Another point to consider is that those guaranteed Paradise should include those who sacrificed their lives and properties in the path of Allah, so why were not the hundreds of martyrs and companions included in this hadith? For example, the “Leader of the Martyrs ( Sayyid al-Shuhada ),” Hamzah, the uncle of the Holy Prophet is not included in this hadith, nor are any of the Ansar whom the Holy Prophet constantly praised.
Above that, to guarantee Paradise to Talha, Zubayr, Abd al-Rahman Ibn Auf, and ‘Uthman Ibn al-Affan would bring about a problem for several reasons. First, Talha, Zubayr, and Abd al-Rahman Ibn Auf used to call ‘Uthman a “ fasiq ” (indecent), and they eventually revolted against him during his caliphate. In addition, Talha and Zubayr pressed for a civil war by supporting and joining Lady Aishah in the Battle of the Camel, in which both of them were killed in the battle.
Secondly, ‘Uthman and Abd al-Rahman Ibn Auf (whom ‘Umar nicknamed “the Pharaoh of this nation”[^9]), after a falling out, did not speak to one another until death.
Furthermore, after ‘Uthman’s assassination, the Muslims were so angry with ‘Uthman that they did not allow for his body to be buried in al-Baqi cemetery; hence, his remains were buried in the Jewish cemetery of Kokab.[^10] He remained buried there until Mu’awiyah came to power and included him in the common cemetery of al-Baqi, in Madinah. To add, Sa’d Ibn Abi al-Waqqas refused to pay allegiance to Imam ‘Ali even when the rest of the ummah accepted him as their fourth caliph.
Nevertheless, many Muslim leaders still cite this fabricated hadith, and many Muslims embrace it unquestioningly. ‘Umar Ibn al-Khattab Many of the fabricated hadith were introduced to provide religious legitimacy for the government of the caliphs. In fact, that could be seen as the primary motive for inventing hadith.
For this reason, many posthumous narrations are recorded in praise of ‘Umar Ibn al-Khattab; some of which are attributed to the Prophet having said them, others to Imam ‘Ali, and some are attributed to various companions. However, almost all of these hadith are flawed as either they contradict the Qur’an, the sunnah or other established facts, or one or more of their narrators are known to be unreliable, according to the standards of recognizing the hadith in the Sunni tradition.
