John the Baptist in Islam
Yaḥyā ibn Zakariyyā, identified Biblically as John the Baptist, is considered in Islam a prophet of God who was sent to guide the Children of Israel. He was the maternal cousin of Isa and believed by Muslims to have been a witness to the word of God, heralding the coming of Isa al-Masih.
Yahya is mentioned five times in the Qur'an. Yahya is also honoured highly in Sufism as well as Islamic mysticism, primarily because of the Qur'an's description of Yāhya’s chastity and kindness. Sufis have frequently applied commentaries on the passages on Yāhya in the Qur'an, primarily concerning the God-given gift of wisdom which he acquired in youth as well as his parallels with Isa. Although several phrases used to describe Yahya and Isa are virtually identical in the Qur'an, the manner in which they are expressed is different.
Birth
The Qur'an frequently mentions Zakariya's continuous praying for the birth of a son. Zakariya's wife was barren and therefore the birth of a child seemed impossible. As a gift from God, Zakariya was given a son by the name of Yāhya, a name specially chosen for this child alone. In accordance with Zakariya's prayer, God made Yahya and Isa, who according to tafsir was born six months later, to renew the message of God, which had been corrupted and distorted by the Israelites.Yahya and Isa were maternal cousins, although it is contested whether Isha', Yahya's mother, was Maryam's aunt or sister.
The Qur'an says that Yāhya was the first to receive this name but since the name Yoḥanan occurs many times before Yāhya, this verse refers either to Islamic scholar consensus that "Yaḥyā" is not the same name as "Yoḥanan" or to the Biblical account of the miraculous naming of John, which accounted that he was almost named "Zacharias" after his father, as no one in the lineage of his father Zacharias had been named "John" before him. The Qur'an says:
Prophethood
Yahya was exhorted to hold fast to the scripture and was given wisdom by God while still a child. He was pure and devout, and walked well in the presence of God. He was dutiful towards his parents and he was not arrogant or rebellious. Yahya's reading and understanding of the scriptures, when only a child, surpassed even that of the greatest scholars of the time. Islamic tafsir narrates that Isa sent Yahya out with twelve disciples, who preached the message before Jesus called his own disciples. The Qur'an says:Yahya was a classical prophet, who was exalted high by God for his bold denouncing of all things sinful. Furthermore, the Qur'an speaks of Yahya’s gentle piety and love, as well as his humble attitude towards life.
According to Islamic tradition, Yahya used to go to the Al Haram Ash-Sharif (Temple Mount) to deliver his sermons.
