HAZRAT KHALID BIN WALEED was an Arab Muslim commander in the service of the Islamic prophet Muhammad and the caliphs Abu Bakr (r. 632–634) and Umar (r. 634–644) who played a leading role in the Ridda wars against rebel tribes in Arabia in 632–633 and the early Muslim conquests of Sasanian Iraq in 633–634 and Byzantine Syria in 634–638.

A Biographical Study of the Greatest Military General in History. Khalid Bin Al-Waleed was one of the greatest generals in history.  Abu Bakr (RA) said 'Women will never give birth to the likes of Khalid Bin Al-Waleed.'   Truly one of the most brilliant biographies written on the Companion of the Prophet (SAWS), Khalid bin Al-Waleed, is the Sword of Allah by Ibn Kathir. Ibn Kathir wrote the original story in his book Al-Bidayah wan-Nihayah. Khalid bin al Waleed (RA) said: "If I were to marry a beautiful woman whom I love, or if I were given the good news of having a newborn son, it is less beloved and dear to my heart then to be, in a cold icy night, in an army waiting to meet the enemy the next morning.  These were the words of Khalid before his death.

Khalid died in 642, and his tombstone shows a list of over 50 major battles he won. Not only was he unbeaten in combat, Khalid never even lost a skirmish or a duel!

Khalid is one of the few generals in history to have never lost a pitched battle. Indeed, he emerged the victor in every single one of the 50 or so large scale battles he fought against the Apostate tribes, Christian Arabs, Sasanian Empire, and Byzantine Empire.

Khalid is considered "one of the tactical geniuses of the early Islamic period" by Donner. In Kennedy's assessment, Khalid was "a brilliant, ruthless military commander, but one with whom the more pious Muslims could never feel entirely comfortable". He notes that the medieval "Arabic narratives give pride of place to Khalid as the commander who provided the most effective leadership, even after Umar had dismissed him from supreme command" and "his reputation as a great general has lasted through the generations and streets are named after him all over the Arab world". While recognizing his military achievements, the traditional sources present a mixed assessment of Khalid due to his early confrontation with Muhammad at Uhud, his reputation for brutal or disproportionate actions against Arab tribesmen during the Ridda wars, and his military fame which disturbed the pious early converts to Islam. According to the historian Richard Blackburn, despite attempts by the Islamic traditional sources to discredit Khalid, his reputation has developed as "Islam's most formidable warrior" during the eras of Muhammad, Abu Bakr, and the conquest of Syria. The historians Carole Hillenbrand calls Khalid "the most famous of all Arab Muslim generals" and R. Stephen Humphreys describes him as "perhaps the most famous and brilliant Arab general of the Riddah [sic] wars and the early [Muslim] conquests". Khalid is considered a war hero by Sunni Muslims, while many Shia Muslims view him as a war criminal for his execution of Malik ibn Nuwayra and the immediate marriage of his widow, in contravention of the traditional Islamic bereavement period.

In the end, I will say my hero is Khalid bin Waleed. ❤️
