The mercy of Allah, Exalted is He, is infinite, He accepts the repentance of people regardless of their sins, forgives those who disobeyed Him regardless of their disobedience, and rewards those who believe in Him and do good abundantly. In this hadeeth, Aboo Hurayrah (may Allah be pleased with him) reports that he emigrated from Yemen to the Prophet ﷺ after he conquered Khaybar, a town which waspopulated by Jews and located about 135 km from al-Madeenah on the route to the Levant. The conquest of Khaybar happened in the 7th year of Hijrah. Aboo Hurayrah (may Allah be pleased with him) met the Prophet ﷺ before his return to al-Madeenah and he asked him for a share from the spoils the Muslims had seized from Khaybar. However, one of the sons of Sa’eed ibn al-‘Aas – Abaan ibn Sa’eed (may Allah be pleased with him) – asked the Prophet ﷺ not to give him a share. In response, Aboo Hurayrah said that Abaan was the killer of Ibn Qawqal. He was referring to the incident that happened before Abaan embraced Islam,whenhe killed a Muslim man by the name of al-Nu’maan ibn Tha’labah, a.k.a. Ibn Qawqal (may Allah be pleased with him). Upon hearing this, Abaan insulted Aboo Hurayrah (may Allah be pleased with them) and said: “I wonder at a Wabr,” i.e., he likened Aboo Hurayrah to a small animal that looks like a cat. It is said that it is a word used to describe a person of no significance,since Aboo Hurayrah had no tribe to defend him. He further added that Aboo Hurayrahwas just a man who came to al-Madeenahalong with those who came from the land of Daws, which is the homeland of Aboo Hurayrah (may Allah be pleased with him). Lastly, he said: “He blames me for killing a Muslim man whomAllah has given honourthrough me, and Allah did not disgrace me at his hands,” i.e., he blames for killing a Muslim man that Allah, Exalted is He, has blessed with martyrdom at my hand, while Allah did not disgrace me (as I wasn’t killed) at his hand at that time when I was a disbeliever, so I did not enter Hellfire. Abaan embraced Islam before Khaybar and after Hudaybiyyah. One of the sub-narrators of the hadeeth remarked that he did not know if the Prophet ﷺ gave Aboo Hurayrah(may Allah be pleased with him) a share or not. This hadeeth shows that Islam wipes out all the sins one committed before Islam..
