Khadija bint Khuwaylid was born in Makkah 15 years before A'am Al-Fil (Year of the Elephant). Before her marriage to the Prophet (PBUH), she was married twice. She was widowed and she was left with great wealth making her one of the richest ladies in Makkah. Khadija was also of a very noble lineage and even in the time of jahiliyyah (before Islam), she was known as Al-Tahirah (the pure) and Khadija Al-Kubra (the great Khadija). She needed someone to be in charge of her caravan in their trip to Syria and chose the Prophet Mohammed (PBUH). Who could be better? Because of his honesty and trustworthiness, people called him Al-Saddiq Al-Amin (the Honest and Trustworthy).
Khadija after hearing these accounts of Mohammed (PBUH), proposed to him. He accepted and they were married when the Prophet (PBUH) was at the age of 25 and she was 40.
"She believed in me when no one else did; she accepted Islam when people rejected me; and she helped and comforted me when there was no one else to lend me a helping hand."
Read, in the name of your Lord who created, created man from a clot, Read, and your Lord is the Most Gracious, Who taught with the pen, taught man what he did not know. (Quran 96:1-5)
The Prophet (PBUH) questioned, "Will they drive me out?"
"Yes," he replied, "no one has come with what you have been given without being treated with enemity; and if I were to live until the day when you are turned out, then I would support you with all my might."
Waraqah also felt the seal of prophethood on the Prophet's back and recognized it to be one of the signs of the Prophet (PBUH) that had been mentioned in the Torah.
Khadija was the first person to be given glad tidings of paradise while still in this life.
He often sent food to Khadija's old friends and relatives and spoke highly of Khadija.
