What's his name? His name is 'Abdullāh ibn 'Uthmān ibn 'Āmir At-Taymī. Abū Bakr is his kunyah. 2. Why was he known as Aṣ-Ṣiddīq? As soon as he heard about the Prophet's message he immediately embraced Islām without any hesitation. Abud-Dardā' reported that the prophet ﷺ said: ((إِنَّ اللهَ بَعَثَنِي إِلَيْكُمْ فَقُلْتُمْ كَذَبْتَ‏.‏ وَقَالَ أَبُو بَكْرٍ صَدَقَ‏.‏ وَوَاسَانِي بِنَفْسِهِ وَمَالِهِ)) "Allāh sent me (as a Prophet) to you (people) but you said (to me), 'You are telling a lie,' while Abū Bakr said, 'He has said the truth,' and consoled me with himself and his money." [Bukhāri] 3. There are numerous evidences showing the excellence and superiority of Abū Bakr; here are some: (1) The Prophet ﷺ said: ((لو كنتُ متخذا من أمتي خليلا لاتخاذت أبا بكر خليلا)) "If I were to have taken anyone of my Ummah as a close friend, I would have surely taken Abū Bakr as a close friend." [Bukhāri & Muslim] (2) 'Amr ibnul 'Ās said: I asked the Prophet ﷺ: Who is the most beloved person to you? He said: 'A'ishah. I said: Among the men? He said: Her father (i.e. Abū Bakr). I said: Who next? He said: 'Umar. He then named some other men. [Bukhāri & Muslim] (3) The prophet ﷺ gave him glad tidings of Jannah. Abū Mūsā Al-Ash'arī reported that he was once in the company of the Prophet (ﷺ) in one of the gardens of Madīnah when a man came and asked permission to enter. The Prophet (ﷺ) said, ((افْتَحْ لَهُ وَبَشِّرْهُ بِالْجَنَّةِ)) "Open the gate for him and give him the glad tidings of entering Paradise." I went, and behold! It was Abū Bakr. So I opened the gate for him and informed him of the glad tidings of entering Paradise..." [Bukhāri & Muslim] (4) Abū Bakr's companionship is established in the Qur'ān; see [Sūrat At-Tawbah 40] (5) 'A'ishah reported that: during his (last) illness, the Messenger (ﷺ) said to me: ((ادْعِي لِي أَبَا بَكْرٍ وَأَخَاكِ حَتَّى أَكْتُبَ كِتَابًا فَإِنِّي أَخَافُ أَنْ يَتَمَنَّى مُتَمَنٍّ وَيَقُولَ قَائِلٌ أَنَا أَوْلَى.‏ وَيَأْبَى اللهُ وَالْمُؤْمِنُونَ إِلاَّ أَبَا بَكْرٍ)) "Call Abū Bakr and your brother for me, so that I may write a will, for I fear that someone else might be desirous (of succeeding) and that some claimant may say: I have better claim to it, whereas Allāh and the Faithful do not substantiate the claim of anyone but that of Abū Bakr." [Muslim] (6) Abdullāh ibn 'Umar, may Allāh be pleased with him, said: كنا نخيِّر بين الناس في زمن النبي ﷺ، فنخيِّر أبا بكر، ثم عمر بن الخطاب، ثم عثمان رضي الله تعالى عنهم. "We used to compare the people as to who was better during the lifetime of Allāh's Messenger (ﷺ), and we used to regard Abū Bakr as the best, then 'Umar, and then Uthmān." [Bukhāri] (7) Muḥammad Ibnul Ḥanafiyyah asked his father 'Alī ibn Abī Ṭālib: "Who is the best person after the Messenger of Allāh ﷺ?" He said: "Abū bakr". [Bukhāri] (8) An-Nawawī states: وأفضل الصحابة بالإجماع هو أبو بكر "And Abū Bakr is the greatest Ṣaḥābī by consensus." [Sharḥ Muslim (2381)] 4. Therefore, whoever discredits the superiority of Abū Bakr (over the rest of the Companions), or gives precedence to anyone over him, has not only opposed the 'Aqīdah of Ahlus Sunnah Wal Jamā'ah, but he has also opposed all of these evidences together with the consensus of the Ṣaḥābah.
