْدِ الْمُطَّلِبِ هَذَا ابْنُ أَخِي وَقَالَ «تَدْرِي مَنْ هَذَا الْغُلَامُ؟» فَقُلْتُ لَا قَالَ عَلِيُّ بْنُ أَبِي طَالِبِ بْنِ عَبْدِ الْمُطَّلِبِ هَذَا ابْنُ أَخِي «هَلْ تَدْرِي مَنْ هَذِهِ الْمَرْأَةُ الَّتِي خَلْفَهُمَا؟» قُلْتُ لَا قَالَ «هَذِهِ خَدِيجَةُ ابْنَةُ خُوَيْلِدٍ زَوْجَةُ ابْنِ أَخِي» هَذَا حَدَّثَنِي «أَنَّ رَبَّكَ رَبُّ السَّموَاتِ وَالْأَرْضِ أَمَرَهُ بِهَذَا الدِّينِ الَّذِي هُوَ عَلَيْهِ وَلَا وَاللهِ مَا عَلَى ظَهْرِ الْأَرْضِ كُلِّهَا أَحَدٌ عَلَى هَذَا الدِّينِ غَيْرُ هَؤُلَاءِ الثَّلَاثَةِ»  

"'Ali said: 'I am the slave of Allah and the brother of His Messenger. I am the greatest teller of the truth (Siddiq Akbar), and no one will say this after me except a liar. I prayed seven years before the people." (Using translation from Ibn Mājah 120)  

قَالَ عَلِيٌّ «أَنَا عَبْدُ اللهِ وَأَخُو رَسُولِهِ ﷺ وَأَنَا الصِّدِّيقُ الْأَكْبَرُ لَا يَقُولُهَا بَعْدِي إِلَّا كَاذِبٌ صَلَّيْتُ قَبْلَ النَّاسِ بِسَبْعِ سِنِينَ»
